On new Species of Asiatic Lepidoptera Heterocera. 119 



Dyson from Venezuela. As the species will therefore not 

 come within my limits in the ' Biologia Centrali-Americana,' 

 and as I have been led, to some extent, to indorse one of the 

 gravest of Gray's errors, I have thought it best to make these 

 corrections here, concluding with a more accurate description 

 of the animal. It appears to differ from its known con- 

 geners, not only in colour, but in the total absence from its 

 fur of the flattened channelled spines which are characteristic 

 of all the species of the genus except II. anthophilus (F. 

 Cuv.) *, a doubtful form, described from a single immature 

 example, which Prof. Peters believes to owe the softness of 

 its pelage to its youth f. 



Heteromys hicolor. 

 Perognathis bicolor, Gray, P. Z. S. 1868, p. 202 (descr. orig.). 



Ears with the notch apparently bounded by two lobes ; tail 

 clad with short fine stiffish hairs ; fur rather long, sparse, with 

 no under-fur, somewhat harsh, but not in the least bristly. 

 Colour above uniform dark brown, which extends to the out- 

 side of the limbs ; feet dusky, edges of cheek-pouches and 

 all the lower parts white, the hairs all uniform in colour 

 throughout their length. Approximate measurements (of the 

 mounted specimen) — length of head and body about 3*75 inches, 

 of tail 3 inches, of hind foot 1 inch.

Primaries deep purple ; three parallel longitudinally oblique 

 whitish dashes at the base, the third emitted from near the 

 base of inner margin ; three transversely oblique series of pale 

 greenish-blue spots, the first consisting of three, the second of 

 seven, the third of four spots, some of which, however, are only
