THE CANADIAN ENTOMOLOGIST. 43 



Macrocentus iridescens, n. sp. 



Length .13 of an inch. Head piceous, the mouth parts, including the 

 clypeus, tawny ; antennas rufo-cinereous, the basal joint yellowish. Thorax 

 light rufous, darkest on posterior part, paler beneath ; wings hyaline with 

 strong iridescence, the veins, costa and stigma fuscous ; feet and legs 

 straw color, the last tarsi of bind feet a little darker. Abdomen rather 

 slender, rufo-piceous, under side of middle joints slightly tawny ; ovi- 

 positor not exserted. Under the microscope a fine grayish pubescence is 

 seen on all parts of the insect, sparse on the abdomen and legs, but pro- 

 fuse on the antennse and wings, not interfering with the iridescence on the 

 latter. Pupa with the host. 



Described from 5 males and 7 females reared from two larvae from an 

 elm tree, that were taken to be Engonia subsignaria. 



I wish to acknowledge here my indebtedness to E. T. Cresson, of 

 Philadelphia, for generic determination of these species, and for other 

 valuable information and suggestions. 



ON THE EARLY STAGES OF SOME MOTHS. 



BY D. W. COQUILLETT, WOODSTOCK, ILL. 



In the following descriptions I have made use of certain terms which 

 will need explaining. The subdorsal line is midway between the dorsal 

 line and the spiracles ; the stigmatal line includes the spiracles ; the sub- 

 dorsal space lies between the dorsal and subdorsal lines ; the stigmatal 

 space is between the subdorsal line and the spiracles. 



The moths of the following larvae were determined for me by Mr. A. 

 R. Grote. 



The first larva described below is provided with only 14 legs; all of 

 the others have 16 legs. 



Hypena scabra, Fabricius. — Body green ; a dark green dorsal line, 

 faintly edged with white ; a white subdorsal and stigmatal line ; venter 

 pale green ; head smooth, green ; length 1 inch. Feeds on clover ; July 

 1 to September 10. Enters the earth to pupate.
