HARPALIN/E 131 



H. oodioides Chd. About the size of cautus Dej., which it much 

 resembles and it is similar in coloration; antennae, palpi and tarsi dark 

 ferruginous, the thighs browner; head slightly smaller, the prothorax 

 less convex, more deeply sinuate at apex, a little more narrowed anteriorly, 

 the posterior part of the sides somewhat less rounded, very feebly de- 

 pressed above; base very slightly rugose, the basal foveae narrower and 

 longer; elytra less convex anteriorly but sloping more abruptly toward 

 tip, less oval, parallel, the humeri more nearly right-angled and strongly 

 denticulate; intervals flatter, very finely micro-reticulate in the male, 

 the female unknown. Length 9 mm. " Terre de Rupert." 



No remarks are appended to give any further clue to the true 

 position of this species, which still remains unknown; it probably 

 belongs among the small-headed species at the end of either the 

 viduus or fraternus group. 



Pteropalus n. gen. 



A few species such as Harpalus mdpeculus Say and dichrons Dej. 

 and Feronia autumnalis Say, have ever been a source of taxonomic 

 discomfiture, being shifted from one genus to another until they 

 have finally brought up in Harpalus, in spite of recognized incon- 

 gruity. LeConte assigned them to Bradycelhis and in truth 

 autumnalis does form a genus near Bradycelhis, but vulpeculus and 

 dichrous must form a genus perhaps having really greater affinity 

 with the Selenophorids than with Harpalus, for which the above 

 name is suggested. The prismatic opalescence of the elytra is a 

 peculiarity of importance, well developed also in many Selenophorid 

 groups but unknown in Harpalus, and the apically expanded ligula 

 and externally prolonged paraglossae also show that these two 

 aberrant species cannot remain in that genus. The slender hind 

 tarsi, with a very long basal joint a peculiarly constant character 

 in the Selenophorini also betray a wide departure from most of 

 the genus Harpalus, though there are some species of the pennsyl- 

 vanicus group approaching it very closely in this respect, except 

 that the upper surface is there more or less pubescent, as it is in 

 the Selenophorini. The mentum is more strongly and constantly 

 toothed than in Harpalus and the general habitus of the body quite 

 different. We apparently have the four following species: 



Sides of the prothorax rather strongly converging and broadly sinuate 

 posteriorly, the basal angles right and very sharply marked, not 

 even blunt at tip. Body oblong-suboval and very moderately
