CANTHARIS, 443 
Four examples, one only of which is of the male sex. This insect nearly agrees with 
Dr. Horn’s description of C. melena, Lec. (Proc. Am. Phil. Soc. xiii. p. 105), from 
Sonora and Arizona; but C. melena, 3, has the last dorsal segment acutely oval at 
tip, and the sixth ventral segment deeply emarginate. 
10. Cantharis ebenina. 
Cantharis ebenina (Chevr.), Dugés, La Naturaleza, iv. p. 66, t. 2. figg. 10, 10a—c (1877)*; An. 
Mus. Michoacano, i. p. 103°. 
Lytta ebenina (Chevr.), Dej. Cat. 3rd edit. p. 246°. 
Hab. Mexico ? (Boucard 1), State of Vera Cruz (Boucard?), Boca del Monte (Flohr 2), 
Matamoros Izucar, San Andres Tuxtla (Sallé), Esperanza (Hége). 
Found in abundance by Herr Hoge at Esperanza. ‘This insect is of a uniform dull 
black colour; the head and thorax are very finely, sparsely, irregularly punctate, the 
disc of the latter almost smooth; the elytra are very finely scabrous-punctate; the 
outer spur of the hind tibiz is moderately stout, the inner one slender. The male has 
joints 4-6 of the antenne a little thickened and the sixth ventral segment feebly 
emarginate. 
C. ebenina is closely allied to C. tenebrosa, Lec., from California, but is smaller and 
less elongate, and has the head and thorax much more finely punctured and the elytra 
smoother ; the sixth ventral segment is feebly emarginate in the male in both species. 
Varies in length from 7-15 millim. 
11. Cantharis plumbea. 
Lytta plumbea (Klug), Haag, Berl. ent. Zeitschr. 1880, p. 38°. 
Hab. Mexico (coll. Haag*), Canelas in Durango (Becker). 
‘ Elongata, opaca, obscure eenescens ; capite dense punctato, postice canaliculato; thorax rugulis minutissimis 
opaco, sat grosse punctato, antice posticeque impresso, canaliculato, utrinque fovea distincta impressa ; 
elytris latis, humeris distinctis, rugulosis. Long. 12-18, lat. 4-44 millim.” 
Six examples from Durango agree very nearly with this diagnosis. They are dull 
black, with a slight brassy lustre ; the head and thorax coarsely, rugosely punctate, the 
latter transverse, somewhat rounded at the sides, transversely depressed anteriorly, and 
with a depression on either side of the disc behind ; the elytra finely scabrous-punctate, 
flattened on the disc, and vaguely sulcate towards the base; the antenne stout, with 
joints 4-6 a little thickened in the male; the outer spur of the hind tibiee moderately 
stout, the inner one slender. The male has the fifth ventral segment broadly and 
shallowly, the sixth very deeply, emarginate. 
12. Cantharis bipuncticollis. (Tab. XX. figg. 21, ¢; 21a, sixth ventral 
segment, ¢.)
