ventral row on each side of the ventral plate. Length 7-10 mm (.28 to 

 .4 inch). 



Pupa. Body rather thick white. Antennae passing around the bent 

 knees (femero-tibial joints) of the first and second pairs of legs, the ends 

 scarcely going beyond the middle of the body. Elytra with five or six 

 rather deep, longitudinal creases. The salient points of the body armed 

 with piliferous warts. Abdominal tip square at the end, with a stout, black 

 spine projecting from each side. Length 6 mm (.24 inch). 



The parent insect has a uniform, deep prussian blue color with greenish 

 reflections on the head and an elevated line near the outer border of each wing 

 cover. It is a rather stout, rounded flea beetle about '/s of an inch long. 



Life history. The larvae are abundant skeletonizing alder foliage in 

 July and even as late as August and into September, though beetles begin 

 to predominate in the latter months. Dr Lintner states that the pupae are 

 normally found under moss coating adjacent rocks ; hundreds were brought 

 to light lying loosely in the mold and without the slightest indication of 

 cocoon or cell. They were about an inch below the surface and distinctly 

 yellow in color, though Dr Packard has characterized them as white. 



Distribution. This species has an extended distribution according to 

 Dr Horn, who states that it occurs in the entire northern portion of the 

 continent, as far south as Pennsylvania, thence westwardly, extending over 

 the western plains to Texas and Arizona, and on the Pacific slope from 

 Alaska to Mexico. 



Attelabus rhois Bohe. 



Peculiar, thimblelike rolls of leaves on alder, hazel, and sumac, may be the work of 

 this species. 



This dull reddish beetle has the body clothed with a short yellowish 

 down, and is about ',5 inch long. The &<g% is nearly spheric and about 1/25 

 inch in diameter. 



Life history and habits. The singular, thimblelike rolls of this weevil 

 may be found in June and July on alder and also on hazel and sumac. 

 When about to lay her eggs, the female begins to eat a slit near the base 

 of the leaf, on each side of the midrib and at right angles to it, so that the 

 leaf may be folded together. Before rolling, she gnaws the stem nearly off, 

 so that the rolled portion of the leaf will dry in perhaps a day and drop
