broadly, deeply arcuately emarginate at apex in the male, and 

 acutely rounded in the female. Prosternum feebly convex, the sur- 

 face sparsely and coarsely punctate, becoming coarsely rugose at the 

 sides, spareely clothed with long inconspicuous hairs; anterior mar- 

 gin nearly truncate in front; prosternal process nearly fiat, the sur- 

 face smooth, with a double row of irregularly placed coarse punc- 

 tures, from which arises a series of rather long hairs, and which are 

 more distinct in the male than in the female, the sides expanded 

 behind the anterior coxal cavities, then arcuately emarginate and 

 narrow u'd to the apex, which is rather narrowly rounded. 



Lo^ gth, 20-29 mm. ; width, 6.5-10 mm. 



Tais species was originally described by Drurj^ from Virginia, 

 it is a very common insect and the larvae infest various species 

 of pines. It is distributed over the entire eastern part of the United 

 States, and extends southward into Mexico and Central America. 

 I have not seen any specimens from the West Indies, so the above 

 description was made from a specimen collected in Virginia. 

 Chevrolat (1867) records a single specimen having been collected 

 in Cuba, which was probably imported from the United States. 

 Gundlach (1891) states that it is not indigenous to Cuba, but has 

 been intioduced in ships from North America.

Head more or less depressed, distinctly wider in front than on 

 vertex; front not narrowed by the insertion of the antennae, and 

 sometimes feebly longitudinally grooved; epistoma emarginate in 

 front; antennal cavities small, rounded, and situated under an ele- 

 vated carina at a considerable distance from the inner margin of 

 the eyes. Antennae short; first joint elongate and feebly clavate at 

 apex; second short, obconic; third elongate, nearly as long as first 

 joint, and feebly triangular; fourth nearly as long as third, but 

 broader at apex; following joints triangular, slightly longer than 

 wide, dentate on the inner side, except the last joint, which is oblong; 

 the last eight joints armed with poriferous pores, and more or less 

 distinct foveae on both sides of the joints. Eyes large, strongly 

 convex, broadly oblong, and distinctly closer to each other on the
