arcuate. Ungues rather long, completely connate and without 

 suture in rather less than basal half. 



This wonderful genus is entirely without near relatives within 

 our faunal limits. The slender beak abruptly dilated at base and 

 subvertical mandibles remind us of Eunyssobia, but the dilated 

 third tarsal joint and connate claws, deeply sulcate prosternum and 

 general habitus of the body, depart very widely from that genus 

 and show that it must be considered an intermediate and remark- 

 ably synthetic type. 



At SUllUlirostris n. sp. — Oval, shining, coarsely sculptured, piceous- 

 brown in color throughout. Head finely but strongly, rather closely punctate, 

 scarcely visibly, broadly impressed between the eyes and with a small inter- 

 ocular fovea. Prothorax nearly two-thirds wider than long, the sides broadly, 

 evenly arcuate, becoming nearly parallel in basal half, strongly convergent 

 but very feebly constricted toward apex, the latter less than one-half as wide 

 as the base, which is transverse and straight, with the median lobe rather 

 narrow but strong, abrupt and rounded ; disk coarsely punctate, the punc- 

 tures contiguous laterally but smaller and slightly separated toward the ill- 

 defined median impunctate line. Scutellum small, subquadrate, flat, roughly 

 sculptured. Elytra, at the moderately developed humeral callus, distinctly 

 wider than the prothorax, about three- fourths longer than the latter, scarcely 

 as long as wide, broadly hemi-elliptical in outline ; striae coarse, deep, finely 

 and remotely punctate at the bottom, the intervals flat, twice as wide as the 

 striae, extremely coarsely roughly and unevenly but not very deeply punctate, 

 polished. Under surface densely punctate, the metasternum very coarsely 

 so, the abdomen more finely, and with small sparsely distributed squamules 

 throughout. Length 3.0 mm. ; width 1.7 mm. 



Texas. 



The upper surface has a few widely scattered slender squamules 

 toward the sides of the pronotum and along the elytral intervals, 

 more conspicuous at the base of the second. A single specimen. 



The following is interesting as being the second known species 

 of Madarellus thus far discovered in the United States : — 



M. ClineatllS n. sp. — Strongly convex and cuneiform, highly polished, 

 black throughout. Head finely but strongly, sparsely punctate, the trans- 

 verse impression distinct and broadly angulate in profile ; beak stout, evenly 

 arcuate, gradually and feebly tapering from base to apex, rather longer than 

 the prothorax, somewhat coarsely deeply and moderately densely punctate 

 throughout, with a median impunctate line ; antennae inserted at basal third, 

 the scape short, scrobes deep, basal joint of the funicle elongate, club cylindro- 

 ovoidal, subequal in length to the five or six preceding joints, densely opaque 

 and pubescent. Prothorax large, one-half wider than long, inflated, widest
