Arhopala gunongeksis, n. sp. 



S . Upper-side : both wings azure blue, purplish in side lights ; primaries with 

 the eosta of medium width, black, increasing towards the apex ; outer margins very 

 broadly black, also increasing towards the apex ; secondaries with very broad blackish 

 margins all round ; abdominal fold grey. Under-side : both wings pale brown with 

 a tinge of olive, with darker spots palely encircled ; the primaries with tliree slightly 

 increasing cell spots, all small, below the third a smaller one in the lower median 

 angle, and a trace of anothei* below the second ; transverse band composed of five 

 indistinct spots, the first three very oblique outwardly, the fourth and fifth below 

 each other and shifted inwards ; submarginal row indistinct ; submedian area paler ; 

 secondaries with four small basal spots below each other, the third shifted slightly 

 outwards, followed by four larger spots below each other with an inward inclination, 

 the fourth of these is really the eighth spot of the catenulated baud, which has 

 become detached therefrom ; cell closed by a subovate spot, below which is a small 

 triangular one ; transverse catenulated band composed of seven spots, the second 

 shifted well outwards, third well out, fourth further out, fifth slightly inwards, sixth 

 very slightly outwards, seventh angular spot well inwards and detached ; submarginal 

 row distinct, three spots of silvery pale blue metallic scaling, beneath which is a 

 trace of two dark spots. Expanse, 36 mm. 



$ . Upper-side : both wings paler than the S > and with narrower margins. 

 Under-side : both wings just like the <J , but greyer. Expanse, 30 mm. 



Sab. : Perak (Grunoug Ijan). 



Tbis species is somewhat near Deva, B.-B., but the blue is by no 

 means so brilliant and lustrous, and the broad margins in the ^ at 

 once differentiate it ; it is one of the rare instances where both sexes 

 have nearly the same extent of blue.

DYSCRITINA LONGISETOSA, Westw., IS A FORFICULID LAEVA. 

 BY E. EENEST GREEN, F.E.S. 



'Tou will be pleased to hear that I have at length completed the 



history of Dyscritina. After keeping two specimens for a long time 



in captivity they rewarded my patience by developing into very 



ordinary -looking earwigs, with well -developed wings and normal 



forceps, and I have since caught a specimen on the wing, attracted by 



my evening lamp. Before the final change — at the penultimate 



ecdysis — -the caudal appendages were abruptly abbreviated, nothing 



but the long basal joint being left ; but this basal joint retained 



its previous character, and had no resemblance to the forceps of the 



perfect insect. 



I am preparing a paper for the next Meeting of the Entomological 



Society, in which I shall give an account of the transformations of 



this curious insect.
