THE CANADIAN ENTOMOLOGIST. 323 



Head yellow with heavy black frontal and vertex marks, sparsely and 

 finely punctate (except on the dark marks) ; eyes distant (antennae 

 wanting) ; thorax much wider than long, narrowed in front, medium 

 depression behind, black with pale frontal and side margins and median 

 line reaching a little beyond the middle and a suspicion of colour on the 

 rear margin ; the siirface shiny and very sparsely, finely punctate, espe- 

 cially on the disk, lateral edge just barely bowed ; elytra elongate parallel, 

 rather square behind, sparsely, finely and diffusely punctate, the punctures 

 coarse at the side, here and there arranged in rows, but only at the side is 

 there any suggestion of costate intervals and then short and poorly 

 defined, colour shining black ; with the forward inflexed edge to round the 

 shoulder, the tip, a few spots laterally behind the shoulder, at the con- 

 vexity and a few median sprinkles, yellow, marginal stria very lightly 

 curved, lobe rather long drawn out with a row of punctures; body below 

 black with the epimera and abdominal and pygidial spots yellow, legs 

 yellow, the tibiae and tarsi more or less fuscous. 



Two $ 's, Grand Lake, Colorado. 



Would be placed near signatifrons. Type coll., Bowditch. 



I note the occurrence of eburifer, Suff., from Brownsville, Texas, 

 also what is apparently rubronotatus, Jac, from Iowa and Illinois. Our 

 examples are smaller than the Mexican example cited in Biolog. Supp., p. 

 137 (which is in my collection), and with less yellow on the thorax and 

 more on the elytra, but the form and punctuation seem to me about the 

 same ; more specimens are needed from all localities. Mr. Blanchard has 

 also from Globe, Arizona, a specimen which I call var. of marmoratus, 

 Jac. It has the thoracic M very plain and the elytra pallid. Mr. Knaus 

 has two others much darker, one from El Paso, Texas, and the other from 

 Las Vegas, N. M.; the latter gentleman also has a specimen of vari- 

 color, Suff., from Cloudcroft, N. M., and baju/us, Suff, from Lower 

 California ; the latter species I have also seen from Texas ; also from 

 Cloudcroft, an example of hcematodes, Suff. In my former paper (Ent. 

 News) I refer to striatus, Lee, dark form as probably a new species. I 

 put it as nigricornis, Say.; characteristicus, Suff., which is typically dirty 

 white, occurs also almost entirely suffused with black ; Sonorensis, Jac, is 

 found in the Santa Rita mountains, Lundy and Truckee, California. It is 

 dull, rather flattened above, and comes near croftus, n. sp., brevicoltis, Lee, 

 and signatifrons, Mann. A series of specimens occur in Southern
