172 THE CANADIAN ENTOMOLOGIST. 



Adoxus, Kirby. 

 Represented by A. obscurtis, Linn., var. vitis, Fabr., a broad- 

 shouldered insect about .20 to .25 in. long; the thorax dark brownish 

 or black and much narrower than the yellowish elytra, which are punctate 

 in rows and clothed with a fine whitish pubescence. Legs dark, tibiae 

 paler. The typical obsciinis has the elytra dark, unicolorous with the 



thorax. 



Glyptoscpxis, Lee. 



The only record is of G. pubescens, Fabr., a rather large (about .35 

 in.) insect of somewhat parallel form and green-bronze colour, clothed 

 with a pubescence <?f mixed cinereous and yellowish hairs. The thorax 

 and elytra are confusedly and distinctly punctured ; the neighbourhood of 

 the scutellum has a depressed space. Legs more or less reddish. 



Typophorus, Er. 



T. canellus, Fabr., is one of the most variable of our Chrysomelidte. 

 It is a small insect, not exceeding .t6 in. in length; the thorax narrower 

 than the elytra, which are distinctly punctured in rows. Surface shining. 

 In colour there is such a variation as to have given rise to several varietal 

 names, aterriina, Oliv., having been applied to an entirely black form. 

 The name 4-notatus, Say, belongs to a variety with black thorax and 

 spotted elytra, while 4'guttattis, Lee, has a yellow or reddish thorax and 

 spotted elytra. Others occur, but not having been recorded from the 

 region under consideration, they are passed by for the present. A full 

 account of them will be found in Dr. Horn's paper. 



Chrysochus, Redt. 



A common species on the Dog's-bane (a milk-weed) is C. auratus, 

 Fabr., a large green-bronze beetle, about .40 in. long, often with the most 

 brilliant golden reflections. The body is rather more elongate in form 

 than the preceding species and very convex. There is also a record of 

 C. cobalt'mus, Lee. (properly a Pacific Coast species), which is of blue 

 colour, sometimes with a touch of green. 



Tymnes, Chap. 



L. tricolor^ Fabr., is a rather brilliant beetle, about .25 in. long, 

 metallic green or bronzed in colour, the legs almost always reddish or 

 yellowish, the upper lip pale. Elytra coarsely punctured, acute at apex ; 

 "anal segment often pale, especially in the males, in which sex that seg- 

 ment is broadly emarginate and with a transverse depression" (Horn).
