172 Notes on Insectivorous Coleoptera. 



the former as of the latter. In the crop were a few hairs 

 of a caterpillar and much half-digested muscle, with spores 

 of fungi, a little epidermis of some graminaceous plant 

 and a few pollen grains of Oompositae. In the stomach 

 was a great deal of chyme, with fragments of the wings 

 and tarsi of some minute dipter, more pollen of Oom- 

 positae and some vegetable parenchyma, apparently de- 

 rived from unripe seeds of grass. In the ileum and colon 

 these last mentioned tissues predominated, although the 

 latter contained also a large quantity of pollen of Com- 

 positae indistinguishable from that of ragweed (Ambrosia) . 

 Here were also found two feet of a larva, — possibly of the 

 previously mentioned caterpillar. It is worthy of notice 

 that these Harpali were full of eggs, of which there were 

 about six in each abdomen. The crop of the second speci- 

 men, taken at Normal, in September, was distended with 

 a brown, oily fluid, containing no recognizable -material. 

 In the intestine was a small mite and considerable vege- 

 table parenchyma, apparently derived from some young 

 seeds or ovules of plants. A little parallel- veined vege- 

 table tissue was also seen, evidently derived from grass. 



Harpahis herhivagus. — A specimen of this beetle, taken 

 by Mr. McBride, in July, was filled with cryptogamic vege- 

 tation which had the form of a dense mat of slender branch- 

 ing tubes enclosing many spherical cells. This, Professor 

 Burrill, to whom one of the slides of this material was re- 

 ferred, regarded as a fleshy or cartilaginous fungus with 

 Palmella cells, although he thought that it might have 

 been derived from a lichen. A second specimen, obtained 

 by Mr. Webster, in March, had evidently been feeding on 

 the young shoots of grass. 



Cratacanthus duhius. — One of this species, taken at 

 Normal, in August, contained no apparent food except a 

 few spores of fungi. In the stomach were great numbers 

 of Gregarina, apparently of the same species as those found 

 in Harpalus pennsylvanicus. In the colon, especially., 

 scores of these parasites in the "resting state" formed con- 

 siderable masses which half filled the intestines. 



Evarthrus colossus. — One of this species, taken in Sep-
