bodv. The very minute palpi and short rough legs, together with the four-branched postcostal vein of the fore wings, and the 

 presence of a short precostal vein in the hind wings, are further characters of the group. 



In selecting the species of this and the preceding genus for illustration, I was led to believe that the insect represented in Plate 

 LXXVI. f. 7. was a species of Boisduvals genus Pentila ; and as those represented in fig. 5. and 6. of the same plate differed gcneri- 

 cally from the former, I gave them a new generic name, which must be expunged, as I find that the two latter insects are congenerous 

 with Boisduval's type Pentila undularis, and that the former is, in fact, a species of Miletus (Grerydus Boisdnval). The female of 

 P. Abraxas (PI. LXXVII. f 5.) has the wings more suffused with brown than the male. The under side of P. Acra;a (PI. LXXVII. 

 f. 6) is coloured in the same manner as the upper side, except that the black margins of the wings are marked with rows of white 

 spots.

Obs. — TiNGEA TROPiCALis, described by Boisduval in De/egoryue's Voy.en 

 Afrique, ii. p. SSp., a native of Port Natal and Ashanti 

 (an insect which I have not had an opportunity of ex- 

 amining), may possibly be closely allied to Pentila. It 

 is described as resembling Acrsa punctatissinia, a native 

 of Madagascar.

Petavia 



This Javanese insect, referred by Godart to the genus Polyommatus, arranged by Hiibner at the end of the Satyridse, and given by Dr. Horsfield as one of 

 the normal genera of his vermiform stirps of butterflies (Lycsnidic nob.), with the remark that it is nearly related to Hesperia, but not described by the last- 

 named author in the text of his work, belongs to the Heterocera or nocturnal Lepidoptera, proved not only by the structure of the legs, as represented by 

 Dr. Horsfield, but also by the veins of the wings, which I have been enabled to examine through the kindness of Dr. Horsfield in placing in my hands one of 

 his original specimens.

This insect, placed by Boisduval between our genera Lycfena and Miletus, is also one of the Heterocera. The veins of its wings (very inaccurately 

 represented in Boisduval's figure) are arranged almost as in Callidula, and the hind tarsi have two long spurs in the middle.

Represented amongst the diurnal Lepidoptera after the Lycsnida?, also belongs to the Nocturna, forming with two other species Boisduvafs genera Damias 

 i^Voy. Astrolabe, pt. 1. p. 259.); apparently also allied to Callidula, as Boisduv.-il observes that "sans les .mtennes ct les pattes on prendrait les insectes de 

 ce genre pour des Diurnes voisins du Papilio Petavius des aiiteurs."
