along the outer margin nearest the apex, where it is reddish 

 brown. The underside of both wings bright orange-red, 

 clouded with brown along the outer margins, both wings 

 crossed beyond the middle by two narrow brown lines : pri- 

 maries with a dark brown line extending from the apex to the 

 middle of the outer line, crossing the wing. The upperside 

 of the head, thorax, and the abdomen dark green, the tegulaa 

 tipped with brown ; the abdomen banded with black and with 

 black and yellow spots at the sides and several patches of 

 bluish-grey scales down the middle. The underside of the 

 head, thorax, and abdomen bright orange-red ; the antennas 

 and legs dark brown. Expanse 5 inches. 



Hob. Panama, Chiriqui {Ribbe, type mus. Staudinger) ; 

 Peru (mus. Druce). 



This very fine insect is allied to Clam's achemenides, Cram., 

 specimens of which are before me from Colombia. Walker's 

 Oryba robusta is without doubt conspecific with C. ache- 

 menides and should now be placed in the genus Oryba. A 

 fine specimen of Oryba imperialis is in the Oxford Museum 

 from an unknown locality. 



Fam. Arctiidse. 



Halisidota, Hiibn. 



Halisidota labaca, sp. n. 



Primaries pale brownish yellow, with a small orange- 

 coloured spot close to the base, three large spots along the 

 costal margin, a large elongated patch on the outer margin, 

 and two rather broad streaks on the inner margin partly 

 crossing the wing towards the middle, all pale brown : secon- 

 daries pale yellowish white, partly hyaline near the base. 

 The underside of the primaries as above, but with all the 

 markings more indistinct. The head and thorax the same 

 colour as the primaries ; the abdomen above orange, the anus 

 and the underside whitish ; the legs and antennas orange- 

 brown. Expanse 2g- inches. 



Hab. Mexico, State of Jalisco (Richardson) . 



A very distinct species, but nearest H. cinctipes, Grote. 



EUHALISIDOTA, Grote. 



Euhalisidota agelia, sp. n. 



Primaries and secondaries uniformly greyish hyaline white ; 

 primaries crossed by three very faint yellowish-brown lines. 

 The head, thorax, and abdomen yellowish white ; antennas
