rather large. Sculpture usual, no especial punctures or setae. A row 

 of faint pimctures across caudal margin of the pronotum. Trochan- 

 ters, mesal margin of axilla narrowly and sometimes the entire face 

 ventrad of antennae and mesad of the genal sulcus, golden yellow. 



From four females reared from a large bud gall on Pinus scopulo- 

 rum at Denver, Colo. (E. Bethel). 



Type. — Cat. No. 19643, U.S.N.M., the above specimens on two tags 

 plus a slide bearing two heads. 



TETRASTICHUS ASPARAGI Crawford. 



Differs from Tetrastiehus hanksi notably in not having a distinct 

 row of pimctures along the lateral margin of the scutum and the 

 pronotum is not punctulate but with only a pair of rows of obscure 

 punctures along the caudal margin. In Hyperteles hlastophagi Ash- 

 mead the scape is pale, the body black, the propodeum with a median 

 carina only. Tetrastiehus acutus Ashmead is more slender, the tibiae 

 and the venation pale, the body black or nearly ; so also Tetrastichodes 

 tibialis Ashmead. Tetrastiehus microrhopalae Ashmead is smaller 

 and has pale venation, the tibiae are pallid and there is no lateral 

 carina on the propodeum; from rapo Walker (Crawford) in having 

 funicle 1 longer than wide, not nearly subquadrate and there is a 

 lateral carina on the propodeum. T. rosae Ashmead has the scape 

 mostly pale. From hruchophagi Gahan in the punctate vertex, the 

 dark venation, the reddish tibiae; from scolyti Ashmead not very 

 much but the abdomen is shorter, the venation black, the lateral carina 

 of the propodeum different (or rather there are two of them) ; the 

 one in scolyti forks distad and the spiracle is long-elliptical or like a 

 slit and just mesad of the base of the carina ; in this species the spira- 

 cle is round and of moderate size. The first lateral carina of propo- 

 deum is obliqued a little meso-caudad, the second somewhat as in 

 scolyti. Types seen.

EPITETRASTICHUS PUNCTATIFRONS, new species. 



Female. — Length, 2.10 mm. 



Like Tetrastiehus asparagi Crawford but the scape is reddish 

 yellow, the venation yellow, the first two pairs of tibiae are infus- 

 cated along proximal two thirds or more, there is a very distinct row 

 of punctures along the lateral margin of scutum, the vertex and upper 

 face are much more densely punctuate, the punctures nearly confluent 

 (scattered on lower face, the facial impression finely scaly) and the 

 pronotum has a slightly rougher sculpture, also the propodeum is 

 punctate, its lateral carina represented by a flat, smooth spiracular 

 "sulcus" whose sides are very finely carinated but the mesal side so 

 only at base and the carina of the lateral side turns in mesad at the
