joints 4-6 of the antenne are slightly thickened. C. cyanescens also differs from C. koltzez 
by its cyaneous or greenish colour, and by the more shining, less closely punctured head 
and thorax, the latter less transverse. Six males and two females of C. cyanescens 
are before me. 
15. Cantharis humilis. 
Lytia humilis, Haag, Berl. ent. Zeitschr. 1880, p. 39°. 
Hab. Panama (coll. Haag 1). 
‘* Klongata, opaca, cyanescens vel enescens, interdum brunnescens; capite thoraceque rude punctato, hoc 
transversim ruguloso, antice posticeque impresso ; elytris elongatis, attenuatis, rugulosis, pilis decumben- 
tibus albidis tectis. Long. 8-10, lat. 2-24 millim.” 
This species is said to be closely allied to C. koltzei ; we have not received a specimen 
of it. Apparently described from a single female example. 
16. Cantharis subviolacea. 
Cantharis augusti, Deyr. in litt. 
Moderately elongate, obscure violaceous, the head and prothorax of a more neous tint, sparsely pubescent, 
shining, the elytra opaque. Head sparsely, rather coarsely punctate, the eyes large; antenne short and 
stout in both sexes, thickening outwardly, the joints moniliform; prothorax transverse, narrowed before 
and behind, canaliculate in the middle, the sides, base, and apex very sparsely and rather coarsely punc- 
tate, the disc almost smooth; elytra finely scabrous-punctate ; beneath sparsely, finely punctured ; the 
outer spur of the hind tibiz stout, the inner one slender. 
3. Antenne with joints 4 and 5 a little thickened; sixth ventral segment very deeply, subtriangularly 
emarginate. 
Length 7-15 millim. (¢ 9.) 
Hab. Mexico, Parada, Duraznal (Sal/é 1). 
One male and three female examples. This is the species mentioned by Haag, Berl. 
ent. Zeitschr. 1880, p. 38, nota, under the name of Lytta variabilis, Dugés, var. augustt, 
Deyr. C. subviolacea, however, has the sixth ventral segment very deeply emarginate 
and the fourth and fifth antennal joints slightly thickened in the male. It also differs 
from C. variabilis in the much more finely and sparsely punctured head and thorax, and 
in its violaceous colour.

In the typical form of this variable species the elytra have each an oval spot at about
