AMERICAN NEUROPTERA. 147 



at tips; the divisory veinlet of the third cubital cell ends plainly heyond the 

 cross-vein. Length 16 mm. 



One specimen from Las Vegas, Hot Springs, New Mexico, Aug. 

 5th (Barber and Schwarz). The type is in the National Museum 

 collection, also from Prescott, Arizona (Oslar). The black on the 

 subcostal and anal veins is not found in any other of our species of 

 ( 'hrysopa. 



Chrysopa oculata Say.- Face pale yellowish ; a reddish spot on each 

 side, a black crescent under each eye 'often connected to the band), a broad 

 blackish band under antennal sockets, emarginate in the middle, sockets above 

 are margined by a narrow blackish line, between an ten me is a reddish spot ex- 

 tending upward in shape of a Y ; vertex with 2 submedian dots (sometimes con- 

 nected to the Y), and a spot each side near eye (sometimes absent). Palpi broadly 

 banded with red-brown ; second joint of antenna? blackish, the first joint some- 

 times marked with red above. Pronotum greenish, with several black spots each 

 side, more or less distinct ; rest of thorax and legs pale greenish, often a dot at 

 tip of each lateral lobe of the metanotum. Abdomen greenish. Wings hyaline, 

 veins green, many of the cross-veinlets marked with black : at least the gradate 

 veinlets and the costals of hind wings usually wholly black; pterostigma often 

 distinct. Length 15-17 mm. 



Very common throughout the Eastern United States and Canada. 

 Variable in size and breadth of wings. Some specimens with broad 

 wings and broadly rounded tips have more black on veinlets, and 

 may be a variety or even distinct species, but I cannot find any dis- 

 tinctive characters. These specimens appear to be most common in 

 early summer. The forms described by Fitch as illepida,fulvibucca 

 and mississippiends appear to me to be only forms of this variable 

 species. The life history has been described by Marlatt. His 

 figure of the larva shows its characteristic markings. The eggs are 

 laid in clusters. Adults are seen from early in July to September, 

 being most common in July. They are chiefly found in tall grass 

 and shrubbery, but sometimes on trees. 



Cliry*opa chloropliana Burm. — This species has the head marked on 

 the same general plan as Ch. oculata, but the mark under each eye is usually short, 

 and the submedian dots on vertex are often indistinct or absent; the palpi less 

 broadly banded with brown. The basal joint of antenna sometimes has a trans- 

 verse red line above, the second joint is blackish. The thorax and abdomen are 

 dark green, the pronotum with a few dark marks each side. The wingsare hya- 

 line, the veins are green, sometimes some of the veinlets, especially the costal 

 series of the hind wing, are marked at their ends with black ; but the gradate 

 series are always green. The pterostigma is commonly very distinct. Length 

 16-17 mm.
