 ular transverse, subconcentric rows of granules, sides and base sparsely 

 but distinctly punctured. Elytra with striae composed of small punctures; 

 intervals wider than striae, alternate ones with four or five distinct punc- 

 tures of equal size with those of the striae; sutural stria slightly impressed.

 tinct traces of teeth and no range of spines or fringe of stiff hairs as in 

 P. obliquus. Length 1:5 mm. 



Tampa, Fla., April, one specimen. Occurs on pine. {Rchicarz.} 



1014 (9069). PITVOPHTHORUS PULCiiKLLrs Eich., 1868, 275. 



Subelongate. Black, shining, almost glabrous. Thorax shortly ovate, 

 dilated toward base, in front almost equally rounded, narrowed, strongly 

 rugosely punctate behind, asperate with tubercles in front. Elytra cylin- 

 drical, narrower than thorax, striato-punctate; intervals distantly unise-

Described from North America; the first of the c/cuits to be 

 ilrxt-rihrd. Known from Michigan, Pennsylvania, District of Col- 

 umbia and West Virginia. Food plants, Finns and Picea. Eich- 

 hoff (189G) states that P. Jiirtircps Lee. (1878, (;2.,|, described 

 from Marqnette, Lake Superior, "is extremely close to, perhaps 

 identical with P. I'mlchelliis," and we have included its recorded 

 distribution with that of the latter species.
