that it becomes impracticable to list them. Outstanding among them, 

 however, are Mr. Hugh B. Leech, through whose courtesy I have been 

 enabled to study all the material belonging to this genus in the collec- 

 tions of the California Academy of Sciences (CAS); Mr. H. Dietrich, 

 who kindly sent on loan 206 examples from the collection of Cornell 

 University; Mr. Edward A. Chapin, through whose cooperation I 

 received for revision 259 specimens belonging to the U. S. National 

 Museum (USNM), Mr. E. A. Dickason of Oregon State College, 

 Prof. R. E. Larson; Mr. L. R. Gillogly; and Mr. J. W. Green. To 

 these gentlemen, as to the many others whose names are not here 

 recorded, grateful acknowledgement is made of the important part 

 which they have played in bringing about the completion of this paper, 



Meligethes canadensis^ new species 



Figure 7Q,a-f 



Male: Length, 2.2 mm, ; width, L3 mm. Oval, somewhat elongate, 

 moderately convex, shining black, with second segment of antennae 

 and segments 1-4 of all tarsi brown; short fine inconspicuous pubes- 

 cence. 



Head strongly transverse, triangular, slightly convex. Clypeus 

 with anterior margin straight. Punctures equal in size to the eye 

 facets and separated by one-half to one diameter, the surface between 

 finely microscopically reticulate. Antennae black, except the second 

 segment pale brown, and the third brownish black, the club of medium 

 size, about twice as long and 2% times as wide as the first antennal 

 segment. 



Pronotum nearly twice as wide as long (1.1 : 0.6 mm.), with sides 

 almost straight in the middle, strongly rounded inwards in front, less 

 so towards the base. Front margin almost straight, except at its 

 extremities where the front angles are slightly promment, little more 

 than half as long as the hind margin. Hind margin extremely feebly 

 sinuate on each side of the scutellum, hind angles obtuse, bluntly 

 pointed. Upper surface moderately strongly convex, feebly explanate 

 towards the hind angles; sides narrowly bordered. Punctures slightly 

 coarser than those of the head, and on the disc equally close, towards 

 the base separated by 1 to 1% diameters, surface between finely 

 microscopically reticulate. 



Elytra a little more than twice as long as the pronotum (1.4 : 0.0 

 mm.), scarcely longer than broad, at base as wide as base of pronotum, 

 gently rounded at the sides and somewhat narrowed posteriorly, the 

 apex of each being gradually rounded off, and having an extremely 

 minute tooth at the sutural angle. Moderately strongly convex.
