so completely leaf -mined as to render them worthless. From leaf- 

 mined blades of Panicum proliferum I reared myriads of Pedobius 

 websteri Ashmead, MS. The whitened tips of the leaves of the Pani- 

 cum were so numerous along the streets of Urbana, 111., as to render 

 them conspicuous objects. 



Many years ago, at Oxford, Ind., I reared Eumetop ia rufipes Macq. 

 from the stems of Panicum crus-gaUi. The larvae were first observed 

 at work in the stems in June, others again in August, the adults 

 appearing August 13. The effect on the stem of the grass is much 

 like that of Meromyza americana on wheat, except that the grass is 

 attacked before as well as after heading, the attack being to the upper 

 portion of the stem. I was not then able to get the flies identified, 

 and no report was ever made of the rearing. 



( { ratomia catalpae Edw. attacks the catalpa trees in southern Indiana 

 and Ohio, sometimes completely defoliating them. The larvae are 

 attacked by Tachinid flies, and the larger portion of them seemed to 

 have been parasitized in this way. Farmers about New Harmony, Ind. , 

 report that the cuckoo also feeds upon them. 



Pseudoanthonomus longulms Dietz (?) was found in the seed pods of 

 Menziesia pilosa, collected in the vicinity of Marlinton, W. Va., 

 probably in July. 



Rhodobsembs 13-punctaims 111. was observed feeding on the half-ripe 

 seeds of the garden sunflower, August 16, 1902. I had previously 

 reared the adult beetle from larva found burrowing in the stalk. 



Schizocerus zahriskei Ashm., adults of which were observed in Illi- 

 nois and Indiana in considerable numbers, appeared to be prevented 

 from breeding in purslane through some cause not clearly apparent, 

 as it was rare that the work of the larvae was to be found. 



Again, I have witnessed the work of some of our Coccinellids in 

 terminating an outbreak of aphides. In the vicinity of Princeton, 

 Ind., late in August, I found a field of red clover that, as was clearly 

 indicated by the appearance of the clover leaves, had been literally 

 overrun with a species of aphis, though there were few of them left at 

 the time of my visit. There were, however, swarms of lady beetles 

 and their larvae and pupae to be found everywhere. The species most 

 numerous were Hippodamia IS '-punctata , II. gladalis, and H. paren- 

 thesis. The leaves of the clover were stunted, blackened, and curled 

 with the cast skins of the aphids scattered plentifully over them. 



Idolothrips coniferum Perg., both adult and larva, were found among 

 stems of rye in July and in stems of Elvmus in August, at Urbana, 111. 



Eurytomocharis eragrostidis How. was observed cleaning its body. 

 To clean the head and thorax the anterior pair of feet was used, and 

 the motions made in doing this can best be illustrated by watching a 

 white rabbit perform the same operation to its face, the quick, jerky 

 motions being similar in the case of each. For cleaning the wings
