" small and narrow, each rather broader llian long, 4 and 5 broader and 

 longer and as broad as long," as described for the type species, except 

 that in each case here the joints are longer than wide. The antennae of 

 this species appear to agree in general form with those of the type of 

 Rhopoideics.'^ 



Female. — Length, 1.95 mm. Rather long and slender, the body 

 flattened or depressed. 



General colour uniformly brown, but the abdomen somewhat paler, 

 the brown emphasized along the caudal margins of the segments (making 

 at least four transverse brown stripes across the abdomen, which, how- 

 ever, are not conspicuous). Antennœ concolorous; legs somewhat lighter, 

 with some yellow, the tarsi pallid yellowish, the distal tarsal joint clouded. 

 Eyes dark. Wings hyaline, with the exception of a slight cloud of fuscous 

 under the stigmal vein and just out a slight distance from the base, and 

 also sometimes slightly touched with fuscous along the caudal margin 

 irregularly, proximad and along the oblique hairless line at either margin 

 of it. Trochanters and bulbs of the antenna palh'd. 



Mesoscutum and mesoscutellum polygonally sculptured, as if covered 

 with flat scales, both bearing a few, sparse, short setae ; the concave face 

 finely lined with circular lines (concentric about the rather deep and large, 

 crescentic scrobicular cavity in about the centre of the face); carina of 

 vertex present; tarsi 5-jointed, the joints short yet longer than wide; 

 tibial spurs single, the cephalic spur curved and forked at tip; caudal 

 femora somewhat thickened, legs otherwise slender or usual. Fore wings 

 with an oblique, hairless line running |)roximo-caudad from the origin o^ 

 the stigmal vein. j\îandibles short, claw-shaped, acute and edentate at 

 tip. Submarginal vein long and slender, the costal cell rather wide, the 

 marginal vein a mere rounded point where the submarginal touches the 

 cephalic margin, the postmarginal vein absent, the stigmal vein distinct, 

 moderate in length, with a slender neck. Fore wing (including the costal 

 cell) densely, finely ciliated, the blade ample and wide, only about twice 

 longer than broad, the marginal cilia short, becommg noticeable only at 

 apex and disto-caudad, where they are moderately shoit. Caudal wings 

 densely ciliate discally, rather short, Parapsidal furrows absent. Abdomen 



*Dr. L. O. Howard has very kindly examined the type of his Rhopoidetis 

 citrinns for me, and tells me in a letter dated August 8, 191 1, that the antennal 

 club of that species is solid, hence the antennse 8-jointed (excluding- any 

 question of a ring-joint). Ashmead's diagnosis of the genu-s is therefore wrong.
