A New Cerambycid Beetle from Santo Domingo (Col.). 



By W. S. FISHER, U. S. Bureau of Entomology. 



Among a small collection of West Indian Cerambycidae re- 

 ceived from Mr. J. J. Davis for identification, the following 

 apparently new species was found. 



Callichroma domingoensis new species. 



$ . Elongate, subcylindrical and attenuate posteriorly; head, pro- 

 notum, elytra and underside except abdomen dull metallic green with a 

 slight violaceous tinge ; antennae, tibiae, tarsi and abdomen black ; femora 

 entirely of a bright reddish-brown color, and somewhat opaque. 



Head deeply longitudinally grooved on vertex. Antennae about one 

 and one-half times as long as the entire body; joints three to eleven 

 strongly, longitudinally carinated. 



Pronotum with the medio-lateral tubercle well developed and acute at 

 tip; antero-lateral callosity not strongly marked; strongly constricted 

 anteriorly and along the base, the basal constriction being more shallow 

 than one along anterior margin ; disc on each side of median line with a 

 feebly rounded gibbosity just behind the anterior constriction; surface 

 strongly, transversely rugose, with a few distant punctures between the 

 rugae, and sparsely clothed with short black hairs. Scutellum large, tri- 

 angular, and longitudinally concave; surface smooth at middle and 

 rather densely, finely punctate towards the sides. 



Elytra two and one-half times as long as wide; sides very much nar- 

 rowed from base to tips, which are rather broadly separately rounded ; 

 humerus well developed; surface rather deeply, densely and confluently 

 punctate, becoming feebly rugose towards apex, and sparsely clothed 

 with very short, inconspicuous, recumbent black hairs. 



Abdomen rather densely, obsoletely punctate and densely clothed with 

 a short, somewhat silvery pubescence ; last ventral segment broadly 

 rounded at apex without any trace of a notch. 



Front and middle femora short and abruptly petiolate near apex ; hind 

 femora slender, compressed, gradually becoming wider to apex and 

 reaching to the tip of the elytra. Front and middle tibiae about equal in 

 length to the femora, slightly compressed and gradually enlarged anter- 

 iorly; surface longitudinally carinate, finely, irregularly punctate and 

 clothed with long stiff black hairs. Hind tibiae not quite as long as the 

 femora, moderately broad and strongly compressed ; lower surface 

 broadly concave with the inner margin densely clothed with a series of 

 stiff black hairs. 



Length 28 mm. ; width 8 mm. 



Type Locality. "San Sidro, Santo Domingo." Type. Cat. 

 No." 24676, U. S. National Museum. 



Described from a single male specimen received from Mr. 

 J. J. Davis, and collected by Dr. Browne during April or May, 

 1919, at "San Sidro, Santo Domingo." [San Isidro?]. 



This species resembles Callicliroina plicaturn LeConte, to a 

 certain extent, but is, however, easily separated from that 

 species by the abdomen being entirelv Mack, pronotum less 

 densely punctured, and the femora being uniformly light red- 

 dish-brown in color, and not tipped with black as in plica f it m.
