four-fifths length of metacoxa; gaster slightly shorter tlian meta- 

 femur ; ninth sternite slightly flattened near apex. 



Type locality. — District of Columbia. 



^2/^65.— Leetotype, female, Washington, D. C, 78 "% October 1886; 

 lectoallotype, Washington, D. C, 78 °^, January 25, 1887, both reared 

 from Meteorus hyphaiitriae jDarasitic on Hemerocampa leucostigma: 

 in the collection of the U. S. National Museum. 



In describing his West Indian species Sinicra cressoni^ Howard ^* 

 stated that "it resembles most closely S. irveteori of the writer's 

 manuscript, reared from Meteorus hyphantriae K-iley in the District 

 of Columbia." This is practically a description, but does not, in my 

 opinion, validate the name under the International Code. Opinion 

 No. 52 rendered by the International Commission holds that the 

 designation of a type locality does not validate a name, and the host 

 designated in the above quotation is probably attacked by other 

 members of this genus. In the same year in which this manuscript 

 name was published, Howard treated this species under the name 

 Spilochalcis dehilis (Say) , discussed its biology, and figured the adult. 

 As has been remarked on page 346 above, the identity of Say's species 

 had been fixed by Cresson in 1872 and was a different species from 

 this one. The figure and biological notes published by Howard for 

 his identification of 8. dehilis constitute a valid description for this 

 species; therefore, I have used his manuscript name as a new name 

 for Spilochalcis dehilis Howard, not Say. The most of Howard's 

 material is still in the U. S. National Museiun. 



Hosts. — Casinaria orgyiae (Howard) (Hymenoptera, Ichneu- 

 monidae) ; Meteorus hyphantriae Riley, Meteorus sp., Apcmteles 

 delicatus Howard, Apanteles sp. (Braconidae). 



Distribution. — Connecticut, District of Columbia, Illinois, Louisi- 

 ana, Maryland, New York, North Carolina, Pennsylvania, Tennessee, 

 Texas, Virginia, West Virginia. 



CERATOSMICRA PAYA, new species 



FiGUBEs 9, r; 10, d; 12, I 



This small black species with yellow and red spots is much like 

 Spilochalcis side (Walker) in habitus, but its long slender petiole 

 refers it to this genus. It differs from all other species in this genus 

 by the extremely wide basal lamina of the petiole, and the metacoxa 

 strongly punctured on the ventral side with the outer dorsal surface 

 strongly shagreened; in C. dehilis (Say), which this species most 

 closely resembles, the metacoxa is slender at the apex and lacks 

 strong punctures on the ventral side.
