Criocephalus agrestis. 



parts of our continent from the Atlantic to the Pacific. Its larva 



feeds on the wood of living pine 

 trees, boring its way out to the 

 surface. 



Pachyta liturata Kirby (Fig. 26) 

 is not so common as the preced- 

 ing, but is found over practically 

 the same wide territory. It is 

 much shorter, being only three- 

 quarters of an inch long, and the 

 sides of the body are not parallel, 

 as in that species. The wing 

 cases are light yellow, faintly 

 marked with black, and when 

 folded the insect is very much 

 wider and thicker at the middle 

 of the body than at either extrem- 

 ity. On each side margin of the thorax is a small spine. 



Beetles belonging to several other families besides those I have 



mentioned are found in Labrador. Byrrhus Americanus Lee., 



a small, convex, silky, greenish black beetle 



was taken by Professor Packard on the 



stems of the "Labrador tea," and several 



specimens of this and another smaller, close- 

 ly allied kind have been sent to me. The 



beetles of the family Byrrhidse are common 



in northern climates, living in mossy places, 



around the roots of plants, etc. 



Then there are some small snapping 



beetles of the family Elateridse, and some 



Buprestidae (whose larvse are wood-borers). 



Also some species of weevils which are 



bark-borers, and a few beetles which we 



might expect to find upon the blossoms of 



plants. The regular leaf and plant beetles, 



however, are conspicuous by their absence, 



though very likely some of them may be 



found in Labrador. None were found by 



Dr. Packard, and I have not received any. 



There is no doubt that there are many species of Labrador 



beetles besides those already known. The additions made to former 



records by Dr. Grenfell's friends show this clearly enough, and if 



these men continue the search, we can probably look for many 



more important captures from this very interesting region.
