specimens, and I afterward captured over 100, some of them fully four 
inches in length. 
Prior to that time I had carefully searched for insects of this descrip- 
tion without success; but now knowing their habits I found them or 
traces of their presence everywhere that the mountain ash was found. 
They are always found near the tips of branches, where by means of 
their projecting thoracic horn they scrape through the soft bark to cause 
a flow of sap which is very sweet, and of this consists their food. When 
discovered they were largely zz copulo and a few days afterward though I 
found traces of their presence everywhere in the shape of scraped ash 
branches, yet not another beetle did I see. 
This shows that the peculiarly modified thorax is not entirely with- 
out value to the insect. Unfortunately my entire collection of Coleoptera, 
the result of several months careful collecting was stolen on my way 
home, and I cannot therefore give the specific name of the insect, which 
however was probably new.

Notes on some Staphylinidae. 
By Grorce H. Horn, M. D, 
Having had occasion to examine a series of Hdaphus, having at 
hand the two types of Z. mztdus Lec., the following result has been ob- 
tained. Of the two types one has two basal fovese on one side and three 
on the other: is there the well marked median basal carina. ‘The side 
on which there are but two foveze is made so very evidently by the fusion 
ef two of the fovee. The second specimen and the one having the label 
is on each side trifoveate. The sutural stria of the elytra is fine but dist- 
inct. To this species cavzmatus Casey should be added as a synonym. 
A certain number of specimens are irregularly foveate and I have 
‘seen one in which there were five foveze, the three regular ones in a row 
and two nearly as large in front placed intermediately with the others, 
On the other hand the transverse impression of the base of the 
thorax, in which the foveze are situated becomes by degrees gradually less 
deep and the fovez gradually smaller so that we notice a gradual dis- 
appearance of the carina which separates the two central fovez and 
finally nearly an entire obliteration of it. Without intending to suggest 
the suppression of the species (/ucw/entus Casey) founded principally on 
the obliteration of the median carina, I merely give my observation for 
the consideration of those who have still more material for study.
