Body bright luteous, heavily marked with blackish fuscous ; on the pronotum the markings are very irregular, but consist in the main of the following: on either side of the front margin a large transverse fuscous spot, which reaches neither the mediodorsal line nor the lateral margin and is interrupted below by a roundish spot and above by the incursion from the anterior margin of a short narrowing dash ; in the middle of the dorsum a quadrate spot divided by a mediodorsal luteous line into a pair of longitudinal bars, each connected anteriorly with the before mentioned anterior spot, and leaving a luteous sub marginal anterior mediodorsal spot; an infero-posterior black spot not touching the margin; and a laterodorsal subtriangular spot on the posterior margin ; on the succeeding thoracic segments, and on the abdominal there is a series of large irregularly triangular laterodorsal spots on the posterior margins, and another lateral series of roundish or transverse spots generally not reaching any margin; the legs are luteous, the fore and middle femora more or less infuscated in longi tudinal streaks, the hind femora dull luteous with scalariform fuscous markings. Antennae moderately slender, about twice the length of the body, the legs moderately long. Fore femora scarcely stouter than the middle femora, less than a fifth longer than the pronotum, much less than half as long as the hind femora, the inner carina with a tolerably long subapical spine sometimes accompanied by another minute one. Middle femora with a long subapical spine on the front carina, accompanied at least in the male by a couple of others smaller, and on the hind carina one or two short spines at least in the male, accompanied by a long genicular spine. Hind femora moderately slender, fully three times as long as broad, two and a third times longer than the fore femora, the surface with a few scattered raised points on the distal half and especially along the upper edge of the inner surface, the outer carina with 6-8 very unequal and inequidistant spines, the longest about as long as the tibial spurs (male) or wholly unarmed or with a few raised points apically (female), the inner carina very distantly and subequidistantly serrulate, finer in the female than in the male, the intervening sulcus moderate. Hind tibice straight in both sexes, slightly longer than the femora, armed beneath with a single subapical spine, besides the apical pair ; spurs subalt?rnate, the basalnear the end of the proximal fourth of the tibia, about half as long again as the tibial depth, set at a varying angle with the tibia, the outer series at least in the male being directed outward, the inner series both inward and posteriorly, divaricating about 120 degrees, the tips incurved; inner middle calcaria considerably longer than the outer, more than twice as long as the others or as the spurs, and nearly as long as the first joint of the tarsi. Hind tarsi fully two. fifths as long as the tibise, the first joint fully as long as the remaining joints together, the second three times as long as the third and with it as long as the fourth. Cerci very slender and tapering in their distal half, stouter and subequal in their proximal half, scarcely so long as the femoral breadth. Ovipositor about half as long as the hind femora, straight, slender and equal beyond the basal third, the tip produced, acuminate and upturned, the teeth long, aculeate, arcuate.
Length of body, male 15 mm., female 12 mm.; pronotum, male and female 4.5 mm.; fore femora, male 5.25 mm., female 5.1 mm.; hind femora, male 12.2 mm., female 11.5 mm.; hind tibia, male 13.1 mm., female 12 mm.; ovipositor, 5.5 mm. |
