IN CERTAIN LEPIDOPTERA. 333 



transparent, and of extreme tenuity. The penis is of unusual length and slenderness, 

 resembling a very fine copper wire. 



In 0. Statira, the valve is still more remarkable. Here the pear-shape is lost ; for the 

 extremity runs into a long, sharp, curved spine, and the dorsal shoulder has two wide 

 semicircular excavations, on the eminence between which stands, attached by one angle, 

 a triangular plate, the outer edge of which is notched into a dozen saw-teetb. This, I 

 presume, is a harpe, and replaces the pincushion of G.Eubule. The tegumen projects 

 in along sballow channel, which can hardly be called an uncus, though it replaces one ; 

 beneath this is seen a minute scaphium, which simulates the form of an uncus. Tbc 

 penis is long, arching, and wiry, much as in Eitb 



Goneptenjx. Tbe valve of G. Ehamni is small, but well made, rotundo-triaugular, 

 oblique, terminating in three horny points, of which the dorsal one is a rather long, 

 slender, acute spine, which leans across the valve, so as to project beyond the ventral 

 edge. This represents, but is not, a proper harpe. There is a small well-formed uncus, 

 which, strangely, is translucent white, and a large penis, but no trace of a scaphium. 



In the fine G. Leachktna of Brazil the valve is much like this, with very wide fringes 

 of yellow hair-scales. The terminal point is long, slender, upcurved ; and the two dorsal 

 points both belong to that which supplants a harpe. There is a proper uncus, small, 

 hooked, and a scaphium, very minute but apparently normal, beneath it. The penis, in 

 this species, is long and prominent ; its terminal expansion takes the singular form 

 of two triangular lobes, looking exactly like the anal and dorsal fins of a mullet. 



G. Clorinde, of Paraguay, has a similar valve. The uncus is a large blunt hook, 

 polished white, like ivory, which bears beneath it a perfect little scaphium, in which, 

 I believe, I can trace the " double teeth," though excessively minute. 



Hebomoia. H. Glaucippe is well armed. The valve is an oblique trapezoid, ending 

 in two stiff slender spines ; the ventral margin semioval in outline, furnished with a 

 ' broad white fringe. Its long very slender harpe runs transversely across the base, 

 ! which throws up an elevated tooth at the dorsal end, and terminates ventrally in a more 

 or less produced hook. It is quite papilionine in aspect, though no part, I think, is 

 serrated. There is a long black uncus nearly horizontal, but bent down at the point. 

 This is furnished with an ample scaphium of a polished brown hue, quite dark in parts . 

 it has a long keel, projecting beyond the hook of the uncus, with long and deep rami, 

 and a stout, horizontal, decurved black tooth on each side. 



Tei'ias. The valve of T. Ilecabe is semicircular, running off to a tooth-like point at 

 the vertex. The concavity is deep, almost hemispheric ; and the margins are very broadly 

 turned over, their inward edges elaborately furnished with spines, long, slender, sharp, 

 arching over the cavity. On the dorsal side of the terminal tooth rise two of these spines, 

 and a third on the ventral side, while the ventral point of the basal side runs off into a 



I stout and sharp hooked point. There seems to be no harpe. 

 The uncus may easily escape recognition. Not only is it exceedingly minute, but it 

 seems to be replaced by a projection with two points, the upper curved downward, the 

 lower, longer, curved upward; but the former is the uucus, the latter its scaphium.
