This dark reddish male was taken June 16, 1906 in a trap lantern ° 
at Newport, N. Y., and similarly captured July 14th at Huguenot 
Park, Staten Island, N. Y. 
Male. Length 1mm. Antennae probably longer than the body, 
sparsely haired, dark brown; fourteen segments, the fifth with stems 
two and one-half and three and one-half times their diameters 
respectively. Palpi; the first segment subquadrate, swollen distally, 
the second, third and fourth, each subequal and successively more 
slender; face sooty yellow. Mesonotum dark brown, submedian 
lines yellow, each sparsely clothed with fine setae. Scutellum yel- 
lowish brown with sparse apical setae, postscutellum dark yellowish. 
Abdomen dark reddish brown with the basal and terminal segments 
yellowish, rather thickly yellow haired. Wings hyaline, costa 
reddish brown; halteres pale yellowish basally, fuscous apically. 
Legs a nearly uniform dark brown, lighter ventrally; claws rather 
long, bent at nearly right angles, simple. Genitalia (pl. 20, fig. 1); 
basal clasp segment stout, an angulate lobe at the distal third; 
terminal clasp segment swollen at the base, long; dorsal plate broad, 
deeply and narrowly incised, the lobes irregularly truncate; ventral 
plate swollen at the base, slender at the distal fourth, expanding 
apically, broadly emarginate, setose. Type Cecid. 325.

This genus was erected for certain small, yellowish species with 
simple claws bent at nearly right angles and a very long, broad, 
very deeply and broadly emarginate ventral plate with long, slender, 
more or less divergent lobes. The dorsal plate is short, deeply and 
roundly emarginate, the lobes being broadly and roundly emarginate 
and with the lateral and internal angles produced and setose. The 
typeas ‘Cecidomy1a,lobata Pelt. 
The type species was captured on white clover and possibly lives 
upon fungus, since H. fungicola Felt was reared from a 
fungus on nectarine.
