CATALOGUE OF ORTHOPTEROUS INSECTS. 



Glossy black ; the head, pro-, meso- and metathorax with 

 an ill-defined longitudinal chestnut-red vitta on each side ; 

 the legs and antennae pitchy ; the body beneath pitchy- 

 black and rather glossy. The head has two minute im- 

 pressions near the anterior margin behind the antennae, 

 and two others in the front of the crown. The head, pro- 

 and metathorax, as well as the abdomen, are destitute of 

 spines ; but the nicsothorax is spinulose towards the an- 

 terior angles. The body is gradually widened from the 

 head to the middle legs ; the metathorax is rather oblong, 

 the sides slightly dilated. The abdomen of the male is 

 gradually narrowed from the base to the seventh segment, 

 which, with the eighth and ninth, form a short oval club, 

 the ninth being notched at the tip, with two curved setose 

 st3'les beneath ; the terminal ventral segment does not ex- 

 tend to the middle of the ninth dorsal one ; the eighth 

 ventral segment being short and constricted at the sides. 

 The abdomen of the female is gradually narrowed from the 

 base to the ninth segment, which is rounded behind, ex- 

 posing the extremity of the two styles (fig. 5 a**). The 

 operculum does not extend beyond the middle of the ninth 

 dorsal segment, exposing a flattened bipartite membranous 

 piece (.5 a u). The legs are rather short and robust, en- 

 tirely simple ; the fore femora scarcely curved at the base.

The male is glabrous and coloured in the same way as 

 the female, but with the markings more suffused (possibly 

 the effect of grease). The head is short and broad, punc- 

 tured on the disc with two minute impressions between the 



eyes ; the upper lip is prominent and rounded ; the antennae 

 are short and 20-jointcd. The prothorax is wider than the 

 head, with the anterior angles rounded, exposing the spi- 

 racles ; the disc is rather uneven and slightly punctured. 

 The mesothorax is considerably dilated, its dorsal portion 

 elevated, and furnished at its hind part with a pair of flat, 

 semiovate, elytriform, dark greenish-brown wing-cases, 

 strongly reticulated, but immoveable, and only extending 

 over the basal part of the metathorax, which latter is 

 spotted like the segments of the abdomen, and bears a pair 

 of minute rudimental wings, of a dirty straw colour, and 

 soldered to the surface at its base. The abdomen is elon- 

 gate, gradually narrowed from the base to the seventh seg- 

 ment in the male, the three terminal segments formmg 

 an oval mass ; the three terminal ventral segments short 

 and gaping widely, exposing the complicated male organs 

 of generation. The abdomen of the female is broader and 

 swollen, the lateral margins being more membranous than 

 the disc ; it is gradually narrowed from the base to the 

 extremity, which is rounded and entire. The operculum 

 is short and flat, not extending beyond the middle of the 

 eighth dorsal segment. The legs are dirty olive-brown, 

 mottled with buff; they are short and very strong, and 

 entirely destitute of spines ; the fore femora are not bent 

 at the base. The body beneath is pale luteous-buff, very 

 slightly spotted with dark brown.

 three terminal segments of the abdomen seen from beneath. 

 1 b. The same seen sideways. **. The two anal styles, 

 t. A small, central, curved, horny point. J. Two horny, 

 flattened, curved appendages ; the right-hand one (as seen 

 from below) much longer than the other, o o. Two conical 

 elongated leathery lobes. 



Obs. There is only one fully-developed male in the 

 National Collection, and the anal appendages may possibly 

 have become distorted in their position whilst drying.

7. (47.) Anisomorpha crassa.

 in mare ; antennis fusco-testaceis, basi obscurioribus ; meso- 

 thorace prothoracis longitudine ; elytris squamiformibus, 

 valde reticulatis ; pedibus crassis, carinatis, puuctatis.
