COLEOPTERA. 1G1 



7. A. lliegalops n. sp. — Form slender, sub-cylindrical ; sides behind 

 the head nearly parallel. Pubescence very sparse, more plentiful on the 

 abdomen, piceo-cinereous, inconspicuous. Head very large, twice as wide as 

 long ; interocular surface very feebly depressed, not twice as wide as the eye ; 

 sulcations rather feeble ; intermediate surface slightly wider than the lateral 

 portions, moderately and evenly convex ; punctures coarse, deeply impressed, 

 rather close and evenly distributed ; interspaces very convex, highly polished ; 

 ocular lines meeting at two lengths in advance, very feebly convergent ; 

 antennae distinctly longer than the width of head, translucent, piceo-testa- 

 ceous, nearly black toward the base, slender, club moderate ; joints nine, 

 ten. and eleven increasing rapidly in width and length, slender; maxillary 

 palpi 'rather long and slender, flavo-testaceous, darker toward the base, very 

 translucent. Prothorax arcuately, evenly, and rather rapidly increasing in 

 width to fhe middle, where it is much narrower than the head and slightly 

 narrower than long ; sides thence moderately convergent posteriorly and 

 feebly sinuate ; anterior and posterior margins equal in length and curva- 

 ture, moderately arcuate ; surface feebly and narrowly tuberculate at a short 

 distance from each basal angle, also longitudinally canaliculated ; punctures 

 coarse, irregularly distributed, not crowded, deeply impressed; interspaces 

 convex, polished ; canaliculation rather feebly impressed, bottom rounded, 

 fusiform in shape, nearly as long as the pronotum. Elytra at base much 

 narrower than the pronotum, equal to the width of the latter at base ; sides 

 very strongly divergent posteriorly, longer than the width at base, very 

 strongly and evenly arcuate ; together broadly, roundly, and strongly emar- 

 ginate behind ; suture distinctly shorter than the pronotum ; surface not 

 appreciably impressed along the suture ; coarsely, rather evenly, and some- 

 what distantly punctate ; interspaces wider than the punctures, convex and 

 polished. Abdominal segments as wide as the contiguous elytra ; scarcely 

 perceptibly decreasing in width ; border extremely narrow, rather depressed 

 than reflexed ; surface convex, very highly polished, deeply, somewhat finely 

 and evenly punctate ; transverse carinae not cusped ; lateral spiracles very 

 distinct. Legs pale piceous-brown, slender ; first joint of the posterior tarsi 

 as long as the next three together ; fourth joints narrowly bilobed. 



Male. — Sixth ventral segment narrow at apex, where it is sinuate, sinus 

 occupying the entire apex, evenly rounded, very feeble ; seventh roundly 

 emarginate at tip, toothed laterally. 



Female. — Sixth segment evenly rounded behind. 



Length 3.6-4.0 mm. 



Crescent City, Florida, 10. 



This species is remarkable for its very large head and the peculiar 

 structure of the elytra; it should, perhaps, be placed in a subgenus 

 together with europs. 



The sexual characters are very slight. 



8. A. I II gens n. sp. — Form slender, sub-cylindrical. Pubescence short, 

 sub-erect, sparse, and inconspicuous ; surface of the body highly polished. 

 Head large and very robust, scarcely two-thirds wider than long ; interocular 



Stenini. 11
