near Williams, Ariz., but never found it in the valleys. Eleodes 

 cordata is a common Northern species, and E. pimelioides extends 

 as far East as Green River, Wyo. E. opaca has the same range 

 (as far as my experience goes) as E. planipennis, and seems to be a 

 montane species. E. fnsiformis, a curiously-shaped species, oc- 

 curred only at Coolidge and Albuquerque, and is rare. 



The next genus, Embaphion, is remarkable for having the sides 

 ot the thorax and elytra more or less explanate and reflexed, as in 

 Scaphinotus, among the Carabid?e. Of the species I have seen 

 this character is most strongly marked \r^E. muricatiim, which oc- 

 curs in Nebraska, Dakota, Montana and Colorado, from May to 

 August. It seems to be rare, at least I got only about half a dozen 

 specimens on my last trip. E. depression and elongatum are found 

 at various points in New Mexico and Arizona from April to Sep- 

 tember. They are provided with a secretion something like that of 

 Eleodes. but which leaves a reddish stain on the hand when soap and 

 water is applied, instead of a yellow or brown stain as in the latter 

 genus. Trogloderus costatus is a remarkable insect which I have 

 taken in the vicinity of cottonwoods at Winslow, Ariz., and Green 

 Ri\er, Wyoming. 



Eidabis pubeseens may be found along the sea-shore at San 

 Diego under logs and boards in company with Amphidora nigropi- 

 hsa, and an occasional Cratidus osculans. The last species also 

 occurs at Los Angeles, so it is not confined to the immediate neigh- 

 borhood of the coast. 



One specimen of Argoporis costipennis was taken near Peach 

 Springs, Ariz., under an old cowhide in August. I never met with 

 another example. 



Iphthimus serratus is a well-known Northern species, and infests 

 the pine, li\'ing beneath the bark of dead trees. In Arizona it is 

 represented by the variety siiblcevis, which has the same habits. My 

 specimens are from the vicinity of Williams at an altitude of about 

 7000 feet. It does not occur in the plains where the pine trees are 

 lacking. Ccelocnemis punctata (a nearly smooth variety) is found 

 with it, while at Winslow and east into New Mexico a rougher form 

 extends. Upis ceraniboides I took under the bark of cottonwood 

 at Glendin, Mont., with a few specimens of Nyctobates pennsylvanica. 

 At the Needles I took a new Alcephus under a board. Mecysmus 

 angustatus flew to my light at Winslow, Ariz. The species ot 

 Blapsiiniis have habits so similar to one another that the description 

 of one will do for all. They are found under pieces of wood or dry 

 dung, among dead leaves or beneath rubbish of any sort, and some
