populated mostly by hilituratus while the margins of those clearings 

 support hruneri. Hebard (1930) remarked on the very different 

 habitat preferences of hruneri and hilituratus (mexicanus), and this 

 distinction was also brought out by Handford (1946, p. 172). The 

 "rather hot and dry valley fields" where Fulton (1930) found hruneri 

 in Oregon probably were adjacent to sylvan conditions. Specimens 

 of hruneri (10 cf , 9 9) in the Philadelphia collections, from Red Banks 

 in Logan Canyon, Utah, apparently are those referred to by Hebard 

 (1936b, p. 173) as M. utahensis, said to be abundant in areas of 

 "cow cabbage" (Wyethia amplexicaulis Nutt.) 



Nymphs of hruneri have been illustrated by Handford (1946), who 

 found that they resembled darker nymphs, at least, of hilituratus 

 hilituratus (=mexicanus) in every respect. 



In northern Michigan adults of hruneri are not abundant until the 

 beginning of August (Hebard, 1909). It has been suggested (Canad. 

 Insect Pest Rev., vol. 33, p. 10, 1955) that since the 1954 outbreak 

 in parts of British Columbia seemed related to one in 1952, while the 

 1953 infestation was light, the life cycle there may occupy two years. 

 Collection dates on the great majority of specimens examined are in 

 August and late July. Some of the more limital dates are as follows : 

 Francis Lake, British Columbia, July 5; Castleton, Utah, July 5; 

 ChUcotin, British Columbia, Aug .1; 37 miles southeast of Fairbanks, 

 Alaska, Sept. 1; Drain, Oreg., Sept. 11; Therma, N. Mex., Sept. 12; 

 GaUatin Canyon, Mont., Oct. 3. 



Some of the altitudes (in feet) on labels of specimens examined are 

 as follows: Evergreen, Idaho, 3,600; Strawberry Mts., Oreg., 4,450; 

 McCall, Idaho, 5,000-5,050; Jackson Hole, Wyo., 6,500; Fishers Peak, 

 Colo., 7,000-8,000; Cascade Canyon, Teton National Park, Wyo., 

 9,000; southwest base of Delano Peak, Utah, 10,000; Mt. Wheeler, 

 Nev., 10,000-10,600; Mt. Lincoln, Colo., 11,000-13,000.

Caloptenus spretus Walsh, Pract. Ent., vol. 2, p. 1, 1866 (Highland, Kansas). 



Neotype here designated: Male labeled "Lawrence, Kans. June 18, 1877, 



Geo. F. Gaumer" (USNM). 

 Caloptenus spretus caeruleipes Cockerell, Entomologist, vol. 22, p. 127, 1889 



(probably Glencoe, Nebr., where observations by Dodge (1878) presumably 



were made). 



The condition of the neotype is excellent, with colors well preserved 

 and all appendages present. The aedeagus and epiphaUus have been 

 exposed as dry preparations still attached to the body (see figs. 

 3,a-2,3; 10,a). The subgenital plate and cercus are shown in figures 

 16,a-2 and 7,6-1. Measurements (in millimeters) are as follows:
