3. (39.) Pachymorpha Hystriculea. Plate I. fig. 4. 

 Fusca, rugosa, opaca, spinisque numerosis armata ; 

 lateribus mesonoti ferrugineis ; segmentis apicalibus ab- 

 dominis lutescentibus ; antennarum articulis nonnullis inter- 

 mediis apice obscuris ; capite inter oculos tuberculis duobus 

 instructo, abdominisquc segmento 4to lateribus dilatatis fo-

 Hab. Nova Zealandia. B.M. 



The head is widened from the hind part to the eyes, be- 

 tween which are two obtuse tubercles irregular at the top, 

 and behind each of these is a row of small raised granules. 

 The antennae are very short, 16-jointed, with the seventh, 

 tenth, thirteenth and sixteenth joints dark at the tips. The 

 prothorax is as large as the head, with two small spines on 

 its hinder part. The mesotlforax is armed with two spines 

 near its anterior extremity, two near the middle, and two 

 near the hind margin, scarcely placed in regular pairs, and 

 the hinder extremity is armed with several smaller spines. 

 The metathorax bears a pair of spines near its fore end, and 

 its extremity is dilated and armed with several divergent 

 spines ; the six basal segments of the abdomen are armed 

 with a spine on each side near the base, the fourth seg- 

 ment being furnished with a dorsal aud two lateral foliaceous 

 rugose appendages ; the terminal segments of the abdomen 

 are narrower than the others. The operculum extends be- 

 neath the seventh, eighth, and base of the ninth segments ; 

 it is emarginate at its tip, and the ninth segment is fur- 

 nished beneath near its tip with two deflexed styles. The 

 body beneath is rugosely granulated, with a few small spines 

 arranged symmetrically on the abdominal segments. The 

 legs are of moderate length, the fore femora curved at 

 the base, and slightly serrated on the upper edge ; the four 

 posterior femora are armed with three or four small spines 

 both on the anterior and posterior margins ; the tibiee are 

 furnished with a few small serratures.

4. (40.) Pachymorpha? Omphale, Westw. 

 Plate II. fig. 5. 



Lutea (viridis insecto vivente ?), opaca, supra carina lon- 

 gitudinali mediaua alterisque tribus minoribus utrinque e 

 capite ad anum extensis, corpore e fronte ad segmentum 

 6um abdominis sensim dilatato, segmentis reliquis atte- 



nuatis ; cercis duobus analibus porrectis ; operculo fere ad 

 apicem abdominis extenso (fcem.).

Hab. In Africa australi. B.M. 



Entirely opake and of a dirty luteous colour (probably 

 green whilst alive), and distinguished by a strong raised 

 line extending down the middle of the back from the head 

 to the extremity of the body, having moreover three slender 

 carina; on each side of the central one, the middle one of 

 the three on each side being less distinct than the other 

 two ; the outer margin of the body is acute and margined ; 

 beneath, the body is furnished with five similar longitudinal 

 carinae, besides another on each side close within the lateral 

 margin. The head is rather small. The antennae very 

 short, about 20-jointed, the basal joint being large and di- 

 lated. The body is gradually dilated from the head to the 

 sixth segment of the abdomen, behind which it is attenuated, 

 being terminated by two small oval appendages ; the oper- 

 culum itself nearly extending to the extremity of the ninth 

 segment of the abdomen. The legs are short and simple, 

 the anterior femora curved at the base ; the tibiee are 

 straight and slender.

Genus 3. ANIS0M0RPHA. 

 Anisomorpha, G. R. Gray, Burm., Be Huan. 



Body rather short, cylindrical in the male, robust and 

 subdepressed in the female, glabrous. Antennae mode- 

 rately long, multiarticulate, second and third joints of equal 

 length. Legs unequal, those of the males long, those of 

 the females short and robust ; basal joint of the tarsi short. 

 Mesothorax occasionally furnished with rudimental tegmina.
