Genus VI. LOXURA. 



LoxuRA Horsfield. 

 ]\Iykina p. God'. 

 Marmessus p. Hilbner. 



Body moderately robust, short : wings of a uniform pale colour beneath, destitute of ocelli ; hind wings produced 



into a single very long tail. 

 Head small, short, hairy, with a small transverse tuft behind the eyes. 



Eyes large, naked. 



Antenna; very short, not more than one third of the length of the fore wings, slender, gradually thickened ; 

 forming a very indistinct and elongated club ; the tip acute, not ringed with white. 



Labial Palpi greatly elongated in both sexes, longer in the female, equal to half the length of the antennas, 

 compressed, slender, scaly, slightly obliquely porrected ; the tip not elevated above the middle of the eyes ; the 

 terminal joint nearly horizontal, slightly curved, acute at the tip. 

 Thorax elongate-ovate, clothed with long fine hairs. 



Fore Wings subtrigonate. Costal margin very strongly arched from the base to the tip ; apical angle acute. 

 Apical margin nearly straight ; posterior angle subacute. Inner margin nearly straight. Costal vein reaching 

 to the middle of the costa. Postcostal vein with only three branches ; the first and second arising before the 

 anterior extremity of the discoidal cell ; the postcostal itself slightly angulated at about the same distance 

 bej'ond the second branch as exists between the first and second branches ; the third branch arising con- 

 siderably beyond the middle space between the cell and tlie tip. Upper disco-cellular vein very short, oblique, 

 arising at the angle of the postcostal vein : middle and lower disco-cellular veins very slender, transverse, 

 equal in length, closing the discoidal cell at about the middle of the wing, the lower one uniting with the third 

 branch of the median vein at a moderate distance beyond its origin. 



Loicer Wings elongate-triangular ; the outer margin straight, entire ; the third branch of the median vein 

 extending at its extremity into a very long slender tail ; the tip of the submedian vein extending into a 

 moderately prominent lobe. Costal vein extending to the outer angle. Postcostal vein branching at a 

 moderate distance from the base ; the disco-cellular veins very slender, transverse, forming the short closed 

 discoidal cell. Tlie upper disco-cellular arising at a short distance beyond the branch of the postcostal ; and 

 the lower disco-cellular uniting with the median vein at the origin of the third branch. 



Fore Legs nearly alike in size and general appearance in both sexes, scaly, short, those of the males with the 

 tarsus two thirds of the length of the tibia, exarticulatc, compressed, obtuse at the tip, finely scaly, armed 

 beneath with minute spines, and terminated by a few small curved spines. The tarsus of the female five-jointed, 

 depressed ; the basal joint half the length of the tarsus ; the second, third, and fourth joints very short ; the fifth 

 ovate, terminated by two minute ungues, with very small pulvillus and pseudonychia. 



Four llind Wings short, scaly. Femora hairy beneath, intermediate ones with a lobe beneath near the tip. 

 Tibia of equal length with the femur, with a depression near the base. Tarsus equal to the tibia in length ; 

 basal joint half the length of the tarsus. Femur and tibia of the hind pair shorter than in the middle pair. 

 Tarsus one third longer than the tibia ; basal joint swollen, subovate, nearly equal in length to the entii'e tibia ; 

 terminal joints similar to those of the fore legs of the female, depressed. Ungues, pulvillus, and pseudonychia 

 minute. 

 Abdomen small. 



This genus has been united with tlie following by Godart, Boisduval, and E. Doubleday ; but I agree with Dr. Horsfield in the 

 propriety of its separation from the other Myrinaj. The antennas more evidently incrassated towards the point, with the terminal 

 joints more distinctly bristly, the more elongated palpi, the jirominent eyes, the more elongated hind wings extending into a single long 

 tail, and the rather more elongated fore legs, are the chief characters upon which Dr. Horsfield relies. In addition to these characters, 

 I find the logs in the typical species much more slender and shorter than in the types of Wyriua ; the basal joint of the hind tarsus 

 greatly swollen in both sexes; the lower disco-cellular vein of the hind wings uniting with the median vein exactly at the origin of the 

 third branch. Another subsidiary character consists in the almost complete identity in the general appearance and colours of the two 

 sexes. In this latter respect it affords a striking difference from the species of Ph»dia and Myrina; agreeing, however, with the former 

 in the general uniformity of its colours.
