AKT. 9 WEST INDIAN BUPRESTIDAE FISHER 195 



elongate, lobed at base, apex rounded or acuminate; humeri promi- 

 nent. Sternal cavity formed by the metasternum, and mesosternum, 

 the former arcuately emarginate in front. Mesosternum divided, 

 the lateral branches short and scarcely visible. Prosternum Avide in 

 front, attenuate behind, and the anterior margin with a distinct lobe. 

 Middle coxae not more widely separated than the anterior ones. 

 Posterior coxae short, slightly dilated internally, narrowest at mid- 

 dle, and strongly dilated anteriorly at the lateral margin. Abdomen 

 not distinctly visible from above, first and second segments united. 

 Legs slightly robust ; femora fusiform, the anterior and median ones 

 dentate on the inner margin ; anterior and median tibiae feebly arcu- 

 ate, the posterior ones straight ; tarsi more or less elongate and com- 

 pressed, the joints armed with distinct lamellae, first joint of pos- 

 terior pair as long or longer than the following three joints united; 

 tarsal claws dentate, appendiculate or bifid. Body oblong, elongate, 

 and slightly attenuate posteriorly. 



Waterhouse has erected this genus for Agrilus frontalis Castelnau 

 and Gory, and allied species, which differ from Agrilus in having 

 the basal joint of the posterior tarsi comparatively short, but this 

 seems to be a variable character as intermediate forms exist, and in 

 a large series of species the two genera will run together. Kerre- 

 mans is his classification of this family has retained Paradomorphus 

 as a valid genus for the species having the anterior and middle 

 femora finely dentate on the inner margin. 



The species of this genus is Avidely distributed throughout Mexico, 

 Central America, and the northern part of South America, but so 

 far only one species has been found in the West Indies.

Paradomorphus alMcollis Waterhouse, Trans. Ent. Soc. London, 1887, 

 p. 184. 



Elongate, broadly rounded in front, feebly attenuate behind, and 

 only slightly narrower behind than in front, subopaque ; head black, 

 with bluish and cupreous reflections; pronotum entirely covered 

 with a dense white tomentose, which conceals the surface sculpture; 

 elytra piceous, cyaneo-aeneous at base, more strongly aeneous at 

 lateral sides near middle, and with strong cyaneous reflections pos- 

 teriorly; each elytron ornated with cinerous pubescence as follows: 

 Three small irregular spots on the disk, the spots arranged in a 

 straight line between the suture and longitudinal costa, the first 

 rather obsolete just behind the scutellum, a larger one at basal third, 

 and a similar one just behind the middle, there is also a narrow zig- 

 zag fascia at apical third extending from the lateral margin slightly 

 forward, then turning obliquely backward, and finally a little trans- 

 verse, but not reaching the suture ; there is also a broad white tomen-
