genera and species of Langnriidce. 305 



Crotchia, n. g. 



Species convexse, latiores, plus ininusve gibbosiE, ravms augus- 

 tiores ; capita antice producto, oculis fortissime granulatis, antenuis 

 brevioribus, clava abrupte triarticulata ; articulo palporum maxil- 

 larium penultimo brevissimo, secundo distincte breviori; thorace 

 subquadrato, plus minusve transverse, marginato, angulis anticis 

 leviter prominulis, sa3pius callosis ; elytris coiivexis apicibus singu- 

 latim rotundatis ; metasterno sat longo, processu prosternali lato, 

 truncato, utrinque marginato ; pedibus modicis, tarsorum articulo 

 penultimo fortiter bilobo, onychio longissimo ceteris articulis 

 superante ; lineie coxales obsoletae vel nuUae. 



Rather variable in shape, but convex and usually more or less 

 gibbous ; head produced triangularly in front of the eyes, which 

 are prominent and very coarsely granulated ; in front of the eyes 

 there is a pronounced depression reaching across front and marking 

 the clypeal suture ; labium small but usually evident, setose in 

 front ; maxillary palpi with the last joint long, penultimate very 

 short, distmctly shorter than second ; meutum trapezoidal, appa- 

 rently made up of two pieces, distinctly emarginate, with a tooth 

 in the middle of the emargination ; antennae rather short, with the 

 club abruptly three-jointed ; thorax subquadrate, more or less 

 transverse, margined, with the anterior angles well marked, and 

 slightly reflexed or callose at apex ; elytra separately rounded at 

 apex ; tarsi with the penultimate joint strongly bilobed, onychiimr 

 very long, first joints strongly pilose ; metasternum usually long, 

 prosternal process broad, truncate, and margined at sides. 



This genus bears a somewhat strong relation to Para- 

 cladoxena, but is distinguished from it by its different 

 shape (the thorax and elytra not being strangulate at 

 base, as in that genus), the emarginate and denticulate 

 mentum, and the shorter penultimate joint of the 

 maxillary palpi. Motschulsky, in describing Cladoxena, 

 refers to a genus Cladophila, which is not mentioned at 

 all in the Munich catalogue ; at all events this genus 

 appears to be distinct from it, as Von Harold [l. c, p. 63), 

 says that in the genus Cladophila "the second joint of 

 the antennse is longer than the third, whereas in all 

 Langurice the third is the longest of the two"; in the 

 genus now described the third joint is the longest as a 

 rule, but the second and third joints are occasionally 

 subequal in length.
