and Central American Telephorinae. 75 



Hub. Mexico, Omilteme and Xucumanatlan in Guerrero 

 {H. H. Smith : (^ ?), Oaxaca {Salle : ($). 



Described from one male and six females from Guerrero. 

 The two males from Oaxaca, left unnamed by Gorham, are 

 smaller and narrower, and have more slender antennae; 

 but there can be little doubt that they belong to the same 

 species, the genital armature being similar. A Lampyri- 

 form insect, with the lateral margins of the prothorax 

 entire in the male. 



4. Polemius nigrolimbatus, n. sp. 



Discodon cleroides, var., Gorh., Biol. Centr.-Am., Coleopt. 

 iii, 2, p. 287 (cJ). 



Rather broad, dull, clothed with fine broAvnish or cinereous 

 pubescence ; black, the base of the mandibles, and a rather broad, 

 anteriorly widened, oblique, submarginal stripe on each side of the 

 prothorax (the two stripes usually connected along the apical 

 margin) flavous. Eyes not prominent. Antennae subserrate, 

 rather stout, tapering towards the tip, short in $, longer in cj. Pro- 

 thorax ample, as broad as or broader than the base of the elytra, 

 subtruncate in front, broadly explanate laterally ; the sides gradu- 

 ally, arcuately converging forwards from near the base, at most 

 very feebly sinuate, without trace of notch in ^. Elytra more or 

 less explanate from a short distance below the base, coriaceous, 

 obsoletely costulate. Inner claw of anterior and outer claw of the 

 other tarsi lobed in (^. 



(^. Ninth ventral segment oblong, gradually narrowed towards 

 the apex, the extruded flagellum acuminate and simply curved. 

 (Fig. 28). 



Length (excl. head) 7^-10, breadth 3-4| mm. {^ ?.) 



Hab. Mexico (Truqid, Salle; Mus. Oxon.), Mexico City 

 {Hoge, H. H. Smith), Toluca {Salle). 



Apparently not rare in the vicinity of the city of Mexico, 

 whence six examples have been received. This species 

 and P. nigromarginatus differ from Discodon cleroides in 

 having the prothorax unnotched and somewhat rounded 

 at the sides in the male, and the tarsal claws otherwise 

 formed in that sex, the head black to the anterior margin, 

 and the prothorax relatively very broad in both sexes. 

 The less rounded sides of the prothorax and the broader 

 yellow submarginal stripes separate P. nigrolimbatus from 

 P. nigromarginatus.
