726 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
Le Conte seems to suggest that the two eastern species may eventually 
be united. Length, 1.5 ,m " (.00 inch). 
The mine of this beetle I found under the 
bark of the southern pine at Montgomery, 
Ala., the beetles taken therefrom having 
been submitted to Dr. Horn for identifica- 
tion. The figure well represents an average 
mine. The primary gallery is nearly 4 inches 
long, very narrow, somewhat sinuous, end- 
ing at one end in a broad cell from which 
three or four secondary galleries pass off. 
About twenty secondary galleries pass off 
on each side at right angles to the main gal- 
lery, but not all in the same plane, as the 
figure shows; they are rather short, less 
than an inch in length, and sometimes end 
in a broad, irregular cell; the round dark 
spots in the figure indicate the holes in the 
bark for the exit of the insect. It appears 
to be a common pest in the Gulf States. 
56. The two-crested southern timber-beetle. 
Carphoborus bicristatus Chapuis. 
In Georgia occurring under pine bark, ac- 
cording to Le Conte. Length, J.8 mm (.07 
inch). 
The five following Scolytids also occur on the pine. The notes are 
taken from Le Conte's essay on the Rhynchophora, or weevils of the 
United States.

57. Hypomolyx pinicola Le Conte. 
This species was originally described by Couper (Trans. Lit. and His- 
torical Society of Quebec, 1864), under the name of Hylobius pinicola. 
The body is elongate, ovate, broader behind, the eyes small, elytra 
oval, convex ; the beak is as long as the prothorax, rather stout, slightly 
curved; the prothorax is rather small, subserrate on the sides, very 
coarsely punctured, thinly clothed with coarse hair, carinate in front ; 
the elytra are densely punctured, mottled with small spots of yellow 
hair; strire composed of large elongate deep punctures. Length, 
13.5 mm (.5 to .3 inch). 
58. Hilipus squamosii8 Le Conte. 
The genus Hilij)us, says Le Conte, largely developed in tropical 
America, is represented by a single rare species found in Georgia and 
Florida, where it occurs under pine bark. It differs from Hylobius in
