INSECUTOR INSCITI^ MENSTRUUS 137 



Cladura autumna, new species. 



Head and antennae yellow ; general coloration yellow, the 

 mesonotum without darker markings ; femora and tibiae yel- 

 lowish, narrowly tipped with dark brown ; abdomen obscure 

 yellow, the tergites indistinctly ringed basally with brown; 

 male hypopygium with the pleurites and appendage stout. 



Male. — Length, 5.5-6 mm.; wing, 7-8 mm. 



Female. — Length, about 6 mm. ; wing, 7.8 mm. 



Generally similar to C. nipponensis, differing as follows: 



Larger. Antennas pale, with long, black verticils, the ter- 

 minal three or four segments darker. Head obscure yellowish. 



Thorax shiny yellow, the mesonotum without distinct darker 

 markings. Legs with the femora and tibiae yellow, the tips nar- 

 rowly but conspicuously dark brown ; legs clothed with rather 

 conspicuous, semi-erect hairs. Wings subhyaline ; veins dark 

 brown, with long, conspicuous macrotrichiae. Venation : Sc^ 

 far before the fork of -/^a+s; basal deflection of Cu^ usually 

 at or before the fork of M,, the fusion of M^ and Cm^ being 

 extensive. 



Abdomen obscure yellow, the tergites indistinctly ringed 

 basally with brown. Male hypopygium with the pleurites short 

 and stout, the single pleural appendage very short and stout, 

 the rounded apex densely set with numerous short spinous 

 setae. Outer gonapophyses shaped like broad, flattened wings, 

 the outer margin fimbriate, the two apophyses together appear- 

 ing somewhat like a bird in flight.

This species is also very close to Crypteria japonica Alex., 

 which is very probably likewise a Cladura. This latter species 

 is still known only from the type females and the male will be 

 necessary to secure an exact definition of the characters. 

 C. japonica (Alex.) has the wings distinctly although faintly 

 tinged with yellowish ; the macrotrichiae on the veins are shorter
