In view of the above facts we believe that the type should be restricted 

 to the 9 from Arizona in the Neumoegen Collection. At the time 

 we had no material with us that agreed with this type, but if our iden- 

 tification from our notes is correct, the species should be placed next 

 to Racheospila rubrolinearia Pack, to which it bears a close resem- 

 blance. 



Chlorochlamys viridipallens Hist. 



The species was described from Colorado and Arizona ; in the 

 Hulst Collection is a $ type from Colorado, in the Neumoegen 

 Coll. a 9 type from Arizona, this latter being a specimen of volan- 

 taria Pears. The $ type, which should hold the name, is also very 

 close to volantaria but is a little larger and the hind wing seems paler 

 and immaculate as far as can be determined from the poor and faded 

 condition of the specimen ; the fore wings show traces of a post- 

 median line as in volantaria. The hind tibiae of the type are wanting 

 but we think there is no doubt that the species is a Chlorochlamys 

 and eventually when fresh material from Colorado is forthcoming, 

 it may prove identical with volantaria. 



Merochlora graefiaria Hist. (PI. XV, Fig. 17). 



An examination of the structure of the type 9 in the Neumoe- 

 gen Collection has convinced us that this species is identical with that 

 described by Mr. Prout (Gen. Insect. Geom. Hemith. p. 222) as 

 Merochlora entraphes; the type is worn and faded, the green having 

 become a dirty white, but the position of the single white line on the 

 primaries is the same and the structure is identical, the two pairs of 

 spurs on the hind tibiae and the strongly anastomosed vein C on the 

 secondaries being very characteristic. A second 9 type in the Tepper 

 Collection in the Michigan Agricultural College at Lansing, Mich., is 

 in rather better condition and bears out the above reference. We fig- 

 ure a $ from Stockton, Utah. 



OOSPILA LESTERARIA Grossb. 



The type $ in Coll. Barnes has only a single pair of spurs on the 

 hind tibiae and distinct abdominal dorsal tufts and will therefore fall 

 into a group quite distinct from Racheospila in which genus it was 

 placed by the author. Until more material and both sexes are avail- 

 able we place it provisionally in Oospila Warr. as it very evidently 

 belongs in the small group of genera centering around this genus.
