abundant; head broad; clypeus not much produced, the lower half 

 black; supraclypeal area brassy; front and sides of face well punc- 

 tured, the middle of front as closely punctured as possible, not 

 striate; antennae black; chs.ks shining; mesothorax shining, strongly 

 and rather closely punctured all over; scutellum closely, more 

 finely punctured; area of metathorax strongly sculptured all over 

 with anastomosing ridges, producing a finely reticulate effect; 

 tegukr rufofuscous with paler margins, impunctate; wings hyaline, 

 not reddish; stigma and nervures reddish testaceous; hind spur

South Island, Coronado Islands, L. Calif., Aug. 21 (7\ and W. 

 Ckll.). Fi\'e females, visiting Compositae. One would not take 

 this for a southern or desert species; it rather has the aspect of 

 those of the mountains and of the north. It falls near to H. 

 perpimctatus Ellis, but has the mesothorax more coarsely and less 

 densely punctured, wings not reddish, area of metathorax shorter, 

 etc. A related but quite distinct form, which Mrs. M. D. Ellis 

 has named in manuscript as a subspecies of H. perpunctatiis, occurs 

 in Southern California. I have named this species and the next 

 after the naturalists to whom we are indebted for an excellent 

 account of the birds of the Coronado Islands.
