Baring 355 



thorax, the latter three-fifths wider than long, the sides parallel and 

 rather arcuate, rounding and transversely converging in about apical 

 third, the apex subtubulate and only two-fifths as wide as the base; 

 punctures coarse, deep, dense laterally, smaller and sparse medially, 

 wanting in a moderate medio-basal area; base bisinuate, the lobe large, 

 rounded; scutellum ogival, flat, nearly as long as wide; elytra two-fifths 

 longer than wide, not quite as wide as the prothorax, except at the 

 prominent rounded humeri, and two-thirds longer, ovoidal in outline; 

 surface as in utidulatus, except that the lateral punctures are rather 

 coarse and much more conspicuous, and the striae coarser and distinctly 

 punctured though not crenulate; pygidium finely, deeply and closely 

 punctate; under surface opaque, sculptured nearly as in tmdiilatus, the 

 femora strongly, densely and rugosely punctate, the anterior with a 

 small triangular tooth beneath. Length (cf) 4.0 mm.; width 1.8 mm. 

 Florida (Lake Worth). One example. 



Dififers conspicuously from undulatus in sculpture, the coarse 

 lateral punctures of the pronotum and fianks of the elytra being 

 amply distinctive. 



The following two Texan species are allied to the subtropical 

 cimeatus and allies: 



Madarellus perditus n. sp. — Oblong-cuneiform, strongly, convex and 

 polished throughout, red-brown to black, almost sculptureless above; 

 beak arcuate, rather closely punctulate, as long as the prothorax (cf ) 

 or head and prothorax (9 ), the latter two-fifths wider than long, inflated, 

 the sides broadly arcuate, becoming parallel posteriorly, more rounded 

 and converging anteriorly to the subtubulate apex, which is three- 

 sevenths as wide as the base, the latter transverse and with an abrupt 

 rounded median lobe; punctures extremely minute and sparse, the sides 

 and inferior surface feebly, obliquely rugulose as usual; series of fine 

 punctures along the base evident; scutellum small, flat, ogival, slightly 

 transverse; elytra acutely ovoidal, scarcely two-fifths longer than wide, 

 not quite as wide as the prothorax and nearly three-fifths longer, the 

 humeral callus rather large, prominently rounded; surface undulated; 

 stria; smooth, deep but fine; interstitial punctures scarcely traceable at 

 any part; under surface feebly, the abdomen strongly, shining, the latter 

 sparsely punctate; femora rugosely and densely punctate, the anterior 

 acutely denticulate beneath. Length Ccf 9) 2.5-3.0 mm.; width 1.15- 

 1.5 mm. Texas (Brownsville), — Wickham. Four specimens. 



This species is allied rather closely to cuneatus Csy., the type of 

 which was taken by Wickham at San Antonio; it differs, however, 

 in its less abbreviated and less rapidly cuneiform outline and longer 

 elytra; in cuneatus the elytra are barely a fifth longer than wide 

 and less than one-half longer than the prothorax. 



Madarellus imulus n. sp. — Oblong-suboval, strongly convex, polished, 

 piceous-brown; beak in the female arcuate, distinctly longer than the
