bish in fields and gardens, where it may be found early in Spring and 

 late in the Autumn. I have always supposed that this species bred 

 in some common weed. 



Pandeletejus hilaris Hbst. is common on beech trees in June, a 

 few pairs observed in copula at this time. According to Harris 

 the larvae live in the trunks of the white oak. 



Scythropiis clegans Coup, appears sometimes in great abundance 

 in the latter part of April continuing in constantly decreasing num- 

 bers into the middle of July, upon the foliage of pine trees, occurring 

 most commonly at Ithaca, N. Y. , on the white pine {^Pbius strobiis). 

 Individuals from a single locality exhibit a great variety of colora- 

 tion. In the great majority the normal ground color is a rather 

 bright fawn, tinged with a more or less coppery lustre, some are 

 decidedly cupreous, even brilliant, inclining to a pinkish hue, and 

 others are of an equally brilliant metallic green. In specimens taken 

 late in the season the scales which prociuce this variety of coloring 

 ha\'e been worn off, or have faded, leaving the body a nearly uniform 

 dull cinereous. In such individuals the humeri have become de- 

 nuded, and the ground color is then much the same as the sutures, 

 which are normally nearly white. One specimen taken early in the 

 season retains its deciduous mandibular appendages. 



Ithycerus noveboracensis Sch. is known to breed in the twigs of 

 bur-oak, and the beetle is injurious to the buds of a variety of fruit 

 and forest trees. All the specimens that I have ev^er taken were on 

 beeches, and I suspect that this is a favorite food-plant for both 

 larvae and beetles. Mr. W. H. Harrington states (Ann. Rep. Ent. 

 Soc. Ont. for iSSo, p. 52) that he has frequently found the beetle 

 on beeches in June, the sexes copulating at this time. It also occurs 

 in May and July. 



Apion nigrum Hbst. occurs cjuite commonly on the leaves of 

 the locust {Robinia pseiidacacia). The leaves are often seen riddled 

 with minute holes, and as the /Ipions and Agrihis egemcs are the 

 only insects observed by me in any numbers on this tree, and the 

 former occur in the greatest abundance the blame naturally attaches 

 to them. July. 



A. rostriDU Say occurs literally in thousands on Baptisia tinc- 

 toria, the wild indigo plant, and according to LeConte (Rhynch. 

 of America North of Mexico, p. 411) on B. leiicantha also. It may 

 be found in this neighborhood in May and June. 



Apion fraterniun Smith, I have observed sometimes in great 

 numbers on the leaves of two species or varieties of Lespedeza. 

 July and August.
