20 Mr. R. M‘Lachlan on some 
M. de Selys were identified by him with a species from the 
island of Trinidad standing under a MS. name in his collec- 
tion. At present I consider my insects as O. clara, and 
hesitate to describe them as a local race until we know more 
about the possible effects of locality as causing variation in 
the structure of the appendages in this genus. 
I think Ortholestes may conveniently head the “ légion.” 
Megalestes major, Selys. 
The original locality given for this species was ‘ Inde 
méridionale.” I am not in a position to say this was in- 
correct ; but all the numerous recent examples I have seen 
have been from North India, and, according to special localities, 
it is probable it is found the whole length of the southern 
slopes of the Himalayas, and sometimes at great elevations. 
Archilestes californica (Selys, MS.), sp. n. 
Wings hyaline. Pterostigma ochreous, dilated, 3 millim. 
long, surmounting 383 cellules, enclosed in thickened black 
nervures ; 12-13 postnodal nervules in the anterior wings. 
Neuration black, but the median nervure and the costa exter- 
nally are yellowish. Nodal sector commencing 14 cellules 
after the nodus in the anterior and one cellule after in the 
posterior. 
Head above dark brownish, slightly varied with paler, 
clothed with sparse cinereous pubescence, with a cuneate 
blackish spot on either side enclosed in pale lines; labrum 
olivaceous; mandibles shining black at the tips; labium 
and back of head whitish yellow. Prothorax blackish, its 
hind margin regularly curved and narrowly yellowish, and 
there is a semicircular line of the same colour on either side. 
Thorax brownish above ; on either side of the dorsal crest is 
a long blackish space completely enclosed in fine yellowish 
lines ; sides pale yellowish, with a large oval isolated black 
(or bronzy-brownish) median spot, whitish pruinose above 
the posterior legs; interalar area slightly pruinose. Legs 
yellowish; a line before the apex of the femora externally 
(nearly complete on the intermediate), tibize above, tarsi 
and spines black. Abdomen greyish brown, dark brows 
above after the sixth segment (there are vague indications 
that the ninth and tenth may be paler in lite), the sutures 
darker, and there is a fine blackish ventral line. 
g. Tenth segment with an elevated dorsal carina, the 
margin with a deep triangular excision. Superior appenda veg 
forcipate, black, the apices touching but not anddeal
