IGG Annals Euiomological Sofiefy of America [Vol. XII, 



Trimeromicrus maculatiis was originally recorded as a 

 parasite in alfalfa seed-pods infested with Bruchophagus funebris, 

 and subsequently proven by Mr. T. D. Urbahns to be a primary 

 parasite upon that host. The record under Tempe No. 2223 

 is interesting as showing that this species may develop upon 

 parasitic forms of Hymenoptera as well as upon the plant- 

 feeding Bruchophagus Jtmehris. In the case of the record under 

 Tempe No. 2264 it is impossible to say whether the specimens 

 of this species were parasitic upon Bruchophagus, which was 

 shown to be present in the Asphondylia galls, or whether it 

 was actually present in its role of a secondary parasite of 

 Asphondylia. 



Family EULOPHID^. 

 Tetrastichus sobrius, new species. 



Female. Length 1.8 mm. Face reticulately shagreened, with two 

 longitudinal rows of shallow punctures between the antenna and eye- 

 margin; antennal pedicel slightly shorter than the first funicle joint; 

 first funicle joint the longest, joint two very slightly longer than three, 

 joint three one and one-half times as long as broad and approximately 

 three-fifths the length of the first; club short, pointed ovate, obscurely 

 three-jointed, the first suture distinct but shallow, the second suture 

 subobsolete; thorax finely lineolated above, the mesoscutum with a 

 distinct complete median groove, scutellum without a median groove, 

 but with the dorso-lateral grooves complete and distinct; propodeum 

 very short, without any carina and very faintly reticulately sculptured, 

 nearly smooth; mesopleura practically smooth, the prepectus distinctly 

 shagreened; basal joint of hind tarsi a little shorter or no longer than 

 the second joint; submarginal vein of the forewing with at least four or 

 five bristles above; abdomen about one and two-thirds times as long as 

 head and thorax, as broad as the thorax and pointed at apex, the tergites 

 very faintly sculptured. Head, thorax, abdomen, and all femora 

 brownish-black; flagellum brownish; scape, pedicel, all tibiae and tarsi 

 pale testaceous; an obscure transverse spot in front of the anterior 

 ocellus, also, pale; metanotum medially, more or less testaceous; wings 

 hyaline, the venation testaceous. 



Male. Length 1.3 mm. Scape of antenna a little thicker than the 

 pedicel and about twice as long; pedicel conical, a little longer than 

 thick; ring- joints very small, the number not discernible; funicle four- 

 jointed, the first joint as broad as long, somewhat shorter and broader 

 than the pedicel, second about one and two-thirds the length of the 

 first; third and fourth joints equal and each a little longer than the 

 second; club plainly three-jointed, about as long as the two preceding 

 funicle joints combined, the apical joint produced at apex into a sharp 

 point; each of the four funicle joints with a half-whorl of hairs above
