the latter part of May, practically none appearing later and there 

 being no conspicuous exudations of pitch. The larvae of I. resini- 

 cola have probably wintered in these pitch masses, resuming activity 

 in the spring and producing at the present time large, fresh looking, 

 white masses of pitch. 



On the 17th larvae collected June 12th had all withdrawn from 

 the surface and were observed lying in the interior of the pitch 

 mass against the wood and apparently in an oval cocoon. They re- 

 mained in this condition until the 24th, at which time the pupae had 

 wriggled to the surface and disclosed imagoes, the exuviae pro- 

 truding part way from the pitch mass. The head and thoracic por- 

 tions of the exuvium are slightly and variably fuscous, quite dif- 

 ferent from the nearly uniform, densely pigmented exuvium of 

 /. inopis O. S. There is no evidence of /. resinicola deserting the 

 pitch mass and making resinous cocoons on the leaves, as is the case 

 with /. inopis (see account of the latter in Journal Economic Ento- 

 mology, 1912, 5: 368-69). 



Cecidomyia ocellaris 0. S. 



Some exceptionally vigorous larvae and one or two puparia of 

 this species were received June 18, 1912, from Miss Cora H. Clarke, 

 Magnolia, Mass. 



The breeding jar containing this material has been under constant 

 observation, and on July 17, 1912, an examination of three puparia 

 showed that each contained a stout, white, apparently healthy larva. 

 There seems to be no indication of an impending transformation. 

 The puparia are oval, stout, brown, more or less irregularly reticu- 

 lated and slightly ridged. The irregular ridged and reticulated 

 appearance appears to be due largely to the arrangement of some- 

 what stouter, dark brown threads, which latter appear to perform no 

 special function. One or two of these puparia were attached at 

 almost right angles to the leaf surface, while a group of four or five 

 lay side by side in a leaf fold. We have obtained puparia repeatedly 

 without securing the midge and take fhis opportunity of expressing 

 the hope that some entomologist will shortly be more fortunate and 

 rear adults.
