882 HYALOTHYRUS; MIONECTES; GRYNOPSIS. By Dr. M. Dkatot. 



lacydus. L. lacydus Drc. (= pamphygargyra Mob., aon Plotz) is a uni-colonred blackish-brown insect with 



ochreous-yellow palpi. Nicaragua, Panama to Para. 



crinisius. L. critlisius CV. (171 e) is above blackish-brown, in the basal half haired ochreous-yeUow, at the body 



olive-green; on the forewing in the cell and below it a hyaline spot distally extended into 2 teeth, 3 minute 

 subapical spots and between them an oblong strigiform spot, below it two more; the hindwing is of a more 

 intense ochre-colour, in the middle traces of a blurred median band. On the under surface the basal parts of 

 both wings are olive-green, the hindwing exhibits in the middle a broad, behind it a narrower ochreous-yellow 

 macular band and a yellowish-white proximal margin. Widely distributed in South America. 



despeefa. L. despecta Btlr. (Ill i) is above brown, with 2 small square hyaline spots on the forewing. Beneath 



marked the same, at the base and at the proximal margin of the forewmg, and on almost the whole hindwing 

 olive-yellowish. Brazil (Para). 



ferrugineus. L. ferrugineus Plotz (171 f) is above brown, towards the base fox-coloured, the same on the body 



and hindwing of which only the apex is dark brown, the distal margin narrow and the anal angle broader dark 

 bro-wn. On the forewing a minute postceUular hyaline spot between the radial and median vein. Bahia. 



epimethea. L. epimethea Plotz (171 f) is somewhat larger than ferrugineus, the proximal third of the forewing 



brighter and rather sharply defined reddish-yellow, with 3 very fine, small subapical spots. Beneath lighter 

 brown, towards the base and at the proximal margin of the hindwing olive-yellowish, on the hindwing traces 

 of a broad, darker, postmedian transverse band. Brazil. 



cydana. L. cydana Schs. has remained unknown to me and, according to the description, it may belong to 



efimethea. Wings dark bro^Ti, the basal third of the forewing rusty-yeUow. Hindwing thickly haired ochreous- 

 brown, except the costal margin and apex. Beneath hghter brown, at the bases of the wings and at the proximal 

 margin of the hindwing tinted greenish-yellow. Expanse of wings: 46 mm. Petropolis. 



47. Genus: Hyalothyrus Mab. 



Distinguished from the preceding genus chiefly by the posterior tibiae which are without a hair-tuft. 



neleus. H. neleus L. (171 f) is above black, on the fore\ving with numerous small, white hyaline spots, 



the hindwing in the disc and at the proximal margin extensively white, in the <? somewhat brownish, particularly 

 beneath. Widely distributed in South America. 



■priscus. H. priscus Fldr. is described as a dark blackish-brown insect, with 6 white hyaline spots in the 



disc and 5 small subapical spots in a bent row, the hindwing with a large, white, round discal spot. According 

 to 1 $ from the Rio Negro. 



miocris. H. nitocris Cr. (171 f, g) differs from neleus by its entirely black hindwing being white only beneath 



at the base like the body. Surinam. 



leucomelas. H. leucomelas Hbn. (171 g) has much more extensive hyaline spots on the forewing and is well 



distinguished by a large reniform, in the $ almost circular hyaline spot of the hindwing, whilst beneath the 

 hindwing is all white except the broad black border. South America. 



48. Genus: Mionectes Mah. 



It entirely resembles the preceding genus, but the posterior tibiae exhibit only 1 pair of spurs. Only 

 one species. 

 infernalis. M. infemalis Mschlr. (171 g) is above like nitocris except much smaller hyaKne spots, but it is 



easily discernible by the ochreous-yeUow under surface of the hindwing with a blackish-brown apical spot. 

 Guiana. 



49. Genus: Orynopsis Wts. 



It is unlike the allied genera owing to the peculiar shape of the wings, the hindwing with an undulate 



^ border and before the anal angle with a very lobate distal margin. The club of the long antenna is hardly thicker 



than the shaft, the 3rd palpal joint short, a hidden costal fold present. Posterior tibiae only with terminal spurs. 



coehsiis. G. coelestis Dbl. & Hew. (171 g) is above black with a bright slate-blue reflection, large hyaline spots 



and speckled fringes. Beneath the hindMong is of a deep orange-yellow except the black distal margin. Colombia, 

 Brazil.
