Elachistus coxalis Howard 



One pair, San Mateo County, California, the male; and Laguna 

 Beach, Southern California, the female (C. F. Baker). 



The following species is an Eudecatoma (there being no distinct 

 substigmal spot but only a very minute one) but for the present 

 I include this segregate within the older one. 



Decatoma subimmaculata n. sp. 



Female: Length, 2.00 mm. Of the usual habitus and sculpture, 

 the punctation not coarse. 



Honey yellow, the wings hyaline, the following black markings: 

 Ocellar dots obscurely, upper margin of occiput (a crescent), 

 median channel nearly to apex and cephalic margin of the propo- 

 deum (except laterad) ; abdominal petiole and the median line of 

 abdomen dorsad narrowly, from just before apex of segment 2 

 nearly to the apex of segment 4. Abdomen compressed, segments 

 2, 4 and 5 subequal, longest, the abdomen glabrous, its petiole about 

 twice longer than wide. Propodeum openly rugoso-punctate, the 

 median channel single, distinct, no median basin. Pedicel black 

 above, nearly twice longer than wide, a little longer than funicle 1, 

 the other four funicle joints subequal, subquadrate. Club 2-jointed, 

 the first joint shortest. 



One female, Claremont, California (C. F. Baker) ; on oak. 



Type: Catalogue No. 20400, U. S. National Museum, the 

 female on a tag, the antennae and a caudal leg on a slide. 



Differs from catesbaei Ashmead (types compared), in being 

 larger, the median channel of the propodeum is distinct for its whole 

 length and does not consist principally of two large foreae, the cross- 

 carina passing profimad of it has an area on each side of the meson 

 which runs at first nearly parallel to the channel (the forking) but 

 in the Florida species, this carina continues more or less parallel 

 with the cephalic margin of the propodeum. 



Scutellista cyanea Mots 

 One female, Claremont, California (C. F. Baker). 



Cleonymus calif ornicus n. sp. 

 Female: Length, 4.00 mm.
