acuminate humeri, which this form certainly has not. Two cliarac- 

 ters he mentions — the elevated apex of the tylus and the unspotted 

 venter — are found in several allied species. To answer these few 

 characters, the only ones given, it is necessary to select some species 

 in this section of the genus, that is larger than tridiginus, with the 

 apex of the tylus elevated, the humeral angles acute and the median 

 row of black spots on the venter wanting. The form placed as 

 impictiventris above is the only one known to me that does this.

I have recently received from Rev. G. W. Taylor two females 

 taken in Vancouver Island that answer in every particular to Dr. 

 Uhler's description, except that in one the rufous flecks on the ven- 

 ter are wanting and in the other almost obsolete. I have no doubt 

 but that this is the insect described by Dr. Uhler. Comparing these 

 two specimens with a long series of infiatus, I find a few points for 

 distinguishing the two species that seem to be constant. The antenna} 

 in conspersus are rufous, with the apical two thirds of the fifth j(jint 

 blackish ; in injiatas the apical two joints are dusk}' except at base. 

 In conspersus the second joint is distinctly siiorter than the third ; 

 in in.flatas these joints are subequal. In conspersus the scutellum 

 is more convex on the base and narrower toward the apex than in 

 inflatus, and has the extreme tip slenderly edged with white and 

 obviously depressed ; the latter character, however, I imagine may 

 not be constant. In conspersus the legs are conspicuously dotted 

 with black; in injiatas they have but about four black points in a 

 row on the lower surface of the femora, and these may become pale 

 or almost ol)solete. The above characters will sufficiently distinguish 

 these forms as at present known. It would not be surprising if 

 further collecting in intervening localities should bring to light 

 intermediate forms connecting these two species.

xV neat little species, of which I have seen but very few examples. 

 The only one now in my collection was taken in Ohio by the late 

 Dr. Kellicott. The small size, depressed form, and the pale mar- 

 gins of the pronotum, bordered within by a blackish shade, will 

 sufficiently distinguish this species. Dr. Uhler records it from 

 Massa(;husetts, Rhode Island, Pennsylvania, Maryland and the 

 District of Columbia, Mrs. Slosson has taken it on Mount Washing-
