and Central American Telephorinae. 45 



Var. o. Elytra and abdomen (the apical margin of each segment 

 excepted) black or piceous, the tibiae testaceous at the base. $. 



Discodon erosimi, Gorh., Biol. Ceiitr.-Am., Coleopt. iii, 2, 

 p. 285 (?) {nee p. 79). 



(J. Eighth ventral segment long, bluntly rounded and cleft in 

 the middle at the tip; ninth segment long, broadly sub-bilobed at 

 the apex, two pairs of stout hooks projecting from the internal 

 sac (figs. 11, 11a). 



Length (excl. head) 10, breadth 3^4 mm. (^J $.) 



Hab. Costa Rica, Cariblanco in Sarapiqui {Biolley : 

 types, (^ $) ; Panama, Volcan de Chiriqui {Champion : $, 

 var.). 



Described from the pair from Costa Rica ; the female 

 with black elytra referred to D. erosum by Gorham in his 

 " Supplement " almost certainly belongs to the same 

 species. D. hiolleyi approaches D. plicatum and D. strami- 

 neicolle; the male has the anterior tarsal claws differently 

 formed from those of D. erosutn, and the prothoracic notch 

 placed further forward. 



34. Discodon vitticolle.

Rather narrow (o), broader and with the elytra somewhat ex- 

 planate ($), shining, clothed with fine pallid pubescence ; fuscous 

 or nigro-fuscous, the head on each side in front, and sometimes the 

 epistoma also, the base of the mandibles, the prothorax (an in- 

 complete median vitta, often widened posteriorly, excepted), the 

 elytra with a humeral spot or streak — in some specimens continued 

 obliquely down the disc to near the inner apical angle — and usually 

 the suture and outer margin also, the femora and the tibiae in part 

 or entirely, stramineous or testaceous. Antennae slender, long, 

 sparsely pilose, shorter in $. Eyes large and prominent in ^, 

 smaller in $. Prothorax with the sides angularly notched at or 

 just behind the middle in ^, simply sinuate in $. Elytra a little 

 wider at the base than the prothorax. Inner claw of anterior tarsi 

 broadly lobed, and outer claw of the other tarsi cleft at the tip, 

 in cJ. 



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

 thus appearing broadly bilobed ; ninth segment gradually narrowed
