Described from seven examples, probably all females except one; 

 all collected at the type locality during February and May, by E, 

 A. Schwarz. 



This is the smallest known species of this genus and on account 

 of the rounded sides of the pronotum should probably be taken as 

 the type of a new genus, but until a revision is made of the entire 

 tribe, it is advisable to retain it in the present genus. 



LEIOPUS CUBANUS, new species 



Male. — Form less elongate and more oval than atrovittatus Fisher ; 

 above reddish-brown, rather densely clothed with cinereous and 

 brownish-yellow pubescence, and ornamented with more or less dis- 

 tinct, irregularly placed black markings; beneath reddish-brown, 

 with the abdomen more yellowish, and the basal part of the femora, 

 apex of tibiae, and tarsi black. 



Head slightly transverse and nearly flat in front, slightly concave 

 between the antennal tubercles, which are feebly elevated and widely 

 separated, the surface densely clothed with cinereous and brownish- 

 yellow pubescence, giving it a mottled appearance and concealing 

 the punctuation, and with an obsolete, longitudinal groove extend- 

 ing from the epistoma to occiput; eyes rather coarsely granulated, 

 deeply emarginate, and separated from each other on the top by 

 about the width of the emargination of the eyes in front, the lower 

 lobes rounded, and the upper lobes small and narrow. Antennae 

 one and three-fourths times as long as the body, pale rufous or 

 luteous, mottled with cinereous and brownish pubescence, the joints 

 more or less annulated dark brown or black, except the last joint, 

 which is of a uniform black or dark-brown color. 



Pronotum three-fourths wider than long, and slightly narrower 

 at base than apex ; sides feebly arcuately rounded from apical angles 

 to an acute, prominent denticle near the base, behind which they are 

 strongly and abruptly constricted; surface even, with an obsolete 

 narrow transverse depression along the anterior margin, and a 

 broader depression along the base, sparsely, rather coarsely and 

 irregularly punctate, densely clothed with cinereous and brownish- 

 yellow pubescence, which is usually browner on the median parts, 

 and ornamented with tluee or four small black discal spots. 



Elytra thrce-fourtlis longer than wide, and distinctly wider than 

 the pronotum; sides parallel to apical third, then arcuately at- 

 tenuate to the tips, which are feebly obliquely truncate internally, 

 with the exterior angles obtusely rounded; surface uneven, strongly 

 declivous at the sides, but the carina not distinctly marked, the 

 discal lines obsolete, densely and irregularh^ punctate, the punctures 

 in the basal region rather coarse, but becoming finer toward the 

 apex, with numerous, irregularly placed black fasciculi, rather
