Formicaleon brahmanicus n. sp. 



Head pale yellowish, a dark line under each antenna, and a spot above 

 each, a bicurved line across in front of the vertex and a T-shaped mark on 

 each side, and two little spots behind; antennae brownish, annulate with 

 darker brown, palpi pale; pronotum pale, but not clear, a dark stripe 

 along each outer margin from the transverse groove backward, and within 

 is another lateral stripe each side slightly approximating behind; thorax pale, 

 with many dark marks, one round each corner of the middle lobe, large 

 geminate spot above each fore-wing, a streak reaching backward, leaving a 

 very broad pale median area; pleura pale; abdomen pale, with a brown 

 stripe each side, twice indented from above on each segment, segments 

 three and four with a median and an apical spot (latter may be united to the 

 side-stripes), fifth and following segments with the side-stripe broad and 

 connected broadly at tip of segments; last few segments of venter dark; 

 legs pale yellowish, with some black dots at base of the black bristles; mid 

 and apical dark bands on tibiae I and II, tips of tarsal joints one to four 

 black and a preapical band on last joint, this joint being nearly as long as all 

 others together; spurs not much curved and as long as four segments, legs 

 not very slender, femora thickened. Wings hyaline, longitudinal veins in- 

 terrupted with dark spots, very faint on median vein, cross-veins often dark 

 at ends ; stigma very faint, a dark dot on the radius below stigma and one out 

 near tip of wing, a spot between median and cubitus near their ends and one 

 on cubital fork near margin; hind wings with many forks and veins in outer 

 posterior part of wing embrowned, so as to form a dark streak subparallel 

 to the outer fourth of the hind margin. Hind-wings longer than forewings, 

 and a little more slender and very acute at tip, fore-wings also slender, and 

 with acute tips, seven cross-veins in fore-wings before radius, eleven or twelve 

 branches of radial sector, in fore-wings seven cross-veins between a cubi- 

 tal fork and anal, in hind-wing anal ends only a little beyond cubital fork, in 

 fore-wings the vein up from end of anal soon runs back to the margin.

TRICHOPTERA. 



Dinarthrodes niger n. sp. 



Black, with rather reddish brown hair, legs brownish; antennse with tips 

 and base on outer side of joints white, leaving a triangular black portion 

 on each joint; maxillary palpi erect, densely haired, the broad joint masking 

 the face; basal joint of male antenna fully twice as long as vertex, very large, 

 slightly concave beneath, above with two large erect processes; the basal 

 one not as high as the other, concave within and from upper inner angle is 

 a long slender process reaching over to the opposite antenna; second pro- 

 cess rather beyond the middle, subconical. Legs slender, not densely haired, 

 spurs, 2, 4-4. Fore-wings rather slender, apex roundedly truncate, forks
