AKT. 9 WEST INDIAN BUPRESTIDAE FISHER 76 



the insertion of the antennae ; epistoma short and arciiately emargi- 

 nate in front ; antennal cavities large, deep, rounded, and situated 

 about equalh^ distant between the anterior margin of epistoma and 

 the inner margin of the eyes. Antennae rather robust, and nearly as 

 long as the head and pronotum united ; first joint moderately elongate 

 and strongly clavate at apex ; second very short and globular ; third 

 slightly shorter than the first, but more slender and cylindrical ; fol- 

 lowing joints longer than wide, more obtusely dentate on the inner 

 side, and becoming gradually shorter to the eleventh joint, which is 

 oblong, the serrate joints armed with poriferous pores on both sides 

 of the joints, but without distinct foveae. Eyes not very large, mod- 

 erately convex, broadly oblong, and only slightly closer to each other 

 on the vertex than at the front. Pronotum wider than long, moder- 

 ately convex, and longitudinally sulcate or carinate at the middle; 

 base bisinu'ate. Scutellum very small and nearly quadrate. Elytra 

 elongate, sinuate at base, moderately convex, and strongly attenuate 

 posteriorly ; lateral margins more or less serrate posteriorly. Sternal 

 cavity formed by the mesosternum and metasternum; mesosternum 

 divided, the lateral branches long 'and oblique; metasternum feebly 

 rounded in front and with a narrow longitudinal groove at the 

 middle. Presternum feebly convex; anterior margin sinuate and 

 feebly produced at middle; prosternal process wide, flat, and with 

 two longitudinal sulci. Posterior coxae strongly dilated internally; 

 'anterior margin sinuate; posterior margin strongly oblique. Legs 

 rather robust; anterior and middle femora strongly swollen at mid- 

 dle, the posterior pair subcylindrical ; tibiae subcylindrical, feebly 

 enlarged at the apex, and the anterior pair with a longitudinal carina 

 on the exterior m'argin; tarsi depressed, elongate, the first joint of 

 the posterior pair as long as the following two joints united. First 

 abdominal segment concave or sulcate at middle. Body robust, 

 elong'ate-oval, attenuate in front, and more acuminate behind. 



This genus is distributed throughout the Nearctic and Palae'arctic 

 Kegions, and includes about 20 described species, of which only two 

 have been recorded from the West Indies. One of these was origi- 

 nally described from Guadeloupe, and the other was introduced into 

 Cuba, probably in pine timber from the United States. The species 

 are closely allied, but the following table, which is taken from Ker- 

 rem'ans Monograph, may be of some assistance in separating the two 

 species. 



KEY TO THE SPECIES 



Elytra with the subsutiu-al groove entire, attaining the base, though shallow 

 and sometimes partially interrupted near the base; color above reddish- 

 cupreous; sulcus on first abdominal segment pubescent, more distinctly in 

 the male humboldti (Castelnau and Gory).
