R.UTELIN/E 83 



similarly ogival but very nearly as long as wide; thoracic angles well 

 denned, not rounded. Body less expanded, the elytra broadly 

 rounded and not so explanate before the middle; head not so large, 

 a little more than half as wide as the prothorax, the punctures 

 similarly disposed but more distinctly denned, the clypeus nearly 

 similar but not so broad; prothorax about twice as wide as long, the 

 sides similarly broadly subequally arcuate and nearly parallel, the 

 apical angles prominent, with their apices well denned, the basal 

 more than right but not more than blunt at tip, the ambient bead 

 similar but not quite so thick; punctures similarly fine and sparse 

 but better defined and stronger and closer antero-laterad; scutellum 

 punctured nearly throughout; elytra a fourth longer than wide, at 

 or before the middle more than two-fifths wider than the prothorax, 

 almost similarly but more finely sculptured; pygidium not so strongly 

 sculptured, the punctureless median line not tumid, the marginal 

 impression similar; epipleura not so wide but similarly rugosely 

 sculptured; intermesocoxal tumidity small and rather acute an- 

 teriorly; hind coxae shorter and more transverse than in ampliata. 

 Male differing considerably from the foregoing female, being smaller, 

 with relatively more elongate, more parallel and more evenly though 

 feebly arcuate sides, the pygidium less strongly sculptured, less 

 transverse and with the impressions near the lower margin obso- 

 lescent; sixth ventral with a very shallow apical sinus, the coriaceous 

 seventh segment black, the sexual characters exactly as in Pelidnota. 

 Length (cf) 25.8, (9) 29.5-30.0 mm.; width (cf) 14.0, (9) 16.0- 

 16.8 mm. Arizona. Huachuca Mts. at Garces and an unrecorded 

 place, the latter female differing somewhat from the first in having 

 the eyes relatively a little smaller and less prominent, .beyeri Skin. 

 A Male somewhat as in the male of beyeri but with larger and much 

 more prominent eyes and without a distinctly defined median 

 lobe at the base of the prothorax, the anterior angles of the latter 

 more rounded, the punctures similar but less sparse throughout; 

 elytra more oval and less elongate, about a fourth longer than 

 wide a third longer than wide in beyeri the sides more rounded, 

 the sculpture similar in general type, the punctures, however, 

 more minute and still sparser; pygidium much more impressed 

 along the oblique sides beneath, about as much as in the female of 

 beyeri; antennae more pallid, very pale red-brown, the basal joint 

 only feebly metallic. Length (cf) 26.7 mm.; width 13.5 mm.

 collection ocularis n. subsp. 



I am inclined to think that, with both sexes at hand, ocularis 

 could be shown to be specifically different from beyeri, but would 

 suggest the above relationship provisionally. There are evidently 

 a number of distinct species and subspecies of the woodi and beyeri 

 type in southern Arizona and the neighboring parts of Mexico. 

 The following subspecies seems worthy of definition at this time;
