pitch in Jaiiuarv, it may be that the species winters in the larval 

 state, and that it is single brooded. The identification of these 

 winter larvse is not complete. In color they are more pinkish than 

 the specimens taken in June. Again, whether the larvse feed on the 

 gum or not is uncertain, though certain of the facts observed point 

 to this conclusion." The insect is found in New York and Pennsyl- 

 vania, and Mr. Grote says he has known it to be in such abundance 

 that young Pine trees were killed by it. 



Mr. Zimmermann (Can. Ento. x, 20, 1878), says: "There is 

 scarcely a Pine more than four feet high on our grounds that is not 

 more or less affected by this borer." Further on he says: " Pinus 

 aylvestris seems to suffer most, as the limbs, and often the main stem, 

 are constantly breaking off." 



Mr. Kellicott says (Can. Ent. xi, 115): "April 12th I took many 

 larva of various sizes, .25 — .70 of an inch (6-18 mm.) in length 

 when crawling, so there is no longer any doubt as to the winter 

 stage. None of those taken were ' livid, or blackish green,' but dull 

 white ; nor do the hairs arise from a ' series of black dots,' but from 

 light brown ones. I take it to be a case where a naked hibernating 

 larva is lighter than during the warm summer." 



4. P. albovittella n. sp. — Expands 25 mm. Labial palpi and liead fus- 

 cous gray; thorax gray; abdomen light gray ; antennse fuscous, tuft black; fore 

 wings light gray, overlaid more or less thickly with a powdering of black ; basal 

 field rather long ; at the middle a raised ridge of black scales: basal line white, 

 bidentate, lined with black on the outside; discal spot white, rather large, oval, 

 consisting of large raised scales; outer line bidentate, wavy, lined with black 

 within, extreme costa blackish ; a faint shade of reddish basally. Hind wings 

 transparent light fuscous, darker on veins. 



Hot Springs, N. Mex., August. This insect has considerably the 

 appearance of the lighter specimens of Salebria contatella Grote.
