172 THK CANADIAN ENTOMOLOGIST. 



gated, terminal joint deeply on dorsal and lateral parts ; head rounded. 

 Color, chestnut brown, as usual coated with a white powder. Puparium 

 a slight lining to the leaves that were fastened together with silk. 



The larva pupated May 17th, and the imago appeared June 20th, 

 giving a pupal period of about a month, which is about the same as the 

 other species that have been bred. One feature of the species is that the 

 larva has no lateral fringe. As given before, the food plant is Honey 

 Locust. 



May 12th, another larva was found that differs from the above descrip- 

 tion only in being darker, and as a natural result the stripes more distinct, 

 the light stripes having an orange tint. After this two more were found, 

 one of which had all the light stripes quite distinctly orange tinted. The 

 head was reddish purple striped with numerous white lines, or rather 

 broken lines. Like the other, the venter had the black only on the joints 

 bearing legs. This one had passed the last moult when found, and pro- 

 duced the imago June 17th, showing that keeping the first in confinement 

 had not materially interfered with its time of pupating or its other changes. 



ON THE CHALCIDEOUS TRIBE CHIROPACHIDES. 



BY WILLIAM H. ASHMEAD, JACKSONVILLE, FLA. 



Below I give an analytical table for recognizing the genera in the tribe 

 Chiropachides Thomson. It will be seen that I have placed in this 

 group the genus Schizonotus Ratzburg, which Dr. Arnold Foerster, in his 

 Hymenopterologische Studien (1856), says is identical with Seladerma 

 Walker, an opinion in which I cannot concur, my type of Schizonotus 

 Siebaldi Ratz. not agreeing at all with Walker's definition ; also the genera 

 Mcsopolobus and Platymesopus Westwood, which were subpressed by 

 Walker and other authorities, and placed in the genus Pteromalus ; they 

 agree in all essential characters with, this group, the anterior femora being 

 very similar to Chiropackys, the type of the tribe. 



Two new genera will be found characterized in this group, the 

 characters of which, as given in the table, being sufficient, it is hoped, to 

 enable them to be easily recognized.
