Tethionea. 



Caput subverticale, magis latuin, antice breve, sutnra 

 clypexli arcnati, profunde impressa ; tuberibus an- 

 tenniferis subdepressis. Onili magni, prominentes, 

 profunde emarginati. Antemice corpore longiores ; 

 scapo articulisque tertio et quarto longitudine fere 

 asqualibus, sequentibus longioribus et eequ ilibus. 

 Frothorax subelongatus, paulo depressus, lateribus 

 paulo rotundatus. Elytra oblonga, vix parallela, 

 apicibus uni- bi- vel tri-apiculatis. Per/ps fere ut in 

 Ceresio, sed tarsi niulto longiores, et fere sequales. 

 Prosterniim angustum ; rttesosteruum, sat amplum. 

 Abdomen in maribus breve. Corpus fere glabrum. 



In this genus, which is very distinct from Ceresiiim, 

 I have included C. a-pindatum, which, however^ has some- 

 what shorter antennee than the rest, and a narrower head. 

 In all the species described below, the pubescence con- 

 sists of very short scattered hairs, only visible under a 

 lens. 



§ Elytra with uniapiculate apices. 



Tethionea unicolor (PI. XX. fig. 4) . 



T. fulvo-testacea, pedibus dilutioribus ; prothorace sat 

 lato, lateribus subrotundatis. 



Bah. — Am. 



Rather glossy, entirely fulvo-luteous, the legs paler; 

 head slightly punctured between the eyes ; prothorax a 

 little longer than broad, rather broader than the head, 

 the sides slightly rounded, the disk finely punctured, a 

 slight projection near the base on each side ; scutellum 

 nearly semicircular; elytra finely punctured, the punc- 

 tures gradually fainter beyond the middle, and finally 

 disippearing, a scarcely elevated longitudinal line be- 

 tween the outer margin and suture, the apex of each 

 elytron formed by the oblique truncature of the suture 

 and the incurvature of the outer margin ; body beneath, 

 finely punctured, the abdomen slightly pubescent; man- 

 dibles black ; antennae a quarter as long again as the 

 body, pubescent. 



Length 5| lines.
