86 Mr. Gr, C. Champion's Revision of the Mexican 



is before me. It is larger than L. serricornis ; the head, 

 antennae (the basal joints excepted), legs, and elytra (a 

 short obhque streak before the middle of the disc excepted), 

 are black ; the prothorax is rufous, with a black patch on 

 the disc in front ; and the antennae are feebly serrate. The 

 male of L. mancus is unknown. The antennae are serrate 

 in both sexes of L. serricornis, these organs being long and 

 acutely dentate in the male. Another species has been 

 described by Pic, L. albofasciatus, from Brazil. 



Dromanthus.

 pp. 121, 322. 

 There is but httle to add to Gorham's descriptions of 

 the six species he included under Dromanthus, except to 

 call attention to the pecuUar structure of the posterior 

 tarsi of the males of certain forms, only a single specimen 

 (of D. opacus) having come to hand since 1886. The tarsi, 

 it may be observed, are described as 4- jointed, the minute 

 additional penultimate joint (formed exactly as in Lemphus) 

 having been overlooked. D. jucundus, Gorh., would 

 perhaps be better placed under Lemphus, in which the 

 elytra are rather short, and the last three or four abdominal 

 segments are exposed in both sexes; but as the male is 

 unknown, it can remain under Dromanthus for the present. 

 Various S.- American forms have recently been added to 

 the genus by Pic.

(^. Antennae with joints 6-10 broadly widened, becoming nar- 

 rower outwards, 11 considerably narrower than 10; posterior tarsi 

 with joint 1 curved and produced at the inner apical angle into a 

 long slender process which reaches as far as the apex of 2, 2 also 

 curved and elongated.

The description was made from a single immature $ 

 example from Playa Vicente, Vera Cruz ; the male is from 

 Cordova.
