200 ENTOMOLOGICAL NEWS. [May, '07 



In Proc. Ent. Soc. Phil. 3 : 247, 1864, Walsh makes the follow- 

 ing- observation : "I may add here, that as I have recently cap- 

 tured 17 $ $ of A path us citrimis Smith in company with 4 

 % 9 of A. laboriosns Fabr., and as the 3 of the former and 

 the $ of the latter species appear to be unknown, I incline to 

 believe them to be the sexes of one and the same species." The 

 male resembles Bomb us pcrplc.nts, and was so determined for 

 me some years ago by an eminent entomologist ; it is common 

 in this locality on Epilobium angnstifoliiiiu from July 2Oth to 

 August 1 8th. 



Psithyrus contiginis Cr. differs from the male of P. labo- 

 riosns only in having the first two instead of the first three seg- 

 ments lemon-yellow. In 1887 (Syn. Hym. N. Am. p. 307), 

 Cresson considered it as only a variety of P. citrimts. After a 

 careful examination of a rather large series of the males of 

 P. laboriosns I find that the third segment may be entirely 

 black, partially black, or that the yellow pubescence may be 

 mixed with black. P. contigitns is doubtless only an instance 

 where the yellow fails entirely; it has been taken July 3Oth on 



Cardnns odoratus. 



CERATINIDAE. 

 Geratina dupla Say. 



1837, Ccratina dupla Say, 9 < Bost. Jour. Nat. Hist.. I. 387. 

 1864, Ccratina dupla Cr., ?, <$, Proc. Ent. Soc. Phil., 2, 389. 



I take this opportunity to place on record the occurrence 

 of C. dnpla in this locality. The female has been taken from 

 July 4th to August 2ist. on the rose, thistle and goldenrod. 

 I have also specimens of both the male and female of this 

 species, and of the male of C. tejoncnsis Cr. from Elkhart, 

 Indiana, collected by R. J. Weith. 



Mclalopha inornata (Neumcegen). Last September Professor V. A. 

 Clark sent me a number of larvae, which had been found defoliating 

 cottonwood (Populus) trees at Prescott, Arizona. The larva" pupated 

 on the way, and I was not able to determine them until recently, when 

 a couple of fine M. inornata emerged. According to Packard's great 

 work on the Notodontidas, the precise locality of this species was un- 

 known, and nothing had been recorded about its transformations.
