mens in tin- museum, belongs to a different genus, with a 

 very long tongue, closely related to M c/i/mna. It differs from 

 Mclitoina in the long six-jointed maxillary palpi, lacking con- 

 spicuous lateral brush of hairs, and in the venation of hind 

 wing, the separation of discoidal and cubital ncrvuiv> being 

 about equally distant from transversomedial and transverse- 

 cubital. True Ancylosccles, including urslnus, armatns and 

 turmalls, is a distinct genus, peculiar to the neotropical -region, 

 but widely spread therein. Haliday's type may be redescribed 

 as follows : 



Ancylosceles ursinus Haliday. 



$ . Length about 9 mm., anterior wing 8.3 mm. ; head and thorax 

 with rather short ferruginous hair; abdomen densely covered with ap- 

 pressed velvet-like ferruginous hair ; legs with ferruginous hair ; base 

 of mandibles yellow, with a black spot on upper part of yellow area; 

 labrum yellow ; clypeus yellow, with two large black triangles above, 

 joined in the middle line, so that the lower margin of the black is 

 W-like; apical part of scape red in front; flagellum dark reddish, not 

 very long; tongue broadened and fan-like at tip; hind femora very 

 greatly swollen, oval, with the inner face flattened and ferruginous ; 

 hind tibiae much swollen, with an angle or low tooth on outer side 

 beneath, not far from apex ; hind basitarsi pale yellowish, somewhat 

 swollen, but otherwise simple; wings dusky; transversomedial of hind 

 wing a little oblique, a little (but distinctly) nearer to separation of 

 discoidal and cubital nervures than is transversocubital ; third submar- 

 ginal of anterior wing broad above, its breadth on marginal more than 

 half as great as its lower side; first recurrent nervure joining second 

 submarginal cell at about the beginning of its last third ; stigma well 

 developed ; apex of abdomen not bidentate. 



Ancylosccles turmoils (Yach.) is closely allied to A. ursinus, 

 but smaller, with no black spot on yellow of mandibles. The 

 clypeus is more reddish, but the two black triangles arc present. 

 and the insect has the same red pubescence. Tn the hind 

 wing the separation of the discoidal and cubital nervures is a 

 little nearer transversocubital than transversomedial. The hind 

 legs are of the same type, but the hind basitarsi have a tooth- 

 like angulation on the anterior side, a structure much more 

 developed (thorn-like) in A. armatus. 



Diadnsin is a perfectly distinct genus, closely related to 

 I'tHothri.r, but having a pulvilhi<. I'tilofliri.r rlparla Ducke 

 b.-i ;i puKillus and long third sumarginal cell, and it is to 

 called Dladasia riparia.
