 Piceous, moderately shining, similar in form to the preceding, but 



more convex, thorax sparsely punctate, punctures coarse and on the disc 

 more or less fusiform. Elytra deeply striate, striae punctured at bottom, 

 not serrate, intervals subequal convex, the sutural with a row of elongate 

 punctures. Pygidum coarsely cribrate. Body beneath coarsely but less 

 densely punctured than oryzce. Length .10-. 14 inch : 3-3.5 mm. 



In well preserved specimens the surface has fine, short sette as in the 

 preceding, but they are much more apt to be lost. 



Occurs from Canada to Arizona. 



Other species of Calandra have been from time to time introduced into 

 our country by ships from tropical ports, although none have found per- 

 manent lodgment, as far as I am aware. 



COSSOXIDES. 



This tribe as restricted by Lacordaire (Genera vii, 319), appears to be 

 entitled to higher rank than is assigned it by that author, but a discus- 

 sion of the merits of this view would require a revision of the entire family 

 and is not pertinent to the objects of the present essay. 



The groups as established by Lacordaire appear hardly to be of equal 

 value, and some are composed of rather heterogeneous material. The 

 small number of genera represented in our fauna renders it impossible for 

 me to suggest any change in their arrangement that would be at all appli- 

 cable to the larger number of exotic genera. 



Funicle of antennae 4-jointed, tarsi o-jointed Dryofhthorides.

Metasternmn very short, eyes placed on the rostrum . . I ymantides. 

 Metasternum elongate, eyes placed normally Cossomides. 



DRYOrHTHORIDES. 



This group contains in our fauna, but one genus, remarkable for being 

 the only exception in the entire family in which the tarsi are five-jointed. 



Dryophthortjs, Schonh. 

 The antennal insertion is nearer the base than the middle ; Lacordaire 

 calls it submedian. The mesosternum in our species is not narrow, bub 

 much more widely separates the coxse than the anterior coxa? are separated 

 by the prosternum. Lacordaire says, " mesosternum HroiV and "pattes 

 anterieures assez largement separees," and these characters may really 

 exist in D. lymexylon, from which the generic description was probably 

 drawn.
