58 Mr. G. C. Champion's Revision of the Mexican 



specimen figured by Gorham is a female, not a male as 

 stated. A Lyciform insect, very like some of the species 

 placed by him under Silis, e. g. S. lycoides, varians, etc. 

 It is perhaps nearest allied to D. purpurascens, which has 

 broader tarsi, red elytra, etc. The male from Coahuila, 

 Mexico, quoted on p. 288 of the " Biologia," which cannot 

 now be found, must have belonged to a difierent species. 



51. Discodon cardinale, n. sp. (Plate III, fig. 3, (J.) 



Elongate, narrow (cj), broader ($), opaque, thickly pubescent; 

 black, the sides of the head in front, the base of the mandibles, 

 and the tarsal claws testaceous or rufo-testaceous, the prothorax 

 (a narrow median vitta excepted) and elytra (except along the 

 sutural margin anteriorly) brick-red, the vestiture of the latter 

 similarly coloured. Head rather small, obliquely narrowed behind 

 the eyes, the latter prominent ; antennae about reaching the middle 

 of the elytra, very broadly dilated from joint 3 in both sexes, 7-11 

 rapidly narrowing outwards. Prothorax (o) transversely sub- 

 quadrate, very gradually narrowed from the base forwards, and 

 with the margins shallowly notched at about the basal fourth; 

 (9) broader, more rounded at the sides, and more rapidly narrowed 

 from the base, the margins conspicuously hollowed at the basal 

 fourth. Elytra long, a little wider than the prothorax, broader in 

 9, flattened on the disc, faintly tricostate, the sculpture hidden by 

 the vestiture. Inner claw of anterior tarsi broadly lobed, and outer 

 claw of the other tarsi cleft at tip, in (^. 



(J. Eighth ventral segment oblong, narrowed outwards, rounded 

 and cleft in the middle at the apex, two stout hooks projecting from 

 the internal sac. 



Length (excl. head) 7|-9-|-, breadth 2^-31 mm. {<$ ?•) 



Hab. Mexico, Atoyac in Vera Cruz [H. H. Smith). 



One pair. A Lyciform insect related to the Costa Rican 

 D, purpurascens, Gorham, but much smaller and narrower, 

 and with the antennae as broadly dilated in both sexes 

 as in various species placed by that author under Silis, 

 e. g. S. serrigera, plateroides, etc. These latter are here 

 placed under Discodon, their respective males having one 

 of the claws of the intermediate and posterior tarsi cleft. 



52. Discodon subulicorne, n. sp. (Plate III, fig. 4, ^.) 



Moderately elongate, widened posteriorly, rather dull, finely 

 pubescent; nigro-piceous or black, the sides of the head in front.
