Studies on Tipulidae 11. 321 
form a distinet group, hitherto not found outside of that island, and 
distinguished by the shortness of the auxiliary vein, which does not 
reach beyond the proximal end of the second submarginal cell, the 
smaller size, and the coloring of the wings, which is clearer, and 
has a handsome blue opalescence, either spread all over the surface» 
or distributed in spots. A fifth species, likewise from Ceylon, seems 
to be identical with an african species. 
Eriocera Humbertin. sp. 2. Wings brownish, with two 
broad, hyaline, bluish-opalescent, crossbands; thorax red; abdomen 
velvet-black, with gray crossbands. Length: 9—10 mm. (without 
ovipositor). 
Head and first joint of antennae ferruginous-red; the rest of the 
antennae brown; thorax ferruginous-red, with a faint darker stripe 
in the middle; scutellum and metathorax blackish. Halteres black. 
Abdomen velvet-black; each segment. beginning with the second. with 
a bluish-gray plumbeous crossband at the base; the last segment ferru- 
ginous red; ovipositor reddish-brown. Legs (only the right hind leg 
is left) brownish-red; tibiae and tarsi darker. Wings: pale brownish 
at the extreme base; a broad brown crossband in the middle; it 
occeupies, on the anterior margin, the interval between the origin of 
the second vein and the tip of the auxiliary; on the posterior, bet- 
ween the tips of the sixth and seventh veins; the last quarter of the 
wing is pale brown. The two hyaline spaces (or cerossbands) thus 
remaining between the brown portions of the wing have a beautiful 
bluish opalescense; four posterior cells. 
Hab. Ceylon (Pundel Oya Valley; 3500—3900 feet altitude; 
26. Nov. — 27. Dec. 1859; Mr. Alois Humbert, from Geneva). 
A single female in the Museum in Geneva. 
NB. The tip of the auxiliary vein a little anterior to the proxi- 
mal end of the 24 submarg. c.; the 15 subm. c. and the 1°t post. ce. 
are of equal length; the great crossvein at the very base of the 
discal cell. 
Eriocera meleagrisn. sp. @. Thorax orange-red, with 
black stripes; wings subhyaline, with a cerossband formed by four 
opalescent spots; two similar spots near the basis. Length: 7—8 
mm. (without the ovip.). 
Head reddish brown, more brown on the vertex; antennae and 
palpi brown. Thorax yellowish-orange; the usual dorsal stripes well- 
defined, brownish-black, with narrow orange lines between them; a 
black stripe on each side between the root of the wings and the
