Subgenus Hoplolabis Osten Sacken) 
1869 Hoplolabis O.S. Mon. Dipt. N. Amer., part 4, p. 160. 
The subgenus Hoplolabis includes but three known species — the type 
f the group, Erioptera (Hoplolabis) armata, discussed below; EF. (#.) 
tpartita O. S., of western North America; and E. (H.) aszatica Alex., 
rioptera (Hoplolabis) armata O. §. 
1859 Erioptera armata O.S. Proc. Acad. Nat. Sci. Phila., p. 227. 
Erioptera armata is a rather common fly thruout the northeastern 
nited States. A larva was found in the sand along the banks of Fall 
reek, Ithaca, New York, on May 16, 1917. This larva was of the. 
ypical eriopterine form, being elongate, terete, and with the spiracular 
isk surrounded by five subequal lobes. It was placed in rearing and 
ransformed to an adult female on May 31. This larva was found associ- 
ted with numerous hexatomine larvae, such as Eriocera spinosa, E. 
ngicornis, and E. cinerea. 
The following description is from the cast pupal skin. 
Length, about 7 mm. 
Cephalic crest consisting of two moderately large, slightly divergent lobes which are 
cutely pointed at tips; lobes directed strongly outward and bearing a seta on outer face. 
abrum acutely pointed. Labial lobes large, divergent, almost straight across caudal margin. 
heaths of maxillary palpi stout, rather pointed at tips. Pronotal breathing horns broad 
t base, tapering to slender apices, bases conspicuously wrinkled; a small setiferous 
bercle before base of each breathing horn. Mesonotum at crest (Plate LXIX, 373) 
ith numerous short, chitinized points. Lateral angle of thorax with two setae; a strong 
ta above wing axil. Leg sheaths with middle tarsi ending conspicuously before tarsi of 
ther legs. 
Each abdominal segment before posterior margin with a transverse row of slender black 
icules or short bristles on tergum and sternum, and smaller areas on pleura. Lateral 
dominal spiracles distinct. Setae on pleura just ventrad of spiracle, and on tergum just 
ove transverse row of spicules. Female cauda with tergal valves elongated, gently 
curved, unarmed; sternal valves shorter, blunt; at base of cauda, on dorsum of eighth seg- 
ent, four small darkened tubercles which are produced into slender tips. 
Neanotype.— Cast pupal skin, Ithaca, New York, May 31, 1917. 
ubgenus Mesocyphona Osten Sacken) 
1869 Mesocyphona O.S. Mon. Dipt. N. Amer., part 4, p. 161. 
Mesocyphona is one of the larger subgenera of Erioptera, reaching its 
aximum of specific development in the Tropics of the New World.
