rounded; segments 1—5 of abdomen with angular subventral projections, tubercle enlarged, with many 
little spines “to which various objects adhere”. On Lantana camara (Dyar). —herbaria F. (= sitellaria Guen., 
congruata Walk., indeclararia Walk., croceofimbriata H.-Sch., attendaria Mdschl.) (4 f). Face green, usually 
edged with red. The white costal edge of forewing only distinctly reddened at base; the red terminal line and 
dashes on fringe fine, often rudimentary; abdomen green, with white red-ringed spots which are larger in the 
$. Fabricius, whose type was from the West Indies (not exactly localised) did not notice any red markings, 
hence his form has been identified with Intacta; but Aitrivillius, who has seen the type, refers it here, and the 
“black” cell-dots confirm him. Cuba, Haiti, Porto Rico, ? Santa Lucia. — bonhotei Prout is smaller, the white 
abdominal spots reduced in size, set on a continuous but narrow crimson band. Bahamas. — dorsuaria Prout, 
from Antigua, is larger 23 mm), face wholly green, abdominal spots as in herbaria or better developed, 
cell-dots minute, terminal red line wanting. — intacta Warr. (4 h) has lost all the red colouring in the except 
traces of red band on vertex of head and the excessively minute cell-dots, but the $ differs little from that of 
herbaria, except that the cell-dots are almost entirely obsolete. Dominica. — sanctae-crucis subsp. nov. Sexual 
dimorphism nearly as strong as in intacta. $ quite similar to that, but with (small) white posterior spots on 
the 3rd, 4th and 5th abdominal tergites; $ without red on face and without red terminal line, otherwise as 
that of herbaria. Ste. Croix (Santa Cruz), 1894 (Hedemann), a fine pair in Mus. Wien. 
R. astraeoides Warr. (4 f) has the hindwing marked nearly as in astraea, but is structurally related to 
tenuimargo. Costa Rica to Bolivia and Brazil, described from Ecuador. 
R. capysoides Schaus (5 c) is larger than astraeoides (4 f), fringes without the pure white marks, hindwing 
with a more distinct cell-spot and with the patch at abdominal margin a little broader and less dark, lacking 
the slender posterior extension to anal angle. Systematic position somewhat doubtful; I have no material for 
study. Mexico. 
C\ Antennal pectinations moderate, almost equally developed in both 
sexes, costal vein of hindwing not anastomosing. 
R. astraea Druce (4 f) cannot be confused with any other known species. Hindtibial pencil and terminal 
process in B strong. Palpus in $ with 3rd joint moderately elongate. Mexico (loc. typ.) to Colombia. 
4. Genus: Drya«lopsls Warr. 
A superfluous genus, erected for those species of the Blechroma group of Racheospila in which the B 
antenna in not fully pectinate but merely dentate, with tufts of short cilia. But the last three species are in 
a measure transitional. 
D. morbilliata Feld. (5 c). Rather larger than pulveraria (4 i), with better defined dark bands, dark 
basal patch, cell-dot on hindwing and dark terminal line. “Brazil”, only the type <§ known. 
D. pulveraria Schaus (4 i) is the commonest Dryaclopsis, little variable except in size. From the 
somewhat similar Racheospila conspersa (4 a) it may be known at once by the dark vertex and the white 
markings which accompany the postmedian line. Hindtibia of <$ with hair-pencil but without process. Colombia 
to British Guiana, the Amazons, Peru and Bolivia, the type locality being the last-named. 
D. adjunctaria Dyar. Expanse 24 mm. “Similar to D. pulveraria (4 i), smaller, the discal mark closely 
approximated to the inner line; costa less broadly strigose in brown; submarginal rows of dots punctiform 
on both wings.” Founded on a <$ from Trinidad River, Panama Canal zone. According to a note which 1 made 
on the type, the antenna has pectinations almost as long as diameter of shaft and it would be “perhaps better 
regarded as a tiny Racheospila (Blechroma)". 
D. characta sp. n. (6 k) may possibly prove, on comparison, a form of adjunctaria, as the antennal teeth 
of the inner side of the shaft are, from near the base to about the middle, developed into rudimentary pectina¬ 
tions almost as quoted above. Larger (29—30 mm). Hindtibia of <§ with moderate terminal process. Scheme 
of markings much as in pulveraria (4 i) but with the dark lines stronger, simpler (not founded on whitish 
lunules), the postmedian more highly zig-zag but in its general course much more nearly parallel with distal 
margin; arising in a costal spot about 3 mm from apex, it is four times deeply incurved (in cellules 6, 4, 2 
and at the fold), from 2nd median to hindmargin accompanied proximally by a nearly parallel line. E. Co¬ 
lombia: Upper Rio Negro, 800 m. (Fassl), type S hi coll. -Joicey. Bolivia (Germain) a sharply marked 3 
in Mus. Brit. 
D. leucaspis sp. n. (4 i). In structure and markings similar to the preceding. Abdominal maculation 
very different, the 3rd and 4th segments (sometimes also the 5th) fuscous dorsally, the 3rd bearing a large, 
the 4th a small white spot. Colombia: Muzo, 400—800 m. (Fassl), 3 SB, the type in coll. Prout. Costa Rica: 
Sixola River (Schaus), a $ in coll. Tring Mus.
