Bod}^ oblong-ovate, about two and a half times longer than wide, 

 7 nuu. : 18 mm. 



Head about twice as wide as long, rounded anteriorl}- and produced 

 in the middle in a small, narrow process, separating the basal articles 

 of the antenna? and meeting the small frontal lamina on the other side. 

 The eyes are large, oblong, and conspicuous, occupying almost the 

 entire surface of the head and contiguous in the median line. The 

 first two articles of the first pair of antenna^ are small and equal in 

 length; the third article is long and narrow, nearly three times as long- 

 as the second article. The flagellum is composed of sixteen articles. 



«The above description is adapted from the following one of Schicedte and 

 Meinert' s: 



Ovata, supra pra-ter punctnram ordinariam punctis minutis, perraris sparsa. 



Frons bisinuata, acumine procumbente dimidiam partem artieuli i»rimi anten- 

 narum primi paris discernente. 



Lamina frontalis rhomboidalis. Oculi magiii, ol)longi, post acuminati, seriebus 

 ternis ocellorura contigui. 



Antennse primi paris angulum posticnm annuli primi trunci vix attingentes, scape 

 articulum quartum, flagello articnlum deoimum antennarum secundi paris explentes; 

 flagellum 7-8— articulatum, articulo prinio perlongo, tenui, articulos tres sequentes 

 conjunctos longitudine pequante. 



Antennae secundi paris dimidiam partem epimeri quinti explentes; flagellum 21 — 

 articulatum. Segmentum dorsale annuli prinu trunci ante late emarginatum; seg- 

 nientum dorsale annuli septimi maximam partem obtectnm. 



Epimera latiuscula; anguli postici epimerorum posteriorum acuti, paulum pro- 

 ducti; epimerum ultimum annnlum primum caudalem explens. Pedes prensorii 

 graciles, subglabri; femora angustiuscula; ungulse primae pusilli^e, posteriores ali-

 multo longior et duplo latior, post in obliquum late rotundatus; ramus uterque post 

 in dentes jjlures obtusiusculos desinens.
