as in forewings ; both wings crossed by unmeruus cnrved grey lines, variable in 

 intensity.

 and abdomen coucolorous. 



Expanse of wings : 16 mm.

Mesocolpia gen. nov. 



An offshoot of Chloroclystis, with which it agrees in the neuration of the 

 forewings; distingnished by several peculiarities in the S. The costa of fore wing 

 is swollen at two-thirds, and bears a slight fringe of hairs ; the inner margin is 

 concave. The hiudmargin of both wings is broadly bilobed, containing a strong 

 rounded sinus in the middle. The underside of both wings towards the hindmargin 

 below the middle bears tufts of black hair, which are especially developed in the 

 hindwings, where the abdominal margin is also fringed, and the cell is somewhat 

 puckered and distorted, and clothed with spots of opalescent scales. The abdomen 

 beneath and the anal segments are likewise tnfted with hair. In the hindwings 

 of the S the cell is broad and shorter than half the wing ; the discocellular 

 concave ; veins 6, 7 on a long stalk ; .5 from above the middle of discocellular ; 

 3 and 4 short-stalked, and 2 close before end of cell. The mouth parts and legs of 

 the only S are too much damaged to be described.

 concolorous. 



Hindwings : similar, but the whole costal half of wing whitish, unmarked. 



Underside the same, but with the markings more confused. Head, thorax, and 

 abdomen concolorous with wings.
