third. Elytra at the base slightlj^ wider than the prothorax, some- 

 what explanate from a little below the shoulder, rather coarsely 

 sculptured. Tarsi dilated, the anterior pair broader in ^ ; inner 

 claw of anterior pair broadly lobed, and outer claw of the others 

 cleft, in cj. 



(5*. Eighth ventral segment emarginate in the middle at the apex, 

 the latter appearing broadly bilobed ; internal sac, as seen partially 

 evaginated, disclosing a long, acute, backwardly projecting spine 

 on each side, and various other slender spines in the centre. (Fig. 

 19.) 



Hah. Costa Rica. 



Redescribed from the types, the male, as stated by 

 Gorham, being discoloured and completely abraded, the 

 female, on the contrary, is in perfect condition. The 

 wholly black legs and antennae, the basally widened pro- 

 thorax of the female, and the genital armature of the 

 male, separate B. purpurascens from D. calidnm. The 

 female might easily be mistaken for a Lycid ; it has the 

 elytral pubescence scarlet. 



50. Discodon histrio. 



Discodon histrio, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, 

 p. 86, pi. 5, fig. 22 ($, not $ as quoted) {nee p. 288). 



Moderately elongate, widened posteriorly, shining, finely pubes- 

 cent; black, some markings on the front of the head, the base of 

 the mandibles, the sides of the prothorax broadly, and an elongate 

 humeral patch on the elytra, ochreous or rufo-testaceous. Eyes 

 rather small, a little larger and prominent in ^. Antennae moder- 

 ately long, subserrate, tapering towards the tip. Prothorax (o) 

 subquadrate, arcuate in front, obliquely notched on each side at 

 the middle; ($) broader and more transverse, the sides sinuate and 

 converging from near the base. Elytra considerably wider than 

 the prothorax, widened from a little below the shoulder, rugosely 

 punctured and distinctly costate. Inner claw of anterior tarsi 

 broadly lobed, and outer claw of the other tarsi cleft, in ^. 



Q. Eighth ventral segment oblong, narrowing outwards, rounded 

 and notched in the middle at the apex, the dorsal portion of the 

 same segment short, broadly bilobed at the tip, two stout hooks 

 projecting from the internal sac. (Fig. 20.)
