northward through Canada without a name. L. haematites, with its red 

 thorax, is well known, occurring abundantly on Cratcegus and other 

 blossoms in the spring. Its sexual differences consist in the thorax of 

 the male being much longer than that of the female, and anteriorly- 

 narrowed The unnamed species is similar in size (.18 to. 22 inch in 

 length), and has the same sexual characters, but the thorax and elytra 

 are concolorous, being black, or brownish black, with cinereous pubes- 

 cence. These two species are frequently taken together, and were the 

 thorax of the same color could not be separated by any character yet 

 discovered. I have the unnamed species from New York, Canada and 

 elsewhere labelled subargentata, or si/iiilis, according to the color of the 

 feet, L. stibargentata is, however, a very different insect, though having 

 the same sexual characters. It is much larger (.26 to. 30 inch in length), 

 blacker, more coarsely punctured and sparsely pubescent, occurring more 

 commonly in northern Canada and the Rocky Mountain region to 

 Mexico. In all these species the legs vary from black to rufous, and the 

 colour is of no value. L. exigua does not belong to this group, having 

 different sexual characters ; the male has the last ventral segment convex 

 at middle and impressed at tip, and in front of the impression a mucro- 

 nate tubercle projected backwards ; this, and the black spot on the 

 thorax surrounded by golden pubescence, easily separate it (L. .24 inch). 

 The unnamed species is probably in most collections by some name. 



Leptttra Zebra Oliv. July 6th. Several females taken oviposithig on 

 a white oak stump made the preceding spring. 



Agasphce^-ops nigra Horn. Among a number of Rhyncophora from 

 Vancouver Island, B. C, from Rev. Geo. W. Taylor, there was a speci- 

 men of this singular insect, so like Otiorhynchus sulcatiis that I passed it 

 by as such till the unknown forms were examined. The genus and species 

 were founded on two specimens taken at Mendocino, Cal. This specimen 

 differs a little from the types being a little larger (.34 inch; ; the tubercles 

 on the thorax are not very close, each being about the size of a No. 2 to 

 3 Klaeger pin head, flattened on the top, and bearing a deep puncture ; 

 the elytral intervals are composed of single rows of tubercles equally as 

 large and similarly punctured. On the thorax and elytra there is a pattern 

 of white and golden scales similar to that seen in Hormorus undulatus, 

 but they aie sparser and less conspicuous \ these scales are easily rubbed 

 off, which may have been the case with the types before they were seen,
