726 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Le Conte seems to suggest that the two eastern species may eventually 



be united. Length, 1.5™"^ (.OG inch). 



The mine of this beetle I found under the 

 bark of the southern jiine 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, LS"^-^ (.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. Rypomolyx pinicola he Conte. 



This species was originally described by Couper (Trans. Lit. and His- 

 torical Society of Quebec, 1864), under the name of Hylohius 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; striae composed of large elongate deep punctures. Length, 

 13.5"^"^ (.5 to .3 inch). 



58. Hilipus squamosus Le Conte. 



The genus Hilipus, 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
