658 Coleopterological Notices, IV. 



evenly arcuate, as long as the head and prothorax, the antennae inserted be- 

 hind the middle, the club very large, more robust than usual, as long as the 

 entire funicle excepting one-half of the basal joint, the latter as long as the 

 next three, second not longer than the third. Prothorax less transverse than 

 usual, one-half wider than long, the sides feebly convergent and slightly 

 arcuate to apical third, then rounded to the tubulate apex, which is one-half 

 as wide as the base, the latter transverse, arcuate at the sides, the median 

 lobe distinct ; disk with a small, ill-defined elongate impunctate spot behind 

 the middle, the punctures coarse, deep, rounded, dense. Scutellum quadrate, 

 small, strongly impressed. Elytra somewhat abruptly nearly one-fourth wider 

 than the prothorax, more than twice as long as the latter and distinctly longer 

 than wide, the humeri moderately prominent, smaller and more basal than 

 usual ; sides behind them only moderately convergent, the apex rather broadly 

 and abruptly rounded ; disk with coarse deep very abrupt and non-crenulate 

 grooves, the intervals flat, subequal, but slightly wider than the grooves, each 

 with a single series of coarse deep confluent punctures. Length 2.8-3.1 mm. ; 

 width 1.4-1.65 mm. 



Arizona. 

 , In one of the specimens before me the pronotal punctures are 

 very dense, almost in mutual contact, but in the other are separated 

 by one-half of their own diameters, displaying, as in many other 

 species, marked variation in the coarseness and density of sculpture. 



ZAGLYPTUS. 



LeConte— Proc. Am. Phil. Soc, XV, p. 236. 



In this remarkably distinct genus, the body is minute and sparsely 

 covered with long stiff erect bristles, the beak moderate in length, 

 evenly, feebly arcuate, with the antennae inserted just bej^ond the 

 middle, the prosternum broadly, rather feebly impressed along the 

 middle, separating the coxa3 by much less than their own width, 

 and the tarsi very slender, the third joint elongate, subcylindrical 

 or feebly obconical and not in the least dilated. Zaglyptus was in- 

 advertently placed in the Cryptorhynchini by its author. 



We have but two species, one of which I do not have before me 

 at present; they are distinguished by LeConte as follows: — 



Elytra with coarsely punctured shallow striae, the intervals rather wide. 



1 striatus 



Elytra deeply sulcate, the grooves punctured ; interspaces narrow ; color 



darker 2 sill cat us 



These species appear to be rare, or at least seldom taken; they 

 are probably of peculiar habits.
