late punctures in the former genus, not distinct in the latter. The 

 S(!tigerous punctures of the side of the thorax are two in number, 

 the first situated at the point of greatest width, the second mid- 

 way between this and the hind angle. The thorax is not wider 

 than the head between the eyes 



The males have the anterior tarsi slightly dilated, and from the 

 anterior angle at the inner side of the joints 1-3 proceeds a brush 

 of fine silken hair. 



Euphoiiicus Horn, is founded on Lachn. pubescent Dej., and 

 the only characters separating it are those given in the table. 



Group Anchonoderi. 



The eyes are not prominent. He:ul oval, slightly narrowed 

 bt'hind the eyes, front horizontal. Elytra not margined at base, 

 the apices rounded, surface striate, eighth stria distant from the 

 margin and with the ocellate punctures feeble, dorsal punctures 

 three but fine and indistinct. Thorax cordate as wide as the 

 head, lateral setigerous punctures situated at the point of greatest 

 width and in the hind angle. 



The anterior tarsi of the males have three joints slightly dilated, 

 and with squamiform papillae and ciliate at the side. 



Anchonoderus \^ represented in our fauna by one species from 

 Texas. 



Group Atrani. 



Head oval, more elongate than Anchonoderus, the eyes not 

 prominent. Antennas with but three joints glabrous, the fourth 

 punctured and pubescent as the fifth. Thorax cordate, a little 

 broader than the head, the seta3 in the normal position at the 

 side and in the hind angles. Elytra margined at base, the apices 

 rounded, surface striate, the ocellate punctures well marked, dor- 

 sal punctures not distinct. 



The sexual characters are as in Anchonoderus. 



This group contains in our fauna but one species, Atranus 

 pubescens (Dej.). 



Tribe XXII.— CTEXODACTYLIIVI, 



Antennas slen'der, base free, three basal joints glabrous, first 

 joint stouter, as long as the next two, 3-11 equal or nearly so.
