 red dorsally on segments 3 to middle. Head small, triangular, pale brown, 

 mottled with darker brown. P. T. shield same, with large dark brown 

 patches on either side of dorsal line, on posterior edge, extending down to 

 spiracles and forming a distinct collar. Dorsal tubercles on metathoracic 

 segment on large brown plates. Lateral plates on segments 4, 5, and 6

Pyrausta signatalis Walher'i 



One specimen, Valley, June 26. All other specimens I have seen of 

 Walker's species are a uniform shade of pink. This specimen is heavily 

 shaded with reddish brown, with a broad ciliate ochreous band; the white 

 transverse lines are, however, exactly like typical examples. 



Acrobasis caryivorella Ragonof. 



Four specimens bred from larva? in cases between the leaves of alder; 

 one received May 18 had already pupated; others received June 8, pupated 

 a few days later. Moths issued June 22 to 29. Larva leathery, dark gray 

 or greenish black. Head reddish-brown, P. T. shield ochreous brown, 

 both head and shield very rough, their surface seeming to be covered with 

 minute globules; on mesothoracic segment tubercle ib is on a large black 

 and red chitinous plate. Larval case of grains of black trass and silk, 

 serpentine in .'hape when of small diameter, but becoming straighter or 

 cornucopia like when the larva is mature. Cocoon formed by spinning 

 a rounded cover over the end of the case, or sometimes between two leaves. 

 A large Hymenopterous parasite was bred from one larva. 



Acrobasis kearfottella Dijar. 



One specimen, bred from larva in case between leaves of hickory, received 

 May 28. 



Larva with skin of leathery brown texture. Case of grayish white silk 

 with an occasional grain of grass, somewhat flattened, its small diameter 

 serpentine, enlarging into a chamlier 20 mm. long by 6 mm. wide by 4 mm. 

 thick. Pupa in cocoon spun in the large outer end of the case.
