on the coast of the Island of Chtagaluk, under sea drift. When Dr. 

 Leconte reviewed the genus (Tr. Am. Ent. Soc, VIII., 177,) there was 

 before him a small male example from Unalaschka. also a male from the 

 coast of Mendocino, Northern California ; and on the latter a species was 

 erected, the two forms being separated thus : — 



" Head not wider than the prothorax, which is feebly narrowed behind, 

 and not sinuate on the sides ; basal angles obtuse, rounded, length 2.7 

 mm. [that of type 2 lin=, 1775 tnc/i.] — drevi^enuis." 



" Head wider than the prothorax, which is strongly narrowed behind, 

 with the sides subsinuate near the base ; basal angles rectangular, very 

 slightly rounded ; 3.6 mm. — cordicoUis." 



There are before me 3 $ and 2 $ examples of brevipemiis ; one of 

 the males has the head scarcely as wide as the thorax, another subequal to 

 and a third greatly wider ; in this example the thorax is narrowed to two- 

 thirds at base, with the angles somewhat rectangular ; in the others as 

 well as in the females it is more or less narrowed, with the basal angles 

 varying from obtuse to strongly rounded. The females have the head 

 and thorax subequal and the last ventral segment rounded. In both 

 sexes the dorsum of the thorax is widely arcuate, and more or less 

 deeply concave from the base to the middle. The characters relied upon 

 by Dr. Leconte to establish his species seem to be inherent also in 

 Mseklin's. These examples are from the Queen Charlotte Islands, the 

 fauna of which, judging from the portion of it seen, or lately recorded, 

 appears to be identical with that of the neighboring Alaskan Islands. 



Deiidrophagus glaber, Lee. — An example of this wide spread northern 

 species occurred here in April of this year, and I saw another taken near 

 the same time in Elk County, Pa. 



Brontes dubiiis^ Fab., truncatus, Mots., and debilis, Lee. — Mr. T. L. 

 Casey (Tr. Am. Ent. Soc, XL, 99) says oi debilis : "This is the common 

 northern species, while dub ins is more plentiful at the South." This 

 remark, which is probably a clerical error, is occasioning trouble among 

 a certain class of collectors who have Mr. Casey's paper. The fact seems 

 to be the reverse. While dubius is excessively abundant here and north- 

 ward, debilis has not occurred, neither is it on any of the northern cata- 

 logues, with one exception, which examples from its author show to be 

 an error. I cite Leconte in Agaz. Lake Sup., No, 61 (Hamilton and 

 Henshaw's Cat.); Harrington, No. 34; Brodie and White, No. 12;
