26 EKOTYLIM. 



3. Nomotus capetillensis. 



Nigro-seneus, nitidus, subcylindricus ; capite prothoraceque crebre distinctius pnnctatis ; elytris punctato- 

 striatis, stria suturali fortius impressa ; pedibus nigris, basi et tibiis interdum picescentibus. Long. 

 8-9 millim. 



Hab. British Honduras, R. Hondo {Blancaneaux) ; Guatemala, Cerro Zunil, Cape- 

 tillo, Chacoj [Champion). 



A species differing from N. wnescens by its smaller size, rather more parallel form, 

 and the more distinct and rather sparser puncturing of the thorax. The series of 

 specimens from Capetillo all agree very closely in these characters, and with them I 

 unite a single example from the E. Hondo ; this latter is rather narrower and quite 

 black, and may prove to belong to a distinct species. 



ORTHOLANGURIA. 



Ortholanguria, Crotch, Cistula Ent. i. p. 395 (1876) \ 



In addition to the characters given l I add the following : — Tarsi clothed with short 

 thick hairs on the soles ; antennse set in deeply margined sockets, there being a space 

 between the eye and socket ; the epistoma ill-defined by a depression ; the ocular 

 canthus bordered above by a straight, smooth, ridge, the striola short and not deep ; 

 scutellum transverse, punctured {0. concolor) or only impressed {0. batesi) ; prosternum 

 broad, margined, truncate, but little excised, and much depressed at its apex ; meso- 

 sternum coarsely punctured ; ventral apical plate of the abdomen rather broadly rounded, 

 faintly emarginate, not distinctly punctate, nor very pubescent {0. batesi). 



The species we record from Mexico is much smaller than, but otherwise very similar in 

 build to, 0. concolor ; the two described by Crotch (0. batesi and 0. concolor) are both 

 from Tropical South America. 



1. Ortholanguria elongata. (Tab. I. fig. 23.) 



Picea, subtus rufo-picea, antennis pedibusque fere nigris ; capite crebrius, protborace parcius et minute, meso- 

 sterno fortiter, punctatis ; elytris nigro subcseruleis, fortiter punctato-striatis. Long. 9 millim. 



Hab. Mexico, Jalapa {Edge), Toxpam, Juquila {Salle). 



Head with the eyes not wider than the thorax, pitchy. Antennse with the seventh joint 

 small but triangular; the eighth, ninth, and tenth joints strongly transverse, being more 

 produced on their inner sides than on the outer, the eleventh joint subquadrate but not so 

 wide as the tenth, the whole club consequently short and round. Thorax longer than 

 wide ; pitchy, the disc darker and faintly bluish ; the base margined, and with coarser 

 punctures ; and with very slight traces of a basal striga. Elytra with the tips round, a 

 little acuminate, and obsoletely denticulate. Femora rather stout and a little sinuate. 

 Underside of the body, the coxae, and trochanters pitchy-red. Five specimens. 



Obs. The apical ventral segment in this species is not at all emarginate ; but this 

 character in 0. batesi is very slight, and perhaps indicates a sexual difference only.
