Subfamily Derbinae. 



204. Otiocerus Degeeri Kirby. 

 Sevenoaks; one strongly colored example. 



205. Cenchrea fulva n. sp. 



Very closely allied to Heidemanni Ball but with a narrower and more 

 deeply channeled front. Elevated margins of the vertex as high as the 

 width of its carinate base. Front distinguished from the vertex by a slight 

 angle but the dividing line not at all carinate; narrow, but little broader at 

 apex; the edges greatly elevated; middle line feebly carinate. Eyes vertical, 

 sinuated behind and strongly narrowed below. Second joint of the antennae 

 large, ovate, but not nearly attaining the margin of the post-ocular cavity 

 in which it stands; setae short, black. Pronotum shorter than the dorsal 

 aspect of the vertex, angularly emarginate behind; on either side produced 

 in a semicircular auriculate cavity for the reception of the antennae; the 

 elevation of the posterior wall of this cavity is about equal to the length of 

 the pronotum. Mesonotum transverse, convex, polished and very obscurely 

 tricarinate on the disk; the obtuse triangular apex depressed. Elytra long 

 and narrow; the outer claval nervure distinctly granulate. Genital plates 

 of the male with their inner margins strongly toothed at the middle leaving 

 a rounded opening at base and an oblong one apically. Length to tip of 

 the abdomen $ l A mm.; to apex of the closed elytra 6%. mm. 



Color obscure rufo-fulvous, deeper on the abdomen and paler or sub- 

 testaceous on the elytra; eyes, slender edge of the facial carinae and stiles of 

 the male black. Wings and plates of the male whitish, the nervures of the 

 former brownish; apical margin of the elytra slightly enfumed and very 

 minutely serrate. 



Described from one male taken at Estero. This large 

 species may readily be distinguished by its pinkish color. It 

 differs from the closely related Heidemanni Ball by its narrow 

 and deeply sunken vertex and front and the fulvo-testaceous 

 elytra. It has a much more produced vertex than Uhleri. 

 Our dark slate colored Lamenias differ from these species in 

 having a shorter and broader vertex which is separated from 

 the front by a transverse carina which is sometimes obscure, 

 and in having the margins of the front and vertex much less 

 elevated and the elytra shorter. My Lamenia flavida from 

 Jamaica is strictly intermediate between these genera. 



206. Lamenia obscura Ball. 



Taken at Crescent City and Haw Creek. Unfortunately 

 only females were brought home so I cannot be certain of this 

 identification but the specimens agree in almost every particular
