AMERICAN COLEOPTERA. 195 



or rufo-pioeous, third and fifth intervals more convex, subcostiform, second and 

 fourth intervals moderately densely punctate, moderately hairy; two white 

 fascife one slightly in front of, the other slightly posterior to the middle, ex- 

 tending obliquely forward from the margin, attaining the fifth, rarely the third 

 interval ; a space of velvety aspect, exterior to the fifth interval and posterior 

 to the forward band and divided by the posterior. Body beneath and femora 

 piceous with tseneous tinge, clothed with long white silken hairs. Abdomen, 

 pygidium, tibise and tarsi, rufous. Pygidium with alutaceous surface clothed 

 with short hairs at middle, at sides frequently a white scaly space with longer 

 hairs. 



The male has no anterior tibial spur, and the tibia at tip is very obliquely 

 truncate, the inner face being moderately broad. 



This species occurs more especially iu the Northern States as far 

 west as Missouri. 



T. texanus, n. sp. (Candeze mss.)- — Body above and beneath black, shi- 

 ning. Head densely punctulate. Thorax moderately densely punctured, and 

 with the head, clothed with short erect pubescence. Elytra with intervals three 

 and five more elevated and smoother, two and four flat, moderately densely 

 punctured and pubescent; two oblique white bands and lateral velvety spot as 

 in piger, frequently also a subscutellar short white line, and another on the 

 second interval. Pygidium alutaceous pubescent, a white space on each side. 

 Body beneath and legs black, moderately hairy. Similar in size to piger. 



The male has the anterior tibise very stout, the inner face broad and without 

 terminal spur. The thorax equally punctured and with whitish hairs. The 

 pygidium is much less conspicuously pubescent than in the female. 



The female has the thorax more coarsely punctured and a smoother space 

 within each hind angle. The angles have a narrow white space on each, and 

 the hairs are longer than in the male and yellowish. The pygidium is also 

 more densely hairy, the hairs yellow and longer than in the male. 



In both sexes the thorax is less densely punctured than in piger. 

 Occurs in Texas and Florida. 



T. aflinis. Gory. — Body above and beneath and legs black, with slight 

 tinge of bronze, disc of elytra usually paler. Head moderately densely, thorax 

 sparsely punctured, sparsely pubescent. Elytra with intervals three and five 

 slightly more convex, two and four very sparsely punctured; two white bands, 

 subsutural white line and velvety space as in te.ranus. Pygidium with lateral 

 white space moderately densely alutaceous and pubescent. Usually smaller 

 than piger. 



Resembles piger ^ but with a smaller and less punctured thorax, and 

 differs especially in the sexual characters and the very sparse punc- 

 tures of the second and fourth elytral intervals. 



In the female the pygidium is slightly flattened near the tip. 



Occurs from Canada and New Hampshire to Georgia. 



T. bibens. Fab. — Body above, beneath, and legs bright metallic green, 

 elytra rufo- testaceous with slight aeneous lustre. Head densely punctured. 

 Thorax more coarsely but less densely punctured, clothed with short erect hair.
