EROTYLID/E 147 



recent general catalogue edited by Dr. Schenkling. As pointed 

 out by Gorham, they have a very peculiar geographic distribution, 

 being components of most faunas though altogether unknown in 

 Europe, Madagascar and New Zealand. Their peculiarly slender 

 and elongate form of body is scarcely even suggested by any other 

 Erotylid type. 



Langurites Mots. 



It seems quite certain that the confusing differences observable 

 among individuals at present classed together under the specific 

 name Langurites lineatus Cast., are not all due to variability; closer 

 and more careful study with ample material, would doubtless show 

 that a number of distinct species are now commingled. This is, 

 at any rate, true of the two forms that I describe below; for they 

 seem to be unequivocally distinct species fiom every point of view, 

 though apparently variable in coloration : 



*Langurites apiciventris n. sp. Elongate-fusiform, convex, polished and 

 glabrous, testaceous throughout, excepting a small spot on the occiput, 

 a median vitta on the pronotum and a marginal stripe on the latter in- 

 cluding the thick side margins, the scutellum and entire elytra, excepting 

 a medio-basal region on each, gradually fading out in basal fifth or sixth, 

 and the last two ventral segments, all of which are black; legs and coxae 

 deep black throughout, excepting the feebly rufescent extreme base of 

 all the femora, and the antei.nae are also deep black throughout; head 

 excessively minutely and remotely punctulate, the superciliary ridges 

 broad, limited within by a fine incised line; eyes large, prominent and very 

 finely faceted; antennae slender, not quite extending to the base of the 

 prothorax, the 4-jointed club gradually formed as usual; prothorax of the 

 usual outline, a fourth longer than wide, with the base a little wider than 

 the apex, impunctate, the base lobed medially, the transverse sulcus 

 straight; scutellum very smooth, convex and subcircular; elytra at base 

 rather suddenly wider than the prothorax, gradually attenuate, nearly 

 four times as long as wide, the punctures of the scarcely impressed series 

 very gradually disappearing apically and more rapidly basally; abdomen 

 impunctate, becoming strongly and densely punctate at the apex of the 

 last segment. Length (9) 12.8 mm.; width 2.35 mm. Mexico (Guer- 

 rero), Baron. 



There is no intimation made by Gorham that the entire abdomen 

 in lineatus is not red, and it is so described by Horn (Tr. Am. Ent. 

 Soc., 1885, p. 139) in the case of an Arizona specimen supposed by 

 that author to be lineatus; here, the last two ventrals are wholly and 

 abruptly black and the locality the western slope of Mexico is 

 different from any recorded by Gorham in the " Biologia."
