ECTOPEIA.— ETJCINETUS, 599 



at the tip, acutely serrate from the fifth joint, joint 3 elongate, longer than 4, 5 shorter than 4, 5-10 

 about equal in length. Prothorax very short, more than twice as broad as long, rapidly and arcuately 

 narrowing from the base forwards, emarginate in front and feebly bisinuate at the base, the lateral 

 margins reflexed, the hind angles sharp ; the surface with short, sinuous, irregular, depressed, anastomosing 

 lines of very fine punctures, the interspaces between which are densely, excessively minutely punctate, 

 the disc depressed on either side of the middle at the base. Elytra feebly rounded at the sides, some- 

 what obliquely narrowing behind, and rather abruptly declivous from about the middle ; sculptured like 

 the prothorax, but with the short sinuous anastomosing lines of punctures deeply impressed and very 

 conspicuous, and the very minute dense punctuation of the interspaces more distinct. 

 Length 3|, breadth 2^ millim. 



Hob. Panama, Bugaba (Champion). 



One example. In this insect the short, sinuous, anastomosing lines of punctures 

 on the elytra are much more deeply impressed than in any of the species of Dicrano- 

 pselaphus.

A holarctic genus containing sixteen described species *. The single representative 

 from Guatemala is closely allied to various North- American forms. These insects 

 show a remarkable resemblance to the genus Orchesia and other Melandryidse, and also 

 to the Mordellidee, in the form of the middle and hind legs. Reitter places Eucinetus 

 in the Clavi corn-series, near C Iambus. 



1. Eucinetus strigipennis. (Tab. XXVI. fig. 18 f.) 



Navicular, convex, shining ; black or blackish-brown, the head and prothorax ohscure castaneous : the antenna? 

 with the basal three joints testaceous, the apical one or two joints yellow, and the others black or slightly 

 infuscate ; the palpi testaceous ; the legs obscure ferruginous, with the tip of each of the joints 1-4 of 

 the four hinder tarsi, as well as the extreme apex of the hind tibiae, black, and the anterior tarsi, and the 

 apical joint of each of the other tarsi, testaceous ; thickly clothed with very fine, sericeous, brownish 

 pubescence. Head densely, very minutely punctate ; antenna? moderately long, very slender, a little 

 thickened at the tip, joints 1 and 2 stouter than the others, 2 slightly longer than 1, 3 and 4 each nearly 

 as long as 2, 5-10 decreasing in length, 10 not much longer than broad, 11 oval. Prothorax more 

 shining than the elytra, sparsely and less distinctly punctured than the head, the punctuation excessively 

 minute. Elytra closely, transversely strigose, with a series of fine shallow longitudinal grooves, the inter- 

 spaces between which appear to be slightly convex, and a well-marked sutural stria, extending from the 

 apex to before the middle. Posterior tibiae with a single long spur. 



Length 3-3|, breadth If— lg millim. 



Ilab. Guatemala, Cerro Zunil and San Geronimo (Champion). 



One specimen from each locality, probably females. The example from Cerro Zunil 

 differs from the other in being less elongate; it also has the intermediate joints of the
