Lesser oak carpenter worm 



Prioiioxystns DiacDiurtrci Guer-Mcn. 



A brown-headed, greenish hirva, with rose-colored elevated points, about ij!^ inches 

 long, bores in black oak. 



This species is closely allied to the carpenter -worm, P. robin iae 

 Peck, noticed on page 79 and has very similar habits. It appears to be 

 much rarer than its larger relative, though we have met with pupal cases in 

 the Adirondacks which seemed referable to this species. 



Description. I)r Fitch describes the moth as slightly smaller than 



P. robin iae, with thin, slight, transparent wings crossed by numerous 



black lines, the outer margin only of the fore pair being opaque and of a 



gray color. The hind wings of the male are colorless with the inner margin 



broadly blackish and the hind edge coal-black. 



The larva has been characterized by Dr Lintner as an inch and a half 

 long, pale green with a darker green dorsal stripe bordered faintly with 

 yellow. Head flat, subtriangular, dark brown clouded with black. F"irst 

 segment with two brown spots extending across it, narrowed laterally, and 

 of nearly the length of the segment medially where they unite to enclose 

 on the dorsal line an elongate elliptical green spot. The anterior segments 

 are flattened, and broader than the following, which gradually diminish in 

 breadth toward the posterior end. The segments are marked dorsally with 

 four rose-colored elevated points forming a square on the loth and iith 

 segments. A similar spot occurs above each spiracle, a smaller one below 

 and another in front, each tipped with a short brown hair. The spiracles 

 are oval, orange colored with brown centers. 



Lepturges querci Fitch 



A small, black, yellowish gray marked, long-horned beetle may be reared from dead 

 limbs of hickory, oak and other trees. 



Two Specimens of this interesting little species were reared from dead 

 branches of hickory limbs taken at Ilion N. Y., May 17, 1902, the insects 

 issuing June 10 and 11. This tree was badly infested by a knotty, gnarly 

 growth, and presumably was in far from a thriving condition. 



Description. This little longicorn is about 3/16 inch in length, black, 

 with irregular markings of yellowish gray on the wing covers. Seen from
