rise gradually one above another, though, measuring from their 

 base to the tip, they are nearly equal in length. Clypeus some- 

 what longer than broad, somewhat cordate ; in front acuminate, 

 and edged with short stiff hairs. 



Thorax : mesothoracic scutellum and metathoracic pra?scutum 

 neither particularly abrupt nor excavated. Upper ivings as long 

 as the entire insect, with the marginal cell extending consider- 

 ably nearer to the apex of the wing than the third submarginal, 

 which is dilated on the outer side at the base ; second submarginal 

 cell contracted towards the marginal, but has a part of the radial 

 nervure common to both. Legs rather long ; posterior pair having 

 the tarsus longer than the tibia, which terminate in two cal- 

 caria, the interior of which is much longer than the other, di- 

 lated and obliquely cut at tip (a structure found in many of the 

 neighbouring genera, so that it must play some important part 

 in the ceconomy of these insects) ; the spurs of the first two pair 

 of tibiae equal in length ; the tip of the posterior femora and the 

 base (at least) of the lengthened first joint of tarsus, have each 

 a brush of short hairs. 



Abdomen rather slender ; the first segment narrowed into a turbi- 

 nate jDedicel, not quite so long as the other segments taken 

 together, at base cylindrical* ; second segment very slightly 

 contracted at base, then suddenly campanulate (or rather acorn- 

 cup-shaped) and much larger than the others which it encloses ; 

 the tips of it are simple f. 



* In Mr. Shuckard's collection, a black Mexican insect, and one at least 

 of St. Fargeau's genera, have this part much depressed. 



■f There exists in the collection of the British Museum, without locality 

 attaclied to it, a somewhat longer-bodied but shorter-winged insect, with the 

 first abdominal segment pedicellate, the second much broader than in My- 

 rapetra, and appearing encircled at the apex by a coronet of short flattened 

 equal processes placed close to each other, somewhat like the peristome of 

 certain mosses ; the second segment nearly conceals the other segments, 

 from one of which, however, the processes may arise. 



The clypeus in this is rather square in front, angulated in tlie middle, and 

 furnished with several short stiff hairs; the sides in front also angulated. 



The mandibles are somewhat elongate, rather thicker at base than the 

 tip, which ends obliquely and appears to have four close teeth (the inner in- 

 distinct ?). The metathoracic scutellum is longitudinally hollowed in the 

 middle ; the anterior wings have the second suhmarginal cell somewhat 

 lozenge-shaped, and slightly hut distinctly petiolate towards the radial ner- 

 vure ; the third cubital is dilated exteriorly at base. J propose to name 

 this subgenus Anthreneida. 



The only species {A. coronata, n. sp.) I have seen, is the one alluded to 

 above, which has the thorax and abdomen deeply punctured ; it is brownish 

 black, with the first abdominal segment rufous ; clypeus in front yellowish, 

 rather smooth. Over the whole of the insect there is more or less of a brown- 

 ish silky pubescence, more especially on the second large, campanulate, ab- 

 dominal segment ; the wings are clear, except the marginal cell, wliich is 

 brown (the brown extends somewhat over the radial nervure on the outside 

 of third submarginal cell), and a narrow line of the same colour below costal 

 nerve widening towards the stigma ; the flattened abdominal processes are 

 yellowish and margined at the extremity.
