THE GENUS PISSODES. 45 



Black Mountain, North Carolina, in 1905. The typo and one male 

 are in the type collection of the U. S, National Museum. Three 

 females and one male from the same locality, labeled, respectively, 

 "VI-17," "VI-17," ''VI-19," and "VI-30," were returned to the 

 American Museum of Natural History, New York City. A dead 

 specimen was collected by the writer at Camp Caribou, Maine, 

 June 7, 1900, on dead branch of "witch's broom," on balsam fir. 

 Larval mines and pupal cells were observed in adjoining twigs, and 

 another dead specimen was taken at Waterville, N. II., May 4, 1906, 

 from a pupal cell in dead branch of "witch's broom," on balsam 

 fir. Several specimens had emerged from the same branch. 



Distinctive characters. — This species is closely allied to P. utali- 

 ensis, from which it is distinguished by the moderately coarse pro- 

 notal punctures and the very large posterior spot which extends 

 anteriorly to the middle of the elytra, and is surrounded by a dis- 

 tinct dark border. 



Variations. — The specimens vary in length from 3.7 to 4 mm., 

 and in color from light brown to dark browTi, with but slight varia- 

 tion in the spots. Eight adult specimens were examined. 



Host trees. — Ahies halsamea; Abies fraseri. 



Distribution (Plate XIX, fig. 1). — (Hopk.U.S.) Maine: Camp Cari- 

 bou, Parmachene Lake. New Hampshire: Waterville. (A.M.N.H.) 

 North Carolina: Black Mountains. 



2. Pissodes utahensis ii. sp. 



The tjrpe specimen is labeled "Type No. 7425, U.S.N.M.;" name; 

 "type of drawing; Park City, Ut., 6.17; Coll. Hubbard & Schwarz; 

 952; S 1." 



Distinctive characters. — This species is closely allied to the pre- 

 ceding, from which it is distinguished by the coarser pronotal punc- 

 tures and the smaller posterior spots, which do not extend forward 

 to the middle of the elytra and do not have a distinct darker border. 



Variation. — There is very little variation in size, but the scales 

 vary from white to a yellowish brown. Five adult specimens, 4 

 males and 1 female, have been examined. 



Host tree. — Unknown, probably Abies. 



Distribution (Plate XIX, fig. 2).— (U.S.N.M.) British Columbia: 

 Bear Lake (Lontlon Hill ]\Iine). Utah: Alta, Park City.

 13, 1903]; H. S. Barber, collector; 327; 9 1." 



Distinctive characters. — This species is at once distinguished from 

 all of the other species of the first subdivision by its darker color, 

 the very coarse punctures of the pronotum and elytra 1 stria^, the
