dish, annulate with black. Thorax nearly twice as long as wide at base, 

 convex, narrowed in front; disc rugosely punctate and with three feeble 

 longitudinal carinae, the grooves between them wide and rather deep; base 

 truncate, the transverse ridge about one-fifth in front of base, more or less 

 sinuous, forming an obtuse angle at middle and bent obliquely forward on 

 the sides. Elytra at base subtruncate nearly one-half wider than thorax, 

 stria? punctate. Length 6.8 10 mm.

 on dead brandies. Southern States as far north as District of 

 Columbia. Texas and Mexico. 



II. ORMISCUS Water-house, 1845. (Gr., "neck.") 



Small, snbcylindrical species having the besik broad, fiat, not 

 longer than head; antennae alike in both sexes, scarcely reaching 

 the base of the thorax; eyes rather large, oblique; thorax strongly 

 narrowed behind the transverse carina, which is prominent, par- 

 allel with the base, and ends each side in a small cusp. One 

 species occurs with us. 



We have followed the "< Msissificaf ion" in our treatment of this 

 and the next two genera, though Dr. Karl Jordan and Charles 

 Schspffer have recently expressed more or less definitely views in 

 favor of uniting Toj-otropis, Gonops and Eusplujnis with Onuis- 

 cus, on account of the failure of the characters used by 

 LeConte in some of the numerous tropical species of the 

 group. The spur-like process at apex of middle and hind 

 tibise of male Gonops is said to be present also in some tropical 

 Toj'Otropix, while in others only the middle tibise are so armed. 

 The position of the antebasal carina of Ensphyrits is peculiar, in 

 its absolute described relation to the base, to our eastern species 

 only and variable in others. The deeply cleft claws of some 

 Toj-ofropix gradually become more simply toothed in other 

 species; so that those who have worked with the species of the 

 world sire puzzled to know what characters can be relied upon 

 to sepsirsite these closely allied genera. In our limited fauna, 

 however, the distinguishing characters as set forth by LeConte 

 are sufficient, and are therefore followed in the absence of any 

 better complete classification of the group.

Oblong, subcylindrical. Brownish-black, mottled with spots and bands 

 of ash-gray pubescence, the most prominent of which is a band before the 

 middle of elytra with a spur forward along the suture to scutellum and an- 

 other each side to humerus, these often abraded. Thorax subquadrate, one-
