156 NATHAN BANKS.

Oct.; Agricultural College, Mich., July; and Mt. Washington, N. 

 H. Fitch described it from New York in July and August. The 

 cocoon is yellowish, and is often seen on pine-needles; the larvae 

 feed on Chermes. 



t'lir.ysopa calif bruica Coquillett. — Pale green or yellowish, with a pale 

 median dorsal stripe in life. Cheeks suffused with red, and often a red dot above 

 on vertex near each eye. Venation pale green or yellowish, pterostignia moder- 

 ately distinct. Pronotum about as hroad as long, sides parallel, not narrowed in 

 front. Wings rather broader than Ch. harrisi, and not quite as acute at tips. 

 The divisory veinlet of third cubital ends usually at the cross-veinlet. Length 

 13-15 mm. 



Described from California, and I have seen specimens from many 

 places; Los Angeles, Tehama, Wanona, San Bernardino, Palo Alto, 

 San Mateo Co., Santa Clara Co. and Siskioii Co.; mostly in July 

 and August, but some in April. Also from Hood River, Oregon, 

 September; Pullman, Wash., July and August; and King's Canon, 

 Ormsby Co., Nevada, July. It is barely more than a variety of Ch. 

 harrisi, but I understand that Hagen considered it a distinct species. 

 It is the most abundant species on the Pacific Coast. 



dirysopa externa Hagen.— Pale green or yellowish, not showing a dis- 

 tinct pale median stripe; cheeks reddish. Venation green, pterostignia not dis- 

 tinct. The pronotum is about as hroad as long, but the sides converge a little 

 forward. The wings are slender and acute at tips; the divisory veinlet ends be- 

 fore the middle of the cell and before the cross-veinlet. The venation is not as 

 dense as in the allied species. Length 11-14 .mm. 



Specimens have been seen from Las Cruces, June, Santa Fe, 

 Aug., and Mesilla, New Mexico and also from Yuma, Arizona, and 

 Palm Springs, Cala. (Feb. 14th). The variation upon which the 

 specific name is based occurs also at times in the allies species, and 

 one of Hagen's specimens, that from D. C, must have been a Ch. 

 harrisii. Nevertheless I have retained the name for those specimens 

 which show the variation in an extreme degree.

. The genus has the venation about as in Chrysopa. The antennae 

 are more widely separate at base than in any of our other forms, and 

 in the male there is an inter-antennal protuberance or horn. The 

 basal joint of the antenna is more slender than in Chrysopa. The 

 species appear to inhabit mountains. Type is M. signoretti. 

 Our three species are separated by the following table :
