700 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
27. dBdiUi nodubits Fabricius. 
Found under the bark of the pine from June to September. The 
specimens collected about Philadelphia are quite small compared with 
those found in the pine forests of New Jersey. (Bland, Proc. Ent. Soc. 
Phil., i, p. 07.) 
28. JEdilis obboletub Olivier. 
Taken under the bark of pine stumps at and near Philadelphia. Not 
common. (Bland, I. c.) 
29. The pine euderces. 
Eudtrvtb pint Olivier. 
Order Coleoptera; family Cerambycid^;. 
To distinguish this beetle from Psenocerus supernotatus it is only 
necessary, says Dr. John Hamilton, to remember that the prothorax of 
E. pint, instead of being pitted, is longitudinally rugose, and that there 
is on the elytra anterior to the middle a smooth, ivory white, obliquely 
transverse line, which is wanting in P. supernotatus, (Can. Ent., xvi., 
p. 36.) 
A small cylindrical long-horned beetle, having a wide separation between its 
thorax and abdomen, giving it some resemblance to an ant, 0.23 to 0.30 long, of a 
bright chestnut color, with its abdomen and the posterior third of its wing-covers 
black, the wing covers crossed obliquely forward of their middle by a silvery white 
line which does not reach to the suture, and posteriorly on the fore part of their black 
portion a gray band, which is placed in a shallow groove running obliquely and par- 
allel with the silvery line ; the thorax covered with fine impressed lines running 
lengthwise. 
This is said by Olivier to have been found on pines around the city 
of New York, but it is probably a Southern insect. (Fitch.) 
30. Black-horned callidium. 
CaUidium antennatum Newman. 
Order Coleoptera; family Cerambycid^e. 
A flattened long-horned beetle, appearing in May and June, about 
0.52 long, of a deep Prussian blue color, often with shades of green in 
places, its antenna* and legs black, its thorax hairy, and as broad as 
the wing-coven, with the sides strongly rounded and above on each 
side of the middle a little round hollow spot, and its wing-covers rough 
from close shallow punctures. (Fitch.) 
Dr. Harris regarded this as identical with the European C. 
violaceum, deeming the latter to have been probably intro- 
duced into Europe from this country. (Treatise, p. S8.) But 
entomologists now consider the insects of the two continents 
to be distinct species. Ours, doubtless, has the same habits with that
