166 THE ENTOMOLOGIST. 



Gelastaspis, gen. nov. 



Closely allied to Ceratocoris, White, and more especially Libyaspis, 

 Kirkaldy, but differs from them by the form of the head (at least in 

 the males). 



Roundly convex. The upper surface, the head beneath, and the 

 laminate parts of the sterna closely but irregularly punctured. Head 

 horizontal, tylus small but distinct. Eyes small. Ocelli close to base 

 of head. Buccul® very short, elevated, anteriorly not touching clypeus. 

 Head (with eyes) narrower than the apical margin of the pronotum ; 

 antennsB inserted a little nearer to the base of the rostrum than to the 

 eyes. Head strongly callosely tuberculate between insertion of an- 

 tennae and intero-basal part of head, and also callosely elevated between 

 the former and the eyes. Apical margin of pronotum widely and 

 minutely emarginate, briefly truncate in the middle. Pronotum strongly 

 elevated posteriorly, sinuately impressed in the middle on the anterior 

 margin, lateral margins rounded. Prosternum strongly and pro- 

 foundly depressed between the true sterna and the expanded laminate 

 parts. Mesosternum laminate laterally. Stink-orifices simple, elon- 

 gate. Coxse almost contiguous. Spiracles at lateral margins of 

 abdominal segments, not on connexivum. 



^ . Tylus very short, juga meeting in front of the eyes, and pro- 

 duced somewhat overlappingly, about 3f times (or more) as long as 

 tylus (to base of head) ; juga not forming a single curve together, the 

 anterior margin of head being thus angularly emarginate in the 

 middle. Antennte very short, second segment one-half longer than 

 the first, which is subequal to the third, fourth one-seventh longer 

 than third. Distance between an ocellus and the nearest eye about 

 three times as great as between the ocelli. Fifth abdominal segment 

 (Verhoeff's nomenclature) beneath apically acutely emarginate, nearly 

 touching apex of fourth in the middle ; sixth beneath apically rotund- 

 ately emarginate. 



? . Tylus more rounded, and shorter than in the male. From 

 base of head to apex of tylus, scarcely shorter than the length of the 

 juga in front of tylus. Eyes sessile. Second segment of antennas 

 about equal in length to the first. Distance between an ocellus and 

 the nearest eye about seven-twelfths greater than between the ocelli. 

 Apical margin of fifth segment of abdomen beneath obtuse-angled 

 emarginate, sixth rotundately emarginate. 



8. G. BRowNi, sp. nov. 



Above flavescent or flavo-testaceous, irregularly speckled, blotched, 

 and marmorate with blackish brown. Beneath black ; the laminate 

 parts flavescent, variegated as above. Antennte, rostrum, legs, &c., 

 pale rufo-testaceous. Abdomen beneath laterally more or less pallid 

 in wedges. First segment of -rostrum reaching to the middle of the 

 prosternum, second to middle of mesosternum, third to middle of meta- 

 sternum, fourth reaching beyond posterior coxge. Long. ^ 13-13J
