134 WILLIAM G. DIKTZ, M.D. 



S. tesselatus n. sp. — Ovate, robust, strongly convex, black ; legs and an- 

 tennae rufopiceoiis, iindersicie densely covered with large, oval, whitish or yel- 

 lowish white scales, those of the upper surface smaller, brownish, conspicuously 

 mottled with spots and lines, consisting of large white scales. Beak very feebly 

 curved, densely punctured and scaly from base to beyond the middle, indistinctly 

 subcarinate and striate, a little longer than head and prothorax in the male, 

 much h)nger and somewhat shining toward the apex in the female, basal tufts and 

 constriction feeble. Antennje not very slender, first joint of funicle rather robust, 

 second very little longer than the third, outer joints moderately wider, club densely 

 pubescent. Head feebly shining, alutaceous, front coarsely punctured, scaly. 

 Prothorax distinctly wider than long, narrowed anteriorly, sides strongly and 

 somewhat suddenly rounded in front, convergent and nearly straight behind the 

 middle, apex broadly constricted, densely and lather coarsely, but not deeply 

 punctured : a median entire vitta, an interrupted one each side of the disc, and 

 a line on the lateral margin, consisting of white scales; scutel extremely small, 

 almost invisible. Elytra oval, two-fifths wider at base than the prothorax, 

 widest at the middle, sides rounded, humeri rounded, prominent; strife not deep, 

 rather wide, coarsely and remotely punctured, interstitial setae fine, distinct; 

 humeral, basal line on the third interspace and spots and lines on the disc of 

 large white scales, the scales of the sutural interspace are of a paler brown 

 than those of the disc. Prosternum broadly, but not deeply sulcate, antecoxal 

 ridges prominent in front; postocular lobes not very prominent. Thighs rather 

 slender; tibise moderately robust and rather short, widened to the tip, ante- 

 rior and middle setulose within ; terminal hooks, except on the hind pair, 

 quite distinct; tarsi stout, fourth joint scarcely longer than the third, projecting 

 about one-half the length of the latter; claws small, connate scarcely one-half 

 their length, divergent. Length 2.2.5— 2.5 mm. , 0.09— 0.10 inch. 



Hah. — Texas, District of Columbia. 



Scarcely to be distinguished from squaUdiis, from which it differs 

 by the less elongate first joint of the funicle, the second joint but 

 little longer than the third, the claws connate scarcely one-half their 

 length, and by its smaller size. Confounded in collections with 

 ovipennis Lee. 



S. 4»vil>eiinis Lee. — Subovate, convex, pitchy black, autennjeand legs rufo- 

 piceous ; rather densel.v clothed with ashy gray scales, smaller on the underside, 

 larger and broadly oval above, without mottliugs. Beak robust, longer than 

 head and prothorax, tricarinatc, median carina finely canaliculate, intervening 

 sulci coarsely punctured, squamose from base to about the middle, basal tufts 

 not well marked, constriction rather deep. Antennae, with the second joint of 

 funicle distinctly longer than the third and but little shorter than the first, which 

 is moderately stout. Head as in tesselatus. Prothorax wider than long, narrowed 

 in front, one-fourth wider at base than at the apex, the latter broadly, but not 

 strongl.v cou.stricted ; sides broadl.v and not ver.y strongl.v rounded; surface 

 densely punctured, punctures rather coarse and close set, more or less concealed 

 by the scales; scutel glabrous, distinct. Elytra subovate, about one-third wider 

 at base than the prothorax; humeri rather prominent, sides broadly rounded 

 from base to apex, strise rather coarse, deep; punctures large, remote, interstitial
