acute, with a small tooth near the tip, pulvilli moderate. Abdomen 

 subsessile, elongate, fusiform, rather convex above with the apex pro- 

 longed and acutely pointed in 9 , subdepressed and obtusely pointed 

 in $ ; basal segment longer than wide, broader at tip ; the second, 

 third and fourth segments slightly broader than long, each with a deep 

 oblique groove on each side above, as in Gbjpta, those on the fourth 

 segment obsolete ; ovipositor not exserted. 



This genus is closely allied to Banchits and Exctastes, but differs 

 from both genera by the broader wings, the shorter and stouter legs, 

 and the remarkable shape of the abdomen of the $ , which is elongate 

 and gradually acuminate towards the tip, which is acutely pointed ; 

 the obliquely grooved dorsum of the second and third segments seem 

 to be a well marked character of this genus, and are similar to those 

 of Glypta. 



Ceratosoma apicalis, n. sp. 



Ferruginous; most of head, sides of mesothorax. spot on pleura, scutelluras. 

 apex of metathorax, posterior tibios and tarsi except tips, and bands on abdo- 

 men, bright yellow; wings deep yellowish-fuscous, apex hyaline. 



Female. — Head yellow, the depressed space behind the antennae 

 black ; middle of the face, clypeus, palpi, and two spots on the occiput, 

 fulvous; tips of mandibles black; antennae about half the length of 

 the body, entirely fulvous. Thorax fulvo-ferruginous ; lateral margins 

 of mesothorax, broad in front and narrow behind, a transverse irregular 

 mark on the disk, sometimes wanting, tegulao, a line beneath the base 

 of anterior wing, a large spot on each side of pleura anteriorly, both 

 scutellums, and the apical half or one-third of the metathorax, some- 

 times reduced to a large spot on each side, all bright yellow. Wings 

 deep yellowish-fuscous, with an obscure brassy gloss ; the anterior pair 

 with the apex, beyond the areolet, hyaline and iridescent; nervures 

 fusco-ferruginous, the costa and stigma fulvous ; areolet large, subtri- 

 augular, or subrhomboidal. Legs bright fulvo-ferru« - inous, the two an- 

 terior pairs tinged Avith yellowish ; posterior tibiae and tarsi vellow, their 

 apical half fusco-ferruginous. Abdomen fulvo-ferruginous, darker to- 

 wards the apex which is elongate and acute; apical margins of the four 

 basal segments with a broad bright yellow band, broadest on the first 

 segment where the band is dilated on each side ; one specimen has a 

 black mark on the extreme basal middle of each segment, larger and 

 more conspicuous on the apical segments which have a dark rufous 

 tinge ; venter more or less compressed, fulvo-ferruginous, stained at 

 base with yellowish. Length 6 — 7 lines; expanse of wings 9^ — 102
