Host. — Pissodes, species. 



Tijpe.—Csit. No. 14582, U.S.N.M. 



Described from six female and six male specimens selected from a 

 large series under Bureau of Entomology, United States Department 

 of Agriculture, note number, Hopkins U. S. No. 8574, Josef Brunner, 

 collector. 



In some males the rugse between the lateral folds on the propodeum 

 are, except for the median carina, replaced by punctures. 



An examination of the mandibles of a female shows each to have 

 three teeth. 



This species is named in honor of Mr. C G. Thomson, whose excel- 

 lent monograph of the chalcids of Scandavia began a new era in 

 the study of this group. 



SCYMNOPHAGUS SECUNDUS, new species. 



Female. — Length about 1.85 mm. Head and thorax dull pitchy- 

 black, the propodeum more or less greenish, the abdomen distinctly 

 so; antennae brown, the scape lighter, the three ring-joints distinct; 

 pedicel about as long as the first jomt of the funicle; joints of funicle 

 subequal in length; head and thorax with thimblehke punctures, 

 scutellum with a well-marked transveree furrow; propodeum with 

 sculpture similar to that of mesonotum but finer, and laterad of the 

 lateral folds much weaker, this sculpture not extending laterad of 

 the spiracles; propodeum with no median carina; coxes black, femora 

 except tips, brown, rest of legs brownish testaceous. 



Male. — ^Unknown . 



Habitat. — Pahssa, Bukedi, Uganda. 



Type (and two paratypes). — In British Museum (Natural History). 



Paraty pes. —Cat. No. 14584, U.S.N.M. 



Described from specimens with the data reared from an unknown 

 coleopterous larva collected by Mr. G. C. Gowdey, under No. 2171 

 with the date 1. XII, 1910 and the additional note that the larva so 

 greatly resembled a coccid that at first sight it was taken for one. 



This larva was probably a Scymnus or closely aUied coccinellid 

 genus. 



The above-described species greatly resembles S. townsendi Ash- 

 mead, but the more distinctly differentiated fuiTOW of the scutellum 

 and the less distinct sculpture of the propodeum laterad of the lateral 

 folds distinguish the two species. 



CATOLACCUS TOWNSENDI, new species. 



Female. — Length about 4 mm. Very similar in color and general 

 appearance to C. tiunteri, the venation and antennal characters being 

 about the same; sculpture of face medially weaker than in Tiunteri 

 and composed almost entirely of vertical striae instead of reticula-
