ENTOMOLOGY. 
On the larvæ and pupæ of Hololepta and Pyrochroa.— 
Aside from those of direct economic importance, the larvæ of North 
American Coleoptera have received too little attention from entomolo- 
gists, and many of our common beetles are quite unknown in their early 
stages, while others have received passing notice in text-books or agri- 
cultural reports, with here and there a figure, and sometimes a few words: 
of description, more or less vague. Many of the injurious ones have 
been, however, investigated in the most thorough manner by our best 
students of insect life. 
The two species treated of in the present paper have not before been 
given space in our literature beyond, in one case,a short note. It has, 
therefore, been thought fit to furnish detailed descriptions and figures 
for the use of those who may wish to indentify specimens in their pos- 
session. 
HoroLEPTA FossULARIS Say. Plate XXVI, figs. 1, a, b, c, d. 
Color of larva nearly white, head chestnut, prothorax with a trian- 
gular space, occupying most of the upper surface, a little lighter than 
the head. Back with a dark line for the greater portion of the length 
where the viscera show through. 
Form elongate, somewhat flattened ; length 17.5 mm. 
Head castaneous, quadrate, broader than long; above strongly flat- 
tened, with four impressed lines on the front and an impressed space 
near the base of each antenna, from which a line of punctures runs to 
the base. Anterior margin produced, truncate in front, and with a lobe 
over each mandible. Beneath, less flattened, with a broad, deep im- - 
pressed space on the gular region, extending in the form of a narrow 
groove to the base. 
Antenne arising from the sides of the head, immediately behind the 
base of the mandibles, four-jointed, the first joint very short, sunken, 
the second long, the third shorter, subtriangular, with three papillz at 
end, fourth joint again shorter, elongate oval. There are, apparently, 
no bristles, except two short and inconspicuous ones at the tip of the 
last joint. 
Eyes are, apparently, altogether wanting.
