AMERICAN COLEOPTERA. 343 



A very slouder species more elongate than uni/asciafa, which it 

 otherwise resembles in form. Its elytra are more coarsely punctured 

 than any species in our fauna, and may be readily known by the color 

 and the white markings. 



Specimens were collected by Mr. G. W. Belfragc, at Waco, Texas. 



SCOTODES, Esch. 

 Within a few days I have received from Europe types of >S'. annuln- 

 tiiK, Esch., and find on careful comparison that the genus established 

 by me for our species, Anelpisciis, must be suppressed. At the time 

 (Trans. Ent. Soc. June, 1870, p. 88) I stated that Scotodcs, was un- 

 known to me in nature, and as but one species was known from Rus- 

 sia and the figure by Duval indicated an insect so different from our 

 own, I felt justified in assigning provisional differences with the hope 

 of having comparisons made and characters of more moment noted. 

 Not only do the genera agree but the species also arc very clsoely 

 allied. As compared with annulatus our species has a broader tho- 

 ra.K not sinuate on the sides and the hind angles consequently less dis- 

 tinct, the elytra are punctured at the apex and become gradually more 

 scabrous toward the base. In both species the elytra are clothed 

 with similar pubescence, arranged in our species in two tranverse 

 bands (at middle and at apical three-fourths) and in annulatus, in 

 three. The sculpture in the latter species is similar over the entire 

 surface and is not coarsely scabrous. Ilind tibiae arcuate, amcrkanu* 

 % ; straight in annulatus % .

 The type of Scotodes annulatus, Esch., was kindly presented by Mr. 



Alex. Frv, of England. 



TRIPLAX, Payk. 

 T. (Tritoma) aulica, n. sp — Ovate, shining; head and tliorax above, and 

 beneath, legs and humeral spot yellow ; body beneath black, tip3 of abdomen 

 yellowish. Head and thorax sparselj' punctured. Antennae yellow, club black 

 third joint equal nearly to the three following. Elytra black, humeral spot yel- 

 low, surface with striseof fine punctures, intervals finely punctulate. Body be- 

 neath sparsely punctulate. Tibiae moderately dilated. Length .12 — .18 inch; 

 3 — 4.5 mm. 



The humeral spot is moderate in size and similar to that of humer- 

 alis, involving the epipleurae and extending inwards slightly within 

 the third stria and somewhat pointed behind. It is the only species 

 in our fauna with yellow thorax and humeral spot together. 



Specimens in my cabinet were collected and kindly presented bj 

 Dr. S. V. Summers, of St. Louis, Missouri.
