410 Mr. C. O. Watcrhouse on new Genera 



acute at tlic apox. ^[axilla> short, tlie internal lobe termi- 

 natiiio: in a sliarj) ]ioint ; the external lobe ]n-0(lnee(l Ix'vond 

 the internal lobe, truneate at the aj^ex. The palpi rather 

 large ; the basal joint small, elongate, bent in the middle ; the 

 second joint lar<;er and about twice the leni^th, truncate at 

 the apex ; the third joint rather shorter ; the fourth rather 

 lonu:er than the two precedini>- joints taken together, fusiform 

 ■with the ajiex slightly truncate. Antenna^, with the first 

 joint inflated, second joint a little longer than broad, the third, 

 fourth, and fifth a little shorter, the sixth as long as the second 

 joint; the seventh to tenth forming a long club, tlicsevcnth joint 

 shining. Metasternum rather long ; abdomen short ; the pygi- 

 dium large and triangular, the a])ex reaching in repose to 

 the base of tlie femora. Anterior coxa^. very large. Anterior 

 tibia} rather short, Avitli two strong teeth on the outer edge ; 

 tarsi rather longer than the tibiae ; the inner claw bent at right 

 angles near the base, which is furnished with a small tooth ; 

 the other claw, as well as the claws to all the other tarsi, 

 quite simple, rather slender. Tarsi to the four posterior 

 legs very long and slender, with strong Tjristles at the apex 

 of the joints, the posterior pair nearly three times as long as 

 the tibia. 



I am not satisfied as to the position of this genus. It 

 has somewhat the form of Pac/n/rohis • and I therefore place it 

 temporarily next to the genus TricJiinopiis above described. 



Perissosoma cenescens^ sp. nov. 



P. oblongo-ovata, leviter convexa, aenescens, nitida ; capite sat lato, 

 fronte discrete subtiliter punctulata, antice impressa ; clypeo 

 transverse, antice le\-iter rotundato, crebre distiucte punctate ; 

 thorace capite ^ latiore, longitudine f latiore, leviter convexo, 

 discrete subtiliter punctulato, antice leviter eraarginato, lateribus 

 leviter rotundatis (medio fere angulatis) tenuiter marginatis, basi 

 utrinque levissime siniiata ; scutello triangulari, punctulato ; elytris 

 thorace paulo latioribus, medio paulo ampliatis, ad apicem obtusis, 

 irregulariter striato-punctatis, interstitiis distinete discrete punc- 

 tatis ; sutura elevata, picea ; corpore subtus piceo ; pedibus longis, 

 piceo-seneis, femoribus piceis. Long. 4;^ Hn., Lit. 2\ lin. 



The elytra are rather more distinctly punctured than the 

 thorax, and the striae are only traced near the suture and at 

 the sides.
