THE CANADIAN ENTOMOLOGIST. 



Larger (2.5 mm.) ; middle tibiae of £ more slender and strongly 



thickened near base Lecontei, Brend. 



, Antennae with second joint cylindrical, not appreciably narrow at 

 tip ; middle tibiae of ^ with a strong tooth about one-third from 



the tip Taylori, n. sp. 



Figures of the antennae and middle legs of the males of three of the 



above are given, the sketches having 

 been made with the aid of a camera 

 lucida. Care has been taken to get 

 a like point of view in each case. 

 The spine of the middle leg has 

 been figured as part of the .tro- 

 chanter in A. Lecontei by Dr. 

 Brendel*, who was misled, I sup- 

 pose, by the use of imperfect lenses. 

 In specimens of an Adranes from 

 Iowa City, determined by him as 

 his Lecontei, the spine is femoral 

 in origin, as shown in my figure 

 (Fig. ia). to which I have added a sketch of the antennae (Fig. ib) 

 for comparison with the others. 



The new forms may be described thus : — 



Adranes pacificus, n. sp. — Reddish yellow, less shining than A. 

 Lecontei or A. Taylori. Above finely punctured, pubescence yellowish, 

 recumbent, coarser than in either of the previously mentioned species and 

 more inclined to form regular lines. Head (in profile from above) 

 broadest just behind the antennas, thence almost regularly narrowed to 

 base, sides hardly arcuate, frontal margin truncate. Second antennal 

 joint straight, distinctly narrowed to the tip and somewhat thicker in 

 proportion to the length than in A. Lecontei. Pronotum resembling that 

 of A. Taylori, but the lateral impressions are less deep, and in con- 

 sequence the sides in front of them appear less bulging ; basal fovea 

 naked, deep and almost exactly circular. Elytra at base about equal to 

 the base of the prothorax or very slightly wider, conjointly deeply 



* Bulletin from the Laboratories of Natural History of the State University of 

 Iowa, Vol. I., pi. VI., Fig. 3. The same origin is ascribed to this spine in A. cacus, 

 1. c. pi. VI., Fig. 5 ; and p. 221. However, I have not seen the latter species, and 

 make no further comment.
