silky brown, and in this respect the concolorons species recalls 

 Panojjoda, Pleonectyptero,^ and other bright-liued quadrifid 

 genera. The costa is white to the inception of the outer trans- 

 verse line. The innei* line is outwardly rounded, oblique ; 

 approaching the straighter outer line on internal margin. The 

 two lines are dark witli pale rosy shadings. A white transverse 

 streak in the place of the reniform. No other markings on the 

 wing. Tlie hind wings are faintl}' crossed by a diagonal streak. 

 A % specimen has been sent me from Massachusetts for identifi- 

 cation by Mr, Morrison expanding 28 mm. 



Homopyralis, n. g. 



This genus appears intermediate between the genera allied to 

 Homoptera and the Deltoids. The eyes are naked, ocelli very 

 small. The male antennae are lengthily pubescent beneath with a 

 longer bristle on each side of each antenna! joint; in the female 

 the pubescence is absent, and the lateral bristles somewhat shorter. 

 The palpi are long and exceed the front, curved, with elongate 

 third article, closely scaled. The tlioracic squaraation consists of 

 flattened scales with rounded, even apices, those attaclied to the 

 prothorax very broad ; there is a very slight admixture of hair. 

 The size is small, the body slender, the wings broad with 

 Homopteriform ornamentation, the tibiae unarmed. 



Homopyralis tactus, n. s. 



% 9. Dark brown, concolorons Transverse lines black shaded. 

 Orbicular a small black dot; reniform a larger black subluniform 

 spot touched by the double median shade whicli forms the most 

 noticeable feature of the wing, and is repeated on the secondaries 

 where it includes the black discal spot. The t. p. line is geminate, 

 marked on costa, sometimes merely indicated by dotted fragments 

 opposite the cell, where it is somewhat rectangularly exserted, 

 running inwardly below median vein, and approximating to the 

 median shade on internal margin. Costal, pale, ante-apical dots, 

 below which the costal region is darker shaded before the faint 

 subterminal line. A terminal interspaceal series of dots; fringes 

 concolorons. On the hind wings transverse rivulous shades with- 

 out the black median shade; on internal margin these are relieved 

 by a pale yellowisli staining. Beneath pale, with common trans- 

 verse shades, imitating the upper surface, and with a resemblance 

 to the wider surface of the wings in Fseudaglossa.
