and Central American Telejphorirme. 53 



cj. Eighth ventral segment rapidly narrowed outwards, the apex 

 narrow and cleft at the middle. 



Length (excl. head) 74-8|, breadth 2f-3J mm. {^ ?.) 



Hah. Mexico, Chilpancingo in Guerrero {Hoge, H. H. 

 Smith), Cuernavaca in Morelos (Hoge). 



Eight males and five females, varying a little in the 

 colour of the legs and apices of the elytra, according to the 

 development of the black portions of the surface. D. rvfipes, 

 from Oaxaca, is a nearly allied form. 



44. Discodon nigripes. 



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

 p. 80. 



Elongate, a little widened posteriorly, shining, clothed with rather 

 long pubescence, this being conspicuous at the sides of the pro- 

 thorax in cj ; reddish-ochraceous or testaceous, the antennae, eyes, 

 legs, and under surface, and the head in great part or entirely in 

 the Mexican examples, black. Eyes large in cj, smaller in $. An- 

 tennae long and slender. Prothorax transverse, the margins with 

 a narrow oblique notch at about the middle in ^J; broader and 

 simply sinuate at the sides in $. Elytra elongate, wider than 

 the prothorax, somewhat widened posteriorly, distinctly costate. 

 Inner claw of anterior tarsi with a broad triangular lobe, and outer 

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



Var. a. Prothorax with an abbreviated median vitta, and the 

 elytra with a common, broad, gradually narrowed, sutural stripe 

 extending from the base to near the apex nigro-piceous, the head 

 wholly black. 9- 



cJ. Ninth ventral segment narrow, produced in the middle at 

 the apex, two stout hooks visible within the internal sac. 



Hab. Mexico, Tepetlapa and Chilpancingo in Guerrero 

 {H. H. Smith), Cuernavaca in Morelos {Hoge, H. H. Smith), 

 Capulalpam and Panistlahuaca in Oaxaca (Salle) ; Guate- 

 mala, Las Mercedes [type], Volcan de Atitlan {Cham,pion). 



A good series of this species is now available for examina- 

 tion, including numerous specimens from Mexico, one of 

 which was labelled (but not quoted) by Gorham. The 

 black legs and under surface, the position of the pro- 

 thoracic notch, and the form of the anterior tarsal claws 

 of the male, separate D. nigripes from D. incisum,. The 

 variety is represented by a single example from Panistla- 

 huaca. A wholly testaceous female from Oaxaca (Salle) 

 may belong here.
