32 ENTOMOLOGICAL SOCIETY 



yellowish on basal third, beyond dull black. Wings hyaline, marked 

 much as in D. venustus; fore wings with an apical black spot, con- 

 taining two subapical pale spots, a large band before it, broken behind, 

 another band before latter and reaching the costa, but much broken 

 up behmd, and before this last band is another, more oblique, not 

 reaching costa, and broken up behind ; on the basal part of wing are 

 many small dots along the veins. Hind wings also marked like D. 

 vcmistus, but the spots are larger and connected through the middle, 

 the pale areas in apical spot are larger, and there is also a small but 

 distinct spot in the middle of basal half of wing; venation brown, 

 partly white as in the other species. 



Expanse 76 mm., width of fore wing 13 mm. 



From Posorja, Ecuador (Campos). 



Eremolecn angustus, n. sp. 



Face yellowish, with a dark-brown interantennal mark, from which 

 a median projection extends down to the clypeus; above antennae pale 

 brown, with a median pale spot just above and between antennse; vertex 

 yellowish brown, with several black spots each side; pronotum brown, 

 with a median yellowish stripe, and a slightly curved yellowish mark 

 on each side; thorax brown, spotted with yellowish, a pair on anterior 

 lobe of both mesothorax and metathorax more prominent than the 

 others ; venter mostly yellow ; abdomen brown, most of the segments 

 with a yellowish mark each side. Legs pale yellowish, tips of all joints 

 black, and the femora and tibiae heavily spotted with the same color, 

 most prominently beneath. Wings hyaline, venation mostly brown, 

 the subcosta, radius, radial sector, and median interruptedly white, 

 some of the cross-veins also white, a short' brown marginal streak on 

 the anal angle of the fore-wings, the pterostigma slightly infuscated. 

 Legs very slender, hind femora longer than mesothorax plus meta- 

 thorax; spurs weak, and barely longer than the first tarsal joint, 

 which is no longer than the next. Wings very narrow, hind ones only 

 about one-half the width of the fore pair, and plainly shorter, fore 

 wings subfalcate at the tips ; radial sector arises beyond fork of the 

 cubitus, but in hind wings plainly before the fork of cubitus, and with 

 but one cross-vein before it. 



Expanse 42 mm., width of fore wing s mm. 



From Santa Elena, Ecuador, It differs from the type of 

 Eremoleon in shorter spurs and narrower wings, but as it 

 agrees in venation I will retain it there, since other species 

 may yet be found intermediate in spur length and width of 

 wings. 



Acanthaclisis assimilis, n. sp. 



Similar in general appearance to A. fallax. The markings of head 

 and pronotum are as in that species ; the palpi, however, are wholly
