Hab. In India? occidentalis insula St. Christopheri 

 (B. Shepherd). In Mus. Hopeiano Oxoniae. 



The general colour of the specimens of this insect in the 

 Hopeian Museum is greenish yellow j when alive, it was 

 probably uniform green, the specimens having been pre- 

 served in spirits. The surface of the body is smooth, but 

 not glossy. The head is deflexed in front, the crown fur- 

 nished with two tubercles, the right-hand one being the 

 larger ; the hind part of the head has several small spines. 

 The antennae are of moderate length, the joints beneath arc 

 black, beyond the middle also every fourth or fifth joint is 

 dark at the tip. The prothorax has two small spines at 

 its hind margin ; the mesothorax is gradually widened, 

 with a few minute tubercles or spines on its disc, two near 

 the fore margin being more distinct ; the sides of the meso- 

 thorax and metathorax are white, the former also armed 

 with a row of small spines. The tegmina are small and 

 somewhat triangularly ovate, green, with the costal margin 

 beneath black ; the wings are very small and hyaline ; 

 the costal area broad, coriaceous, green, with a black spot 

 beneath. The abdomen is long, the anterior segments 

 rather broad, the remainder gradually narrowed to the end, 

 the three terminal ones being more suddenly narrowed. 

 The operculum is boat-shaped, as long as or longer than 

 the two or three terminal segments of the abdomen. The 

 legs are short and robust ; the anterior femora with two 

 or three and the four posterior femora armed beneath with 

 six or eight spines ; the tibiae dilated near the base, the 

 tips with several small spines ; the basal joint of the tarsi 

 short.

Genus 19. HAPLOPUS. 



Aplopus, G. R. Gray (Syn. Phasm. p. 34). 

 Haplopus, Sect. A., Burmeister (p. 57C). 

 Haplopus, Sect. C, Be Haan (p. 127). 



Males with the body elongate and slender, the metatho- 

 racic portion more robust. 



Females broader, subdepressed, with the abdomen 

 greatly elongated, and the oviduct extending considerably 

 beyond the extremity of the abdomen. 



Head in both sexes with two unequal-sized tubercles, 

 that on the right side generally the larger. Ocelli want- 

 ing. Antennae of moderate length. Mesothorax con- 

 siderably elongated, often spinose. Tegmina small, oval, 

 shorter in the females. Wings of the male large ; those of 

 the female very small, not longer than the tegmina, not 

 reaching to the extremity of the metathorax, with but few 

 longitudinal veins. Legs comparatively short, thick in the 

 female, and often spined. Anal styles very small in the 

 female, more elongated and deflexed in the males. 



The species of this group, as here restricted, are natives 

 of the West Indian Islands, the habitat of Amboyna given 

 by Stoll to H. micropterus being clearly erroneous. As a 

 group, they are very closely allied to Biapherodes gigas 

 of Drury ; indeed Gray unites several of them generically 

 with that insect. I cannot, however, separate them from 

 H. micropterus. It would therefore perhaps be more 

 natural entirely to sink the genus Biapherodes, uniting 

 its species with the others.

The elegant coloration of the wing-covers and wings at 

 once distinguishes the present species. It is very long, slen- 

 der and cylindrical ; the general colour luteous brown, but 

 the head, prothorax, and extremity of the abdomen, as well 

 as the antennae and legs, are tinged with green. The head 

 is convex, with two slightly raised tubercles on the crown
