THE CANADIAN ENTOMOLOGIST. MIT 



angulate ; colour yellow, with very broadly suffused M in livid-brown, 

 caused by the crowded punctures, the central forked mark being much 

 less sharply defined than in the preceding species ; elytra the same general 

 colour and shape as similis, but with the intervals behind the humerus less 

 broken, and the fourth interval is, on the contrary, broken up with punc- 

 tures. The elytral shield and livid markings are about the same in both 

 species (one of my £ 's has a specially-developed shield), marginal stria 

 lightly curved at lobe and barely sinuate behind, lobe well developed, 

 especially in $ , and with a well-marked series of punctures on the curve ; 

 below dark brown or livid, with yellow epimera and sides of abdomen, 

 legs pale, with darker clouds, pygidium as in similis. 



Five $'s, 7 9 's, Brownsville, Texas. Length, 2-2^ mm. 



The main points of difference from eburifer are approximate eyes 

 and shorter antenna? in £ , and elytral striae differently broken. 



Pachybrachys pusillus, nov. sp — -Small, or medium size, dull dirty- 

 yellow, elytra almost regularly punctate striate with a shield. Length, 



2-2^4 mr "i 



Head yellow, front convex, punctured, the usual dark lines very 

 faintly indicated in brown, eyes moderately distant in both sexes, antennae 

 yellow, the last five or six joints separately darkened at the ends, the tip 

 reaching the abdomen in the <$ ; thorax yellow, much wider than long, 

 constricted at front and rear, more, however, at the former, so that from 

 above the sides appear rounded, depression obvious, though not deep, 

 surface rather unevenly but thickly punctured, M faintly indicated in 

 livid, sides very feebly subangulate, especially in g ; elytra yellow, almost 

 regularly, very light brown, punctate striate, with an entire third interval, 

 which shows a well-developed shield ; the first short stria next the scutel 

 is irregular; there is also a break in the sixth and seventh intervals behind 

 the humerus : the curve of the marginal stria is very slight and almost 

 straight behind, the lobe is wide, with a well-marked row of punctures ; 

 body below yellow, with the middle livid, legs yellow, fossa wide and dull. 



6* and °. , Brownsville; 2 $ 's, San Antonio, Texas. Type coll., 

 Bowditch. 



The 2 (J's from San Antonio are smaller, but do not differ otherwise 

 from the Brownsville examples ; specimens from Chihuahua, Mexico, are 

 a trifle larger and more diffusely punctate around the scutel, and show 

 traces of the standard spots in livid, and approximate to nebulosus, Suff. 



Pachybrachys puncticollis, nov. sp. — Size small, pale yellowish-white, 

 with red-brown markings, very noticeable by the coarse and crowded
