Hemipterous Insect from the Atlantic Ocean. '^31 



small rufous maculae are on the sides of the middle line closely ad- 

 joining the prothorax. The eyes are large, rufous, semiglobular, 

 and occupy the space between the base of the head and the pro- 

 cesses of the antennae, emarginating the corselet laterally. The 

 antennae are about f the entire length of the body ; the 1st joint 

 slender and curved outwards, the last thickest, attenuating towards 

 the tip. 



The prothorax is excessively short, collar-like, and gently chan- 

 nelled above into three subequal divisions, which nearly disappear in 

 the dried specimen. The first pair of legs, arising closely to the 

 mesothorax beneath, are moderately long, rather robust; the coxa 

 short, obconic, and curved ; the femur slightly /-shaped, with 4 or 5 

 strong black spines near its base exteriorly ; tibia basally attenuated, 

 arising with a curve from the preceding joint, and with 4 or 5 

 strong black spines inferiorly, apically giving origin to a strong ob- 

 tuse process, which projects backwards and outwards from near the 

 articulation. Tarsus with the two joints subequal, the last dimi- 

 nishing in diameter beyond its middle, after giving attachment to 

 two strong claws and an anomalous horny process on the under side, 

 and also furnished with two long curved spines arising from the back 

 part on each side, and lying adpressed among the hairs. 



The metathorax and mesothorax seem confounded together, pre- 

 senting superiorly a hexagonal figure, a little longer than broad, the 

 anterior side being carried a little forwards, so as to leave the lateral 

 angles behind the centre. The posterior surface is transversely 

 striate from being impressed upon the abdominal rings. The sides 

 in the dried specimen become somewhat hoary from the light thrown 

 back by the minute hairs. Beneath it is somewhat similar in form, 

 but excavated behind, exposing in the sinus the abdominal rings. 

 The sides posteriorly are rugose, with trochantines, from whence 

 proceed directly backwards the coxae of the last 4 legs, that of the 

 posterior pair lying beneath the other on each side. Tlie legs are 

 slender, the middle pair exceeding the first, and the last pair the 

 middle, by about one third. The last also has the apical half of the 

 tibia, and 1st joint of the tarsus, with a row of long hairs beneath. 

 Above the origins of the legs we find rudimentary processes, which, 

 as the insect is apterous, must be looked upon as those of the un- 

 developed wing.
