\^ol. XXviii] ENTOMOLOGICAL NEWS. 257 



there is a large, yellow stain under distal submarginal and all of the 

 marginal veins, the postmarginal vein is slightly longer than the stig- 

 mal instead of being shorter; it is subequal to the marginal which is 

 somewhat over thrice longer than wide. Types compared. 



Head and thorax finely scaly, the scutum noticeably hairy ; the axillae 

 joined or nearly so. Head a little longer than wide, subtruncate at the 

 mouth, the scrobes short, forming a triangle, the frons not prominent, 

 the face inflexed but not greatly. Mandibular teeth subequal, acute. 

 Ovipositor free, very slightly extruded. Eyes somewhat longer than 

 the cheeks. Flagellum long, filiform-clavate, about twice the length of 

 the club which is but slightly enlarged, its third joint longest, sub- 

 equal to funicle 2. Propodeum glabrous, plane, transverse, shorter at 

 the meson, the spiracle small, oval. 



One female, Glenndale, Maryland. Open woods, by sweep- 

 ing, September, 191 6. 



Type : Catalogue No. 20637, U. S. National Museum, a fe- 

 male on a tag, the head, a hind tibia and a fore wing on a slide. 



BLATTOTETRASTICHUS new genus. 



Based on Entcdon hagoioici Ratzeburg (equals Tcfrasti- 

 chodcs floridanns Ashmead) and differs from Ceratotetrasti- 

 chodcs in bearing but three ring- joints and the antennae are 

 inserted below the middle of the face while the male antennae 

 bear four fimicle, three club and two ring- joints. The metal- 

 lic coloration, white legs (except the first pair of coxae), pale 

 yellow scape, pedicel, ring-joints and abdominal petiole and the 

 fact that the scutum bears scattered, setigerous punctures and 

 the pedicel and funicle i are elongate, are characters which 

 make the species easy to be known. The specimens of it seen 

 by me were from the eggs of domestic cockroaches from 

 Louisiana and agree with Ratzeburg's short description : "Die 

 Vorderhiiften grossentheils dunkel ;" otherwise as in Eulophns 

 xanthopus Nees (as to coloration). 



Genotype : B. hagenozvi Ratz.. a cosmopolitan species. 



The following new species was labelled as the above species, 

 in the collections of the U. S. National Museum : 



Epomphaloides ischnopterae new species. 



2. A little less stout than hagcnorvi and black, the legs white, the 

 funicle joints somewhat shorter; scutum with sparse punctures along 

 its lateral margin only; mandibles with but two teeth, 2 broad and 

 truncate at apex ; male scape much shorter, much dilated, funicle I 

 shorter than the other funicle joints. Otherwise the same.
