Body small, slender ; fore wings strongly hooked ; hind wings tailed. 



AnteuJicE short, very slender, with a very slender but distinct club. 

 Thorax small, oval. 



Fore Wings large, triangular, strongly falcate at the tij). Fore margin very much arched ; apex acutely 

 angulated. Apical margin deeply emarginate ; hinder angle rounded, especially iu the male. Inner margin 

 nearly straight, except towards the extremity, which is rounded. Costal vein extending to the costa, a little 

 distance beyond the extremity of the discoidal cell. Postcostal vein with its first two branches arising beyond 

 the extremity of the discoidal cell, short ; third branch arising at some distance beyond, short ; fourth branch 

 extremely short and oblique ; terminal portion of the vein united to the costa at some distance preceding the 

 tip of the wing. Upper disco-cellular vein very short but distinct and transverse, ainsing from the postcostal 

 at about three fifths of the length of the wing : middle and lower disco-cellular forming a rather curved line, 

 the two being nearly equal in length, closing the discoidal cell by a transverse slightly concave line ; uniting 

 Avitli the third branch of the median vein at some distance from its origin, at a point where it is strongly 

 angulated, this third branch being straight beyond the place of junction. Postmedian vein curved upwards 

 at its extremity in the male, following the outline of the wing in that part. 



Uiiul Wings large, broadly ovate, angulated at the anal angle, and with the middle of the outer margin produced 

 into a tail at the extremity of the third branch of the median vein ; the tail being directed outwards more 

 obliquely than represented in our Plate LXV. fig. 1. The costal margin is nearly straight, except at the 

 base; the outer angle rounded. The anal margin deeply grooved. The precostal vein strong, directed 

 forwards, with the tip bent towards the body. The costal vein running very close to the costa, nearly to its 

 tip. The postcostal vein arising rather beyond the precostal, branching at a considerable distance from its 

 base. The upper disco-cellular slightly curved, forming the base of the discoidal vein ; the outer disco-cellular 

 vein more oblique, nearly straight, and uniting with the third branch of the median vein at a smaller distance 

 from its base than exists between the origin of the first and second branches of the median vein. The sub- 

 median vein extends to the extremity of the anal angle. 



Four Hind Legs rather short, slender, and scarcely spined on the under side of the tibia. The tarsi more 

 regularly sj^ined. 

 Abdomen small, slender. 



Caterpillar long, subcylindrical, slightly thickest in the middle of the body, naked, free from warts or 

 tubercles ; the head oval ; the abdomen terminated by two setose filaments nearly half as long as the whole 

 body, gradually attenuated to the tip. 



Chrysalis oval; the head apparently slightly bifid ; the case of the metathorax gibbose, and the extremity 

 of the body incurved. 



I regret not being able to give more precise and detailed generic characters of the curious insect which is the type of this genus. 

 Our figure represents the male, and will give a general idea of its form, except tliat the tails are directed outwards more in a line with 

 the hind margin of the wing, extending from the anal angle to the tails. At first sight this genus niiglit be considered as very closely 

 allied to Protogonius and Hypna ( PI. XLIX.) ; but the elongated discoidal cell of the fore wings, extending, as will be seen in our figure, 

 to the middle of the broad I'ulvous bar, as well as the general arrangement of the veins of the wings (independent of the peculiar 

 markings of the under siile), at once removes this insect from the vicinity of those genera. The wings, on the under side, are a pale brownish
