ENOALUS n. g. 



This genus also resembles a small Erirldnus, and differs from Proctorus 

 only by the beak being longer than the prothorax, and more slender; it is 

 also punctured and feebly striate towards the base, as in many Anthofioini. 

 The antennae are inserted about one-fourth from the end of the beak; the 

 scape almost reaches to the eyes, which are moderate in size and distant; 

 the funiculus is 7-jointed, first joint longer, the others nearly equal, short, 

 gradually wider and more rounded; club oval, annulated; ventral segments 

 unequal, third and fourth together as long as second, fifth nearly as long; 

 first suture straight; others angulated at the sides. Legs moderate, thighs 

 armed with a small tooth; claws divergent, broadly appendiculate. 



1. E. decipiens n. sp. 



Black, clothed with white and yellowish pubescence. Prothorax not 

 wider than long, broadly rounded on the sides, coarsely and very deeply 

 punctured. Elytra wider than prothorax, at base elongate oblong, with a 

 broad transverse black band occupying the middle third; stri* coarsely 

 punctured, interspaces flat. Antenn« and legs piceo-ferruginous. Length 

 3.4 mm.; .13 inch. 



Illinois and Minnesota; two specimens. In form and color this insect 

 bears an almost deceptive resemblance to Macrops solutus, but in other 

 characters it is in every way different. 



PLOOETES n. g. 



Beak rather stout, as long as the prothorax, carinate, punctured and with 

 three fine elevated lines each side; antennal grooves deep, extending to the 

 lower margin of the eyes, which are oval and rather large. Antennae in- 

 serted about one-fourth from the tip, scape reaching nearly to the eyes; 

 funicle 7-jointed, first joint as long as the three following united and 

 stouter; second a little longer than third; 3-7 equal, scarcely increasing in 

 width; club elongate-oval, annulated, rather large. Prothorax scarcely 

 wider than long, rounded on the sides, narrowed in front of the middle, 

 neither lobed nor constricted in front. Elytra one-half wider than protho- 

 rax, humeri oblique and rounded, disc not very convex, posterior callus 

 rather prominent. Abdomen rather flattened; first ventral suture straight; 

 the others distinctly angulated near the sides; third and fourth segments 

 very little shorter than the first and second; fifth about one-half longer than, 

 fourth; pygidium covered. Legs rather -stout, thighs clavate, with a very 

 small tooth beneath, tibiae broadly sinuate on the inner side; terminal hook 

 distinct; tarsi with third joint bilobed, claws with a long, slender tooth, not 

 bent inwards. 



1. P. ulrai n. sp. 



Black, clothed with small brown scaly hairs; beak carinate, striate and 

 punctured, head punctured. Prothorax densely and deeply punctured, with 

 a smooth, slightly elevated dorsal line. Elytra with a transverse band be- 

 hind the middle, of white pubescence, which is longer and more dense near
