Mompha circumscriptella Zell. 



This species was described by Zeller from Texas specimens in 

 1873 (Verh. Zool.-bot. Ges. Wien., xxiii, 312, 1873). Chambers (Can. 

 Ent., X, 239, 1878) writes of Texas specimens having been received 

 from Miss Murtfeldt, who informed him that the larvae fed upon 

 the immature seeds of (Enothera and pupated within the capsules. 

 Smith (Ins. N. J.) records it from Anglesea, N. J., August 30, rare, 

 the larva in the seed capsules of evening primrose. 



The species is really not so rare in New Jersey provided one 

 looks for it. We have found it occurring at New Brunswick, Bound 

 Brook and Egg Harbor. The larva lives in the seed capsules, con- 

 fining its feeding to the seeds in a few of the compartments and 

 destroying only from one fourth to one third of the seeds in a single 

 capsule. 



Egg. — Not observed. 



Full Grozvn Larva. — Length 5.7 mm. Width i mm. Subcylin- 

 drical ; whitish; head dark brown; on either side of front of head 

 is a light band, meeting on apex; ocelli lateral near ventral margin 

 of head, seven, arranged in a ring; each segment beginning laterad 

 of the ventral surface bears a row of fine hairs, equidistant but not 

 in a straight line ; on head, first body segment and legs are several 

 fine hairs; in partly grown larvae last body segment shows a dorsal, 

 dark anal plate which is lighter and hardly apparent in older larvse. 



Pupa. — Length 3.8 mm. Width i.i mm. Shape similar to that 

 of other micro-pupae ; reddish-brown with middle portion of abdo- 

 men slightly lighter ; dorsal surface of anal segment bears two mi- 

 nute tubercles. 



Adult. — Mompha circumscriptella. Chambers (Can. Ent., X, 239, 

 1878), in writing of this species, gives the following description and 

 remarks : " I have not seen Prof. Zeller's specimens, but I have 

 received from Miss Murtfeldt specimens which, with the aid of 

 Prof. Zeller's figure and description, I recognize without difficulty 

 as belonging to this species. The thorax, head and palpi are white, 

 except that the basal part of the second joint of the palpi is stained 

 with brownish. The fore wings are of a pale grayish ochreous, with 

 the dorsal margin from the base nearly to the middle snowy white, 

 the white crossing the fold at the base, and further back again 

 crossing the fold and reaching almost to the costal margin ; it is
