Sharp, Biol. Cent. Am., i., pt. 2, p. 59. 



Mexico (Oaxaca). 



In this species also the legs are yellow. It is closely 

 allied to H. ocliripes, Curt., but is of more elongate and 

 narrow form, the punctuation of the wing-cases is more 

 distinct, and the sternal spine is shorter, though other- 

 wise similar; the epipleural margin is narrow, and its 

 sculpture on the basal portion obsolete. 



31. Tropistemus lancifer, n. s. 



Niger, parum metallescens, palpis antennarumque basi 

 testaceis, pedibus runs ; latiusculus, minus convexus, 

 capite thoraceque sat fortiter, elytris parce subtilissime 

 punctatis ; margine pleurali antice lsevi, ad medium 

 parce parum distincte punctato ; spina sternali elongata, 

 tenui ; abdominis apice carina obscura sed ad mar- 

 ginem posteriorem distincte elevata. Long. 10 — 11 mm., 

 lat. 5£ mm. 



Colombia. 



Punctuation of head and thorax quite distinct and not 

 close, their systematic punctures deeply impressed, those 

 on the side of the thorax forming a short line ; wing- 

 cases sparingly and extremely finely punctulate ; the 

 epipleural margin is not punctate at the base, behind 

 the middle it is narrow, and bears not very distinct 

 distant punctures. The legs are elongate and slender ; 

 the sternal spine is elongate and slender, extending a 

 little beyond the 2nd ventral suture ; on the last ventral 

 segment there is a short carina, which at the apex is 

 distinctly elevated. 



The species is readily distinguished from T. ocliripes 

 by the indistinct punctuation of the epipleural margin. 



32. Tropistemus fuscitar sis, Sharp. 



Sharp, Biol. Cent. Am., i., pt. 2, p. 58. 



Mexico, Guatemala ; Colombia (fide Mus. Castlenau). 



This is a species in which the colour of the legs 

 appears variable. It has the punctuation of the epi- 

 pleurse indistinct, as in T. lancifer, but is readily dis- 

 tinguished from that species by the shorter, more depla-
