APPLE LEAVES CHRYSOPA SPECIES. 85 



sides, and from that pbint a black stroke is sent downwards upon the cheeks, which 

 stroke is margined on its anterior side with tawny red. Palpi black with white rings. 

 A small oval black spot upon each side of the throat. Thorax with a dusky or black • 

 mark each side at its apex and four spots above at the angles of an imaginary square, 

 and behind these a faint yellowish brown spot each side of the middle. Feet pale 

 dull yellowish. Wings pellucid, their tips angular, those of the upper pair very 

 slightly SO; an opake pale greenish jellow stigma; veins pale green; veinlets branch- 

 ing from the rib vein on both sides black at their bases ; two series of veinlets towards 

 the tip of the wings black, some of them sometimes pale green. Lower wings, veinlet« 

 on the outside of the rib-vein and bases of those opposite to them black. Wings ex- 

 pand 1.10. Found the last of June in this State and also in lUinoiB. When captured 

 it emits the disagreeable odor peculiar to several of its kindred species. 



5: (2.) Head" above with black dots but no stripes. A tawny 

 yellow spot on each cheek, commonly with a black line or dot on 

 its posterior edge. , 



6. (17.) More than two dots upon the top of the head. 



7. (12.) Dots six in number, four at the angles of an imaginary 

 square, the anterior two often confluent with the black margin of 

 the antennse sockets, and one each side behind the eye. 



8. (11.) A black dot or streak on the posterior edge of th<i 

 tawny spot on the cheeks. 



9. (10.) Ends of the veinlets black. 



The 0-MARKED GoiDEN-EYE (C. Omikron). This is of a pale green color with a 

 light yellow head and a black mark surrounding the base of each antenna, broader 

 on the under side, and above interrupted with orange red between the two anterior dots 

 on the top of the head, which are commonly confluent more or less with these black 

 rings. This species corresponds with the one last described in all its details, except 

 that in addition to wanting the black stripes on the head, the veinlets branching from 

 the rib- vein on both sides are black at their tips as well as their bases, and the remain- 

 ing transverse veinlets are mostly black at their bases; and instead of a line in the 

 tawny spot upon the cheeks this commonly has only a black dot. A variety occurs 

 in which the tawny reddish spot ou the upper side of the basal joint of the antennsE 

 is wanting. The wings expand from 0.95 to 1.10, the females being slightly larger 

 than the other sex. It is a common species during the month of June, and exhales 

 , the same disagreeable odor as the preceding. 



10. (9.) Ends only of the veinlets on the outer side of the rib 

 vein and bases of those given ofl" from its inner side black, all the 

 others green. 



The Tellow-hbadkd Golden-ete (C. xanthocephala) is distinguished from the 

 foregoing by having the veins and veinlets all green, except those veinlets which
