also than usual, and with a slight eraargiaation. Elytra obliquely subtruncate 

 at tip. 

 Female. — Antennae feebly subserrate. Elytra rounded at tip. 



The speciiueus collected by Crotch had yellow elytra. I have two 

 from New Mexico, entirely piceous above. This species is kaown by 

 the narrower thorax, vaguely impressed above. 



Occurs in California, (Temescul), and New Mexico. 



The last named species bears the same relation to the others that 

 the species of Magdalis do among themselves, those Mi/cterus with the 

 thorax broadest at base resembling Magd. Lecontei, while quadricoUis 

 represents Magd.. harhita. Closely allied to Mycterua but dilFering by 

 several important characters is 



liACCONOTUS Lee. 



Here the head is not elongated and the palpi shorter although of 

 similar structure. The elytral epipleurae do not reach the tip. First 

 segment of abdomen shorter than the second. Tibiae without termi- 

 nal spurs. 



Two species are known. 



Black, thorax reddish-yellow with median black space pnnctalus Lee. 



Piceous, elytra less coarsely punctured than the thorax pinicola n. sp. 



li. punctatus Lee, Class. Col. N. A. p. 255. — Moderately elongate, black, 

 sparsely pubescent, thorax red with discal black space. Head densely punc- 

 tured, black. Thorax quadrate, sides feebly arcuate in front, surface coarsely 

 punctured, disc slightly impressed each side of middle. Elytra coarsely and 

 densely punctured. Body beneath (and legs) black, sparsely punctate. Length 

 .17— .22 inch J 4.25—5.5 mm. 



Male. — -Second abdominal segment notably longer than the third and at 

 middle more convex, smooth and testaceous, recalling the tubercle of Myc. 

 canescens but larger. 



It is interesting to find a similarity of sexual characters between 

 this and three of the Mycterus, although the tubercle is on the second 

 instead of the first segment. 



Canada, Michigan, Pennsylvania, very rare. 



li. pinicola n. sp. — Piceous or black, elongate, moderately shining, sparsely 

 pubescent. Head densely punctured, antennee and mouth rufous. Thorax 

 quadrate, sides feebly arcuate in front, disc densely punctured and with a very 

 vague oblique impression each side. Elytra broader than the thorax, nearly 

 five times as long, slightly broader behind the middle, moderately densely and 

 more finely punctured than the thorax. Body beneath moderately densely 

 and finely punctured. Length .22 — .26 inch ; 5.5 — 6.5 mm. 



Male. — Second ventral segment with a small oval elevated space covered 

 with short brownish pubescence. 



This species differs from the preceding in the form of the antennae, 

 here they are a little longer than the head and thorax, the joints 

 rather slender and longer than wide. In punctatus the antennas
