Cymatodera bicolor and C. nndnlata are both attracted to 

 light, the former more commonly than the latter. 



Prioccra castanca, a beautiful and unique species which seems 

 to be quite a rarity. All specimens were taken at Hey worth 

 under bark on just such logs as cited for Zcnoa picca. The 

 Prioccra are sluggish and easy to capture ; found July i2th 

 and 1 5th. 



Clcrns qiiadriguttatns, two specimens of limbs of fallen wal- 

 nut, the trunk being badly infested with Molarchus bimaculatus 

 and Cryptorhynchus parochus , upon the larvae of which the Clcrns 

 may possibly feed. 



Hydnoccra longicollis was taken at light. This species has 

 been bred by C. F. Baker from galls of the hymenopterous 

 Enura silicis-nodus walsh, at Fort Collins, Col. 



Cupes concolor was taken but once at lamplight indoors. 



Aphodins concavits, a single specimen flying in open field in 

 August. Mr. Wickham states that he finds two or three every 

 year at Iowa City, la. ; it occurs as far south as Albuquerque, 

 N. M., where he found one several years ago. May not this 

 differ in food habits from others of this genus ? 



Purpuriccnus a.vi/laris, one dead example found in hickory 

 stump July 2 jth, whose legs had been attacked by a fungus 

 growth. 



Phyllotreta armoracicc Koch, a male specimen taken May 5th 

 on blossoms of horseradish growing in the garden. This intro- 

 duced species has been previously reported from Guttenberg, 

 la., Chicago, near the Columbian Exposition, and at Okauchee, 

 Wisconsin. 



Mycetochares fraterna was quite common at the lights near 

 Hey worth. 



Zonitis bilineata, taken but once on mullen. The species was 

 described by Say from the plains of Missouri, and, according to 

 Riley, zonitis is known to develop in the cells of Ostuia and 

 Anthidiuiii, and to have a coarctate larvae like that of Sitaris. 



Gnathotrichus matcriarius is said to infest pine, but have on 

 two occasions taken it on walnut.
