INSECTS INJURIOUS TO THE BUTTERNUT. 
(Juglans cinerea.) 
AFFECTING THE TRUNK AND LIMBS. 
1. The spotted leptostylus 
Leptostylus macula (Say.) 
Order Coleoptera ; family Cerambycid^e. 
Under the bark of old decaying trees, a longicorn larva, changing to a pupa in its 
cell and early in July giving out a small thick long-horned beetle of a brown or chest- 
nut color with the sides of its thorax and a band on its wing-covers ash-gray, the 
latter sprinkled over with coarse punctures and large blackish dots, the thorax on 
each side of its disk with a black stripe interrupted in its middle. Length, 0.25 inch. 
Dr. Fitch, in his third report, states that the bark of old trees will 
sometimes be found everywhere filled with these grubs, which in the 
month of June may be seen changed to short thick pale-yellow pupae, 
with a few perfect insects that are newly hatched and have not yet left 
the tree. Mr. Harrington has taken specimens on the butternut, but not 
so frequently as on the bitter hickory. 
2. Gaurotes cyanipennis Say. 
This beetle was observed by Mr. F. B. 
Oaulfield pairing and ovipositing on the 
butternut. (Can. Nat., xiii, p. 60.) 
The beetle. — Black; antenna? and feet testaceous; 
elytra blue. Body black, tinged with cupreous, 
punctured ; head densely punctured ; a longitudi- 
nal, obsolete, impressed line; antennas rather 
shorter than the body, testaceous; trophi piceous- 
yellow; thorax impunctured; an obtuse tubercle 
each side; scutel black; elytra violaceous blue; 
puuctures numerous, small, profound; tip trun- 
cate; humerus rather prominent; feet testaceous. 
Length two-fifths of an inch nearly. In form of 
body, it very much resembles Leptura collaris and L. 
virginea, to which genus I would have referred it, 
but for the small thoracic tubercles. (Say). Fig.

Smith and Marx, del. 
3. Cryptorhynchus parochus Say. 
Several larvae and pupae of this weevil have been found by Mr. F. G. 
Schaupp under the bark of a butternut in Brooklyn, L. I. The 'dura- 
tion of the pupa state was from fourteen to sixteen days. 
Beetle.— Brown variegated; tibiae not angulated at base; thighs feebly bidentate; 
the teeth small and distant. Length 6to6.5 mm . Claws simple,divergent. (LeConte.)
