 with wings,

Of the habits of this abundant and" widely spread species we know little. Capt* Slater 

 remarks " tolerably plentiful at Dacca, 1844. Flies quietly, and is easily captured. I used to 

 find one or two almost invariably near a deep pool of stagnant water overlinng with bamboo, 

 jungle, &c."f 



A variety J of this species is found in the Nicobar and Andaman Islands, and another 

 closely allied but darker form is found in Ceylon. § 



Genus CIRBOCHROA. 



Cirrochroa, Doubleday, Gen. Diurn. Lep. p. 157 (1848) ; Moore, Lep. CeyL i. p. 62 (18B1). 



Anterior wings subtriangular, either somewhat short and ample or apically prolonged ; costal margin 

 arched and convex, the apes rounded and in some species falcate, the outer margin more or less concave 

 and waved, the inner margin moderately concavely sinuate. Costal nervure extending to about half the 

 length of the costal margin ; fkat subcostal nervule emitted at some little distance before the end of 

 the cell, second at almost extremity of cell, third at a short distance before the bifurcation of the fourth 

 and fifth., the fourth prominently bent and undulated. I>iseo-cellular nervules obliquely bent inwardly, the 

 middle concave and about half the length of the lower; first and second median nervules with an 

 apparently common origin a little beyond the base of the lower disco- cellular. Posterior wings ovate and 

 elongate; eoatal margin moderately convex, the miU'r mui-gin strongly waved; abdominal margin straight 

 to apex of internal nervure and then concavely excavated to anal angle. Costal nervure reaching apex of 

 wing; first subcostal nervule emitted opposite the base of third median nervule; lower disco-cellular 

 nervule obsolete, leaving the cell entirely open ; internal nervure strongly curved at base and slightly 

 at apex. Body somewhat slender ; palpi reaching the upper margin of the head, Ihiely pilose, the apex 

 slender and obtusely pointed : antenna: with a slender, long and gradually funned club. 



In the posterior wings of the male there is a longitudinal broad impression between the discoidal and 

 the first median nervules, somewhat concave above and convex beneath* 



In some species, as the Indian ( \ aoris t \] the sexes differ widely in appfuraniro, the IV; male 

 being of a more obscure and duller colour above* This, however, is not the rule with the 

 majority of the species of the genus.

|| Prof. Wentwood (Trans. Ent. Soc. 1880, p. 113, t* 11) lias described and figured two Gynandromorphoua Kpecitnenfl 

 of C. twrix. which exhibit in each specimen (dither partially or completely! the colour markings of both sexes. 



AflProf. Wesiwaod has pointed out, "The term Liynantlroiuorphkm was first applied by M. Lacordaire to supersede 

 in Entomology that of Hermaphroditism." " In insects, gynandromorphooe fttiecuneDE. partaking abnonnally of the characters 

 of both sexes, are generally bilateral ; the bexual distinctive character? (which are for the most part in those instances the 

 Mcondaffy ones) of one W3t being exhibited on oao side of the body uttd its organs, and the peeulhirilies of the opposite sex 

 being seen on the other half of the insect." This is called "complete" gynandromornhism ; bnt other eases occur in which* 

 ■ Whilst the body of the insect appears to bo unisexual, thy purual nexijul divarication is confined entirely to the *rrond*r$ 

 sexual character*." Prof, WVhhvw.nl nb^rvc-* thai "the pidilmr import of this strange modification in a physiological jniinl
