157. Glyptoscelis hirtus Oliv. 



158. Scythropus elegans Couper. 



159. Rylohiiis stupidus Schouh. 



160. Pissodes ajffinis Kaud.

163. Podapion gaUcola. (In galls on small limbs (^-| inch in diame- 

 ter) of Pinus resinosa. June 25. (W. H. Harrington in letter.) 



Wi. Dryoewtes affaher. Mannh.) June 25, the cones of Pi7ius resinosa 

 were found frequently inhabited by Dryocoetes affaber {f), both beetle 

 and larva. Tbeir attacks were readily noticed by the small aborted 

 €ones. The terminal shoots of branches seemed also sometimes infested 

 by the same beetle. I inclose a specimen of the beetle for your deter- 

 mination. It seems larger than a beetle which I found a few years 

 ago boring the terminal shoots of white pine, and which you deter- 

 mined as D. affaber. (W. H. Harrington in letter.) 



165. Gryptocephalus schreibersii. (W. H. Harrington in letter.) 



166. Pytho americanus. In shallow cells under back of old logs and 

 stumps. (Harrington in letter.) 



Order Lepidoptera. 



167. Another span worm, living on the moss on pine trees, and found 

 alive in Cambridge, Mass., in January, by Mr. Hill, is closely assimi. 

 lated in color to the moss itself. 



168. Also a handsome noctuid caterpillar we have found on the pitch- 

 pine at Salem, Mass., which is red, marked with yellow, and would be 

 readily overlooked from its mimicry of the red twigs of the pine. It may 

 be the larva of a species of Trachea, and may represent the Trachea pin- 

 iperda of Europe. 



169. Dr. Hagen has observed pine needles hollowed by an unknown 

 Tineid. (Can. Ent. xii, 121, 1880.) 



Order HEMfPTERA. 



170. Ghermes pinicorticis H. Osborn, Iowa Ag. Report, p. 96, 1881.
