hairs. Head punctured ; uosl- rctiexed, emargiiiate ; stalk of the antennae 

 testaceous, scape and knob ])lnck ; palpi dusky : prothorax punctured, less 

 hairy in the disk, not channelled : elytra black, very short, depressed next 

 the suture with an intcnncdiate ridge; at the l)ase is a large i)ale-yellow 

 spot common to both elytra, from which run a pair of narrow, white, 

 mealy bands, which nearly rcaih the external margin, and a white mealy 

 stripe adjoining the suture also runs from the same spot to the apex of the 

 clytrum : the iiodcx is cosered with hmg yellowish hairs, so thick on the 

 sides as almost to corneal the ()b!ong white mealy spot common to the 

 subgenus : legs black. 



N. H. In the specimen taken in the Kxjjedition. the white mealy 

 stripe next the suture appears to have been rul)bed off and and is replaced 

 by a continuation of the pale spot. | Previousiv described as 1\ atjiyiis

IJody obovate, black ; covered, i»articularly underneath, with longish 

 pale hairs. Head \ cry thickly ])unctured ; no.se rellexed, emarginate ; 

 stalk of the antennae, excluding the scape, testaceous : prothorax subor- 

 bicular, with the segment of a circle taken out next the head ; very thickly 

 {punctured, channelled, sprinkled with short yellowish hairs : at the side of 

 each of the four angles is ;i mealy-white spot : the elytra next the lateral 

 margin have two tran.sverse mealy-white streaks or bands, which are con- 

 tinued towards the suture by a l)roader, naked, ferruginous, obscure band: 

 just below the scutellum. on each elytrum, is another mealy stripe, and 

 parallel with the suture is an obscure, naked, ferruginous one : ])odex 

 hairy with the ordinary mealy j^ale spots very conspicuous ; it is sculptured 

 with transverse undulated lines : cubits robust with two stout teeth : a 

 mealy spot marks the ba.se of the posterior legs. [Synonymous with T. 

 piger Fabr. : taken commonly in Ontario.]

In the markings of its elytra this species agrees precisely with that last 

 described, but the upper side of the body, especially the head and pro- 

 thorax, is green ; the latter is of a different shape and less thickly punc- 

 tured ; and the cubit and its teeth are less robust : the podex also is more 

 hairy. These can scarcely, all of them, be mere sexual distinction.s. 



It seems intermediate between T. rotundicollis and T. viridulus. [A 

 variety of T. affinis Gory.]
