the apical margin at the sides broadly lobed ; disk with two small 

 and very widely separated foveas near the basal margin but not 

 otherwise modified. Elytra large, oval, somewhat less than three 

 times as long as the prothorax and twice as wide ; sides sub- 

 parallel, broadly, evenly arcuate ; humeral plica broad and indefi- 

 nite, the subhumeral impression large but feeble ; fovese deep, 

 perforate and approximate ; suture not beaded, the impressions 

 obsolete. Mesosternum finely and strongly carinate. Meta- 

 sternum large and long. Hind coxae rather narrowly separated- 

 Legs stout and well developed ; two anterior femora strongly, the 

 other four moderately, clavate ; hind tarsi cylindric, the joints 

 compactly joined, the first four equal in length; ungues slender 

 and moderately arcuate. Length 1.65-1.9 mm. ; width 0.7-0.85 

 mm. 



Canada (Ottawa), New York, Pennsylvania and Iowa (Iowa 

 City). A rather common species and more than usually variable 

 in point of size. The parapleurse of the mesosternum are tumid, 

 as usual, and have a few sparse hairs. The above description is 

 drawn from the female, but sexual diflTerences are not obvious in 

 the series before me, and the male has no striking secondary 

 characters. 



It appears to be certain that the Euconnus calvus of Sharp, re- 

 cently described in the " Biologia " from Guatemala, is not only a 

 member of this genus, but that it is exceedingly closely allied to 

 rasus. 



arOCTOPHUS n. gen. 



This name is proposed for a large species, densely pubescent 

 throughout, having in general the structural characters of Eucon- 

 nus, but exhibiting difierences in antennal, labral and crural 

 features which seem to demand a generic separation. The head 

 is large, the antennal cavities widely separated b}^ the simple de- 

 clivous front, the clypeus simple and rectilinearly truncate, its 

 plane of inclination nearly the same as the front, from which it is 

 separated by a feeble transverse depression joining the cavities. 

 Labrum large and transverse, its anterior margin very deeply 

 sinuate at the middle. Mandibles and eyes well developed. 

 Palpi missing in the type. Antennae moderate in length, with a 

 clearly defined 5-jointed club. 



The prothorax is nearly as in Euconnus but without trace of
