THE CANADIAN ENTOMOLOGIST. 113 



in their original positions. The first week in the following July I visited 

 the place prepared to search for it, and soon found the course it had 

 taken, and by carefully tracing for about eighteen inches, it was at length 

 found inclosed in a cell of tough material, seemingly humus and leafy 

 debris cemented by some secretion of its own. It made quite a large 

 tunnel, eating the roots of the grass that formed a thick sod overhead, 

 and built its cell about three inches below the surface. It was in a 

 meadow, and there were no trees nor stumps near. I brought it home, 

 being careful to not break the cell, and it shortly developed an average 

 sized female imbricomis. From this it seems that some of the larvse 

 of this species of Frionus, like those of several Elateride species, bore 

 through the earth, feeding on the roots of such grasses and plants as they 

 fancy, which is confirmatory of the observations of Mr. C. V. Riley on 

 the habits of a smaller form, considered a variety of this, that occurs 

 abundantly on the treeless prairies of Illinois and other western States 

 {Missouri Reports 2, p. 89). At the same time it is well established that 

 other larvae of this species live in both the living and the dead roots of 

 trees, thus showing a large latitude of habit. 



ClytantJiJis albofasciatus Lap. Is raised both from grape vines and 

 from hickory limbs. There are two color forms produced indiscrimin- 

 ately that are so different in appearance that judged by color alone would 

 form two species. The one is entirely black, with the usual anterior and 

 posterior white bands on the elytra ; the other is black with the antennae 

 brown ; the part of the elytra anterior to the posterior white band, the 

 femora, the coxal part of the prosternum, the meso and metasternum, 

 rufous. This is exactly the color of the more plentiful form of Cyrto- 

 phorus verrucosus, and it is not difiicult to confuse them. They may be 

 readily distinguished by the compressed thorax and the spinfes of the 

 antennal joints of the latter, as pointed out to me by Dr. Horn. The 

 same color variation occurs in Psenocerus supernotahcs. A few specimens 

 of which taken on the wild gooseberry were entirely black, except the usual 

 white markings on the elytra, and so different is the appearance that it 

 required close attention to other characters to be convinced that they were 

 the same species. 



Physojiata unipundata Say. Mr. Caulfield, in the March number of 

 the Entomologist,- gives a very good account of the form P. ^punctata. 

 Those finding imipunctata would do good by making known its food
