Compared with types of the named species. 

 I^ypes — Catalogue No. 19921, U.S N.M., two males, four 

 females on two tags, a female head and hind leg on a slide. 



Hyssopus, n. gen. of Ophclinini. 



Female — Agrees with the description of Dichatomiis Foerster, 

 but the scutellum bears the lateral grooves which join around the 

 apex, and there is but one very short ring-joint (but the base of 

 funicle 1 is rimmed like a second one). Club without a terminal 

 nipple, distinctly 2-jointed. Propodeum with a distinct median 

 carina and a lateral carina, which runs directly from the spiracle. 

 Mandibles 7-dentate, 6 and 7 small, feebly divided. The large, 

 quadrate pronotum longer than the scutum. Abdomen subsessile, 

 flattened, a little longer than the thorax. Cephalic tibia without 

 a strigil, the spur short and straight. Marginal vein subequal to 

 the submarginal, the stigmal slender, about a third of the length 

 of the marginal, shorter than the postmarginal. 



Hyssopus thymus, n. sp. (Genotype). 



Female — Length 0.85 mm. 



Very dark, nearly black, the wings hyaline, the thorax scaly, 

 the propodeum glabrous, the trochanters, tips of tibiae broadly, 

 and the tarsi yelIow% the venation dusky yellow. Pedicel a half 

 longer than wide, a half longer than funicle 1, which is a little longer 

 than wide and longest, 2 and 3 wider than long (2 a little the shortest) 

 4 a little wider than long, larger than 3. Club ovate, wider than 

 the funicle, its first joint largest. Marginal fringes of the fore wing 

 a little longer than usual. Propodeum latero-dorsad distinctly 

 pubescent. Tarsal joints not long.

 Antenna? 8-jointed, without ring-joint, the club 2-jointed ending
