short veinlets along the hind margin arc mostly dark. Wings broad; 

 the forewings hardly falcate at tip; the hind pair but little longer than 

 front wings, falcate at tip, but not as strongly so as in C. mirabilis; 

 about four erossveins before the radial sector in the forewings, about 

 eight branches to radial sector in each wing, the sixth branch is soon 

 forked, otherwise venation much as in other species. 

 Expanse 68 mm. 



From Kongo, West Africa, in coll. Banks. 

 Echthromyrmex MeLach. 

 (Palparidius Peringuey.) 



Antenna? hardly diameter of basal joint apart, not very long; 

 legs rather short, basal joint short, apical as long as others 

 together, the spurs nearly as long as two joints, tibiae shorter 

 than femora; pronotum very short; male appendages extremely 

 long. Wings rather broad; costals simple, one erossvein before 

 radial sector in the hind wing, in forewings the first branch of 

 radial sector arises barely before the cubital fork. In hind wing 

 the cubital bends upward and then downward to the anasto- 

 mosis with the median, the anal parallels it so that the cubital 

 fork is indistinct. 



Type — E. platypterus MeLach. 



I have not seen the type species, and the above description 

 is taken from the species described below which I believe is 

 congeneric; at least it agrees with McLachlan's description, and 

 is remarkable in having, as he said, the "postcosta simple" 

 (= cubitus); in this feature it is related to the South American 

 genus Di mares, and the markings of the wings are also similar 

 to that genus. The genus, Palparidius, recently described by 

 Peringuey is the same, without doubt ; it has no very close 

 relation to Palpares. 



Echthromyrmex fascipennis n. sp. 



Face yellowish; a transverse brown mark on face, a large brown 

 interantennal mark slightly pointed below on the middle, and extending 

 up in front of the vertex, which is bilobed; four pale brown marks on 

 vertex in a curved row; antennae dark brown; pronotum very short, 

 nearly twice as broad behind as long, much narrowed in front, pale, 

 with a median black stripe, and an oblique lateral one each side, many 

 minute black points at base of bristles; rest of thorax black, a broad 

 pale stripe over middle behind the anterior lobe, and including a median 

 dark stripe; thorax at base of wings pale; abdomen dark, a pale median 

 and a lower lateral stripe, all very narrow toward tip; appendages yel- 

 lowish, blackish near base below; legs yellowish, rather short and heavy, 

 not very hairy, basal tarsal joint barely longer than the second, apical 

 as long as others together, spurs straight, nearly as long as two joints.
