sparsely and finely punctured head and thorax, the latter being more elongate, 
distinguish it at a glance. In the emarginate base of the thorax it resembles 
C. biguttata.

Hab. Mexico!, Pénjamo in Guanajuato (Sallé, Dugés), Gardidueiia (Dugés*), Chil- 
pancingo (Flohr, Hoge, H. H. Smith), Tierra Colorada, Acaguizotla, Hacienda de la 
Imagen, Venta de Pelegrino, all in Guerrero (H. H. Smith), Tonila in Colima, Tacam-

We have received about seventy examples of this variable species, including a pair 
still “in copula” from Herr Hoge (from Matamoros Izucar), whereof the male belongs 
to C. sobrina and the female to C. bipartita, Dugés. Haag! enumerates five colour- 
varieties of this insect, specimens of all of which are before me, including some deter- 
mined by himself; these are as follows :—(1) Tota nigra, interdum obscure enescens, 
puncto capitis rufo (=sobrina, Dugés) ; (2) Thorace rufo, bipunctato ; (3) Capite rufo, 
ante oculos nigro-bipunctato, thorace rufo, bipunctato; elytris rufis, apice nigris (=07- 
partita, Dugés) ; (4) Idem, sed capitis nigrescente, rufo-punctato ; (5) Idem, sed humeris 
solis rufis. ‘The head and thorax are coarsely punctured, the latter as long as broad 
and with a smooth spot on either side of the disc about the middle; the antenne are 
gradually thickened to the tip in both sexes, moderately long in the male, shorter in 
the female; the elytra are rather coarsely scabrous-punctate ; the outer spur of the hind 
tibie is broad, the inner one slender. In the male the fifth ventral segment is broadly, 
and the sixth segment very deeply and acutely, emarginate, the lateral processes of the 
sixth elongate. 
We figure two varieties, of which one (fig. 23) belongs to C. bipartita, Dugés. 
23. Cantharis gentilis.
