On Certain Grass-Kating Insects. 67 



August, it is probable that the larvae hibernate when partially- 

 grown and complete their growth in the spring. 



Later, in the jar containing specimens collected at various ages 

 from the lawn. Miss Murtfeldt " found the remains of two or three 

 hymenopterous parasites and four cocoons of the characteristic 

 form, color and structure of Meteorus, closely resembling those of. 

 M. hyphantrice.'' 



Egg. — Obconical 0.5 mm. long, beautifully sculptured under the lens, 

 witli longitudinal ridges and finer cross lines, giving it a checkered appear- 

 ance. Color, bright salmon pink. 



Larva. — At first of a dingy cream white, minutely speckled with brown, 

 with brown head. 



At maturity 15 mm. in length, by 2 mm. in diameter, subcylindrical, 

 slightly larger across thoracic segments. Color yellowish or greenish white, 

 with dull green medio-dorsal stripe. The surface is much roughened with 

 impressed lines, with conspicuous, raised corneous plates, from each of which 

 rises a long, coarse, tapering j^ellow golden hair. Head with protruding 

 lobes and rugose surface and of a dull whity brown color. Cervical shield 

 inconspicuous, darker than the head. 



(These descriptions of the ^%,^, and larvae are quoted from Miss Murdfeldt's 

 account.) 



8. The Rustic Crambus. 



Cranibus ruricolellus. 



PLATES II., VI., XII., XIII., Fig. 8. 



In 1892, this species was very abundant in Ithaca, N. Y. , flying 

 with, and to the casual observer, appearing the same as the Vaga- 

 bond Crambus. The two species are very similar, especially when 

 the specimens are somewhat rubbed. The Rustic Crambus has 

 two irregular oblique rufous markings on the fore wing, while the 

 Vagabond Crambus has no design upon the fore wings. This species 

 is most abundant around damp places and near forests. The 

 moths fly mostly on the early evening, though in dark or shady 

 places they are quite abundant in the afternoon. At times they 

 emerged in swarms, so one sweep of the net captured three or 

 four individuals. The period of flight is limited mostly to the 

 month of August. They are not attracted to lights in large 

 numbers.
