known to be capable of. Unfortunately we have no pupae of that 

 species for examination. We shall be glad to learn from any of 

 our lepidopterological readers if they are familiar with this struc- 

 ture in any other pupse, or know of any record of it.— C. V.

Clover Insects. — In his paper upon the insects of the clover 

 plant, read before the N. Y. State Agr. Society, Jan. 19, 1881, 

 Professor J. A. Lintner enumerates but three species of Coleop- 

 tera as being destructive to the plant. 



From personal observation I am now able to more than double 

 the number, the revised list being as follows: 



Hylastes trifolii Muller (larva in roots) . 

 Lan-uria mozardi Fabr. (larva in stem). 

 Gnif/urr/iiuns vacuus Say (imago on leaves). 

 Lachnosterna serricornis Lee. (imago on blossoms). 

 Macrobasis unicolor Kirby (imago on leaves). 

 Colaspis brunnea Fab. (imago on leaves). 



■ imago on blossoms). 



The latter four species are my contribution to the list, all old 

 offenders, and well known to the economic entomologist. 



None of these have so far become to any extent destructive, 

 the Colaspis approaching nearest thereto. But as yet clover cul- 

 ture is in its infancy in the West, hence if the acreage were largely 

 multiplied, the results can now be only a matter of supposition.—

Is Cyrtoneura a Parasite or Scavenger ? — Last spring we 

 sent specimens of a Muscid for determination to Mr. R. H. 

 Meade, Bradford, England, and he kindly wrote us as follows re- 

 garding this species which was bred from chrysalides of the Cot- 



" The Dipterous insects which I received yesterday are one male 

 and two females of Cyrtoneura stabulans Fallen. This fly >s 

 common throughout Europe, and also occurs in North America, 

 according to Loew and Walker (see Osten Sacken's Cat. of Dipt, 

 of N. A., edit. 2d, p. 163). The larvae usually feed upon decay- 

 ing vegetable substances, as fungi, etc., but Schiner (Fauna Aus- 

 triaca, Dipt, Vol. 1, p. 597) says, according to Bremi and Hartig, 

 they also live upon the larvse of Lepidoptera and bees. It is a 

 very interesting fact that they also eat the Cotton-worms. Your 

 American specimens seem to be perfectly identical with my Brit- 

 ish ones, but are rather smaller. I may add that the g enus C y r " 

 toneura Macq. belongs to the family of the true Muscidae." ^ 



There can be no doubt that the Cy 

 from pupae of Aletia, but as the usual 

 those of a £ 



scavenger, some doubt has ;
