172 AMERICAN COLEOPTERA. 



The transverse antennal fovea is a very exceptional character, 

 and has been noticed in but two other species, viz., persimile and 

 jibulipes. 



101. A. persimile n. sp. — So exactly like the following species in nearly 

 every particular, that reference need here only be made to the two points of 

 divergence. In fibuUpes the tarsal spine is longer and blunt at tip, and the eyes 

 are broadly oval as usual ; in persimile the tarsal spine is shorter and acute, and 

 the eyes are plainly narrowed inferiorly. (PI. V, fig. 19). 



Several examples in the Zimmerman collection and one female in 

 Dr. Horn's collection, presumably fi'om the same source, are all that 

 I have seen. The specimens bear no locality label, but are, without 

 much doubt, from the South Atlantic Coast region. 



102. A. fibiilipes n. sp. — Moderately robust, entirely black: pubescence 

 rather conspicuous, consisting of perfectly recumbent cinereous hairs, which are 

 more or less squamiform, especially on the head, prothorax and lower surface : on 

 the elytra they form a single, tolerably even line on each interval. Beak ^^^ ) 

 rather strong, shorter than the head and prothorax. feebly dilated close to the 

 base, slightly narrowing to the tip; apex shining, otherwise dull and moderately 

 punctate, the punctures larger and more irregular at the sides; ( 9 ) very slightly 

 longer and more slender. First joint of anteunte short, not as long as the next 

 two, second a little longer than the third, first joint not reaching the eye. Front 

 narrow, about as wide as the tip of the beak, with two confiuent lines of punc- 

 tures; eyes not prominent. Prothorax about one-third wider than long, widest 

 at the base ; sides arcuate between the apical and basal constrictions ; basal mar- 

 gin somewhat expanded ; surface moderately closely, though not densely punc- 

 tate ; basal fovea small. Elytra about one-half longer than the thorax, less than 

 one-half wider than long, subparallel : humeri moderate ; sides feebly arcuate in 

 basal two-thirds; intervals convex ; the hairs arising from the strial punctures 

 are generally visibly shorter and not at all squamiform. Beneath moderately 

 punctate: claws with a small tooth. Length 1.5-1.7 mm.; .0G-.07 inch. (PI. 

 V, fig. 18. ) 



%, . First joint of middle tarsi with a long blunt process on the inner side. 

 9 . Middle tarsi not modified. 



Hah. — Lower California (La Chuparosa). 



There is not much sexual difference in the elytral tips. In addi- 

 tion to the differences stated in the table between this species and 

 aculeatum, it may be added that the present species is considerably 

 more robust, and the vestiture of the elytra consists of only a single 

 line of stouter liairs on each interval, while in aculeatum the hairs 

 are finer and more numerous. The two species are, however, closely 

 related as is evident by the narrow front, feebly toothed claws, 

 peculiar sexual characters, and a general similarity in form, size, 

 sculpture and vestiture. The resemblance to permnile is excessively 

 close, the difference being alluded to under that species.
