resemblance to that published by me of Xenorhipis (Trans. Am. Ent. 

 Soc. 1882, pi. iv., fig. 7, 8). If the two should prove identical, the name 

 given by LeConte (Proc. Acad. 1866, p. 384) should have priority. 



L. suturalis Westvv. occurs at Cordova, Argentine RepubHc. 



Cyrtophorus gibbidus Lee. (niger % Lee.) On examining this insect 

 with Dr. LeConte, we were convinced that it does not differ in any respect 

 from Microclytus gazellula Hald. 



Leptura coccinea Lee. After refreshing my memory by a glance at the 

 type in Mr. Ulke's cabinet, I visited the Agricultural Department and 

 from force of habit glanced over the plates of Ratzeburg's Forst-Insecten> 

 and I at once recognised a great similarity between my mental image of 

 coccinea and rubrotestacea. On comparisons being made by Messrs. Ulke 

 and Schwarz, the two were found identical. As the specimen was reported 

 to Mr. Ulke probably in error as from California, the name should be 

 placed as a synonym of testacea Linn. ( = rubrotestacea 111.) and dropped 

 from our lists. 



L. atrata Lee. After a careful examination of the very old unique in 

 the cabinet of Dr. LeConte, the latter agreed with me that it was a speci- 

 men of proxima in which the customary black tip had extended, covering 

 the whole elytra.

During the summer of 1882 a few of the ash trees on the college lawn 

 became infested with a Saw-fly worm which for a few days threatened to 

 be quite serious. I made a few trials of London purple on the trees 

 most seriously infested, but before I had gained results from many trees 

 or had completed a study of the larvae, they suddenly disappeared. So
