THE SPECIES OF ANABRUS AND 

 THEIR DISTRIBUTION. 



From an examination of ovei' two hundred 

 specimens of Anabriis from different parts of 

 the west, there appear to be four species in 

 the United States. The first described was 

 (i)^..s/')«//e;«Hald.(Stansb.Expl. Utah, 37;, 

 pi. 10, fig. 4) which was first recorded from 

 Salt Lake and is found over the interior pla- 

 teau west of the Rockj Mts., and north of 

 southern Utah to the Sierras and, bejond 

 them, in northern California, Oregon and 

 Washington. The figures of the species 

 given by Glover (Illustr., pi. 9, fig. i, pi. 14, 

 fig. 5), Thomas (Hajden's Fifth Ann. Rep., 

 pi. I, fig. i), and Packard (Second Rep. Ent. 

 Comm., 164) belong here, and this is prob- 

 ably the case also with the figures of Her- 

 man (Verb, zool.-bot. ges. Wien, J4 : pi. 6, 

 figs. 76-S6), which I formerly doubted (Rep. 

 Chief, eng., 1S76, 500). 



The second species described was (2) A. 

 pnrpiirascens Uhl. (Proc. Ent. soc. Phil., 2 : 

 550), a name which must be restricted to the 

 species found east of the Rocky Mts., from 

 Montana, Dakota and Manitoba over the 

 , prairies and plains as far as Kansas. The 



type specimens (in my collection) come 

 from Red River, Manitoba, and the speci- 

 mens mentioned by Uhler from Te.\as and 

 Washington probably belonged to other 

 species. A. similis Scudd. (H.ayd. Rep. 

 Nebr., 249) is a synonym of this. The fig- 

 ures given by Glover (Illustr., pi. 17, figs. 

 10, II J belong here, but that by Packard 

 (Second Rep. Ent. Comm., 163) belongs to 

 the next species. 



This is (3) A. coloyadus Thorn. (Hayden's 

 Fifth Ann. Rep., 440;, redescribed in part by 

 me (Rep. Chief Eng., 1S76, 500), a mountain 

 and alpine form, found mostly in Colorado 

 but also extending south to New Mexico and 

 Texas, unless the specimens from the latter 

 state (of which I have but few, in poor con- 

 dition) belong to A. purpnrnsceiis. As stated 

 above, this species is figured by Packard 

 under the name A. furpiirascens. 



A (4) fourth undescribed species in my 

 collection, from Texas, is readily distin- 

 guished from the others by its much slenderer 

 and relatively longer legs. The other species 

 referred at different times to Anabrus do not 

 belong here (See Can. Ent., 26: iSo-8i.
