given, in comparison with other species, in Psyche, v, 1890, p. 411. 

 The beak structures are also shown. 



The Entomologist of the Dakota Agricultural Experiment Station 

 has reported of the excessive multiplication of the species in the pre- 

 ceding year (1889), in that state, as follows: " It often crowds the upper 

 and under sides of the foliage in such numbers that the leaves become 

 hidden by the living mass. Indeed, sometimes, weight for weight, 

 there is more animal than vegetable substance jiresent." 



In Insect Life, iii, 1891, p. 289-90, Professor C. M. Weed, has 

 described and illustrated the sexed forms of A. brassicce. They had 

 never before been given, although the insect has been known in both 

 Europe and America for more than a century. Careful descriptions 

 of the winged male, the ovijjarous female, and of the egg are contained 

 in the notice. 



Remedies. — This insect can be effectually controlled by spraying 

 with a kerosene emulsion, or with one pound of whale oil soap dis- 

 solved in eight gallons of water. In order to reach the aphids when 

 congregated on the under side of the leaves, it is desirable to use one 

 of the knapsack sprayers furnished with a Vermoral nozzle. 



Other remedies are named in the notice of this insect contained in 

 the Sixth Report on the Insects of New York p. [52] 148. 



? Myrmeleon immaculatus (De Geer). 

 A Strange Habitat for the Larva. 

 An ant-lion, apparently about half-grown, was received June 3d, 

 from Mrs. E. B. Smith, of Coeymans, N. Y., who had found it beneath a 



carpet in her house. It 

 differed so much in its 

 colors and in structural 

 features from the only 

 species with which I am 

 familiar, M. immaculatus, 

 (often observed and col- 

 lected by me beneath 

 the overhanging lime- 

 stone rocks of the Hel- 

 derbergs, and reared in 

 a few instances) that I had no thought of its being, by any possibility, 

 that species. Added to this, when placed upon the table it traveled 

 both forward and backward with almost equal facility, and when 

 laid on sand, it manifested no disposition to run a circular furrow or 

 to construct a pitfall. Its habitat seemed also most remarkable for
