openings oblique; petiole shagreened, three to three and one-half 

 times as long as wide, basal lamina narrow, lateral carinae usually 

 wanting, sometimes vaguely indicated near base; gaster slightly 

 longer than metaf emur ; abdominal segments 4 to 7 with a few sparse 

 lateral setae; eighth tergite obscurely shagreened, provided with a 

 few slender setae ; spiracles oval ; cerci obovate, located near posterior 

 margin of ninth tergite; penis valve (fig. 14, I). 



Type locality. — Florida. 



Type. — Holotype, female, British Museum; comparisons made by 

 Dr. Ch. Ferriere. Types for the synonym: torvina Cresson, 1671, 

 U. S. National Museum, and 1780, Academy of Natural Sciences of 

 Philadelphia. 



As can be seen from the host list given below, this species has been 

 reared from a number of diverse Lepidoptera, Coleoptera, and para- 

 sitic Hymenoptera. It has been reared as a primary and secondary 

 parasite. It would seem doubtful that the forms reared from all 

 these hosts should belong to the same species, although they are 

 morphologically identical or the slight differences discernible be- 

 tween some specimens can be shown to intergrade. It has not been 

 possible as yet to rear this parasite through more than one generation, 

 but it may be that more successful biological studies will show that 

 the same forms will oviposit in all these diverse hosts. If such is 

 the case, tTie selection of a host by this species is governed solely by 

 the availability of that host. All the host species for S. side occur 

 in about the same environment. 



Doner " has given a brief life history of this species, under the name 

 Spilochalds tormrKi (Cresson) . He reared it as a rare primary pupal 

 parasite of Coleophora pnmiella.
