NEW MICROLEPIDOPTERA FROM MEXICO. 



BY AUGUST BUSCK. 



The following new species are part of extensive collections 

 of Lepidoptera, received from Mr. R. Miiller in Mexico City. 



The species here described are not represented in the ma- 

 terial treated in Lord Walsingham's part of the Biologia Centrali- 

 Americana, now soon to be concluded, and are published now 

 so as to be available for the final list of species in that paper. 



Genus METOPLEURA, new (Gelechiidte) 



Type: M. potosi Busck. 



Second joint of labial palpi very long, porrected, but slightly curved up- 

 ward, clothed with compressed scales, which form somewhat roughened 

 sharp anterior and posterior edges; terminal joint one-third as long as 

 second, compressed, pointed. Maxilary palpi rudimentary. Tongue well 

 developed, scaled, spiraled. Antennae simple, shorter than the fore wings. 

 Fore wings ample, elongate; costa and dorsum straight, parallel; apex 

 produced, pointed; termen oblique, slightly sinuate below apex. 11 veins; 

 7 and 8 coincident, to costa; rest separate; 2 from before apical third of 

 the cell; 3 and 4 approximate from the end of the cell; 11 from the middle 

 of the cell; 6, 7,8, 9, and 10 equidistant; 1 furcate at base. 



Hind wings much broader that the fore wings; costa and dorsum nearly 

 straight; apex bluntly pointed; termen evenly rounded, with a slight sin- 

 uation below apex. 8 veins; 3 and 4 closely approximate, nearly connate; 



6 and 7 approximate; 5 cubital; S anastomosing with radius before the 

 middle of the cell. Posterior tibiae nearly smooth, but somewhat rough- 

 scaled above. 



Allied to and rather similar in general habitus to Ac rot y pin 

 Walsingham, but differing in the palpi, and in having veins 



7 and 8 coincident in the fore wings. 



In my synoptic generic table this genus runs to I larpuidia 

 Ragcnot, which is unknown to me in nature, but which would 

 seem to agree with the present genus in venation; the very 

 different labial palpi with the short terminal joint will suf- 

 ficiently differentiate the present genus.
