Longicorn Goleopfera of the West India Islands. 85 
22. Prosternodes oherthiiri, sp. n. (PI. 11.^ fig. 1.) 
Thickly and strongly punctured, pitchy-black, with a marginal 
and a broader medio-dorsal longitudinal band on each elytron, 
yellowish-testaceous, Prothorax with two strong dorsal ridges 
between which lies a deep median furrow; with the lateral margins 
in both sexes somewhat parallel, only slightly convergent an- 
teriorly, and furnished with a series of very short blunt teeth ; 
with the upperside grossly and closely, but somewhat irregularly, 
punctured over the whole surface in the female, and over the 
dorsal ridges and groove in the male, with each side of the pronotum 
in the latter sex finely rugulose-punctate and opaque, but crossed 
by a polished line which runs obliquely from the middle of the 
dorsal ridge to the postero-lateral angle. The underside of the. 
body is nitid, and is furnished with a few scattered punctures ; the 
coxae, a spot at each side of the mesothorax, a band at the side of 
the metathorax and also one on each side of the abdomen, are 
silky white. The tarsi above are of a reddish-brown colour. 
Antennae dark-brown or reddish-brown in colour. Long. 31-34, 
lat. 9i-ll mm. 
Hah. Haiti (?). The locality from which the male 
type came is unknown. 
In the male type the dorsal band of each elytron 
widens out behind and joins the marginal band^ so that 
the whole apex is yellowish-testaceous in colour. In two 
females seen the bands do not unite at the apex, and the 
dorsal band does not quite reach the base in front. This 
difference, however, is probably individual and not 
sexual. 
I have named this interesting species after M. Bene 
Oberthiir, who has kindly lent me the typesfor examination. 
It offers characters which seem to be somewhat inter- 
mediate between those of Prosternodes and Solenoptera. 
But I have referred it to the former genus because the 
prosternal process is somewhat rounded and not 
emarginate behind ; and the sides of the pronotum are 
less convergent anteriorly than is the case with the 
species of Solenoptera.
