Moderately stout; pale cinereous, more or 

 less albescent. Head well rounded, not very 

 prominent, the fastigiutn of vertex very ob- 

 scure with no median carina, the frontal costa 

 not very broad, feebly sulcate, punctate 

 .above; antennae a little shorter than the hind 

 femora (?), testaceous, infuscated in apical 

 half by alternating bands of obscure fuscous. 

 Pronotum brownish fuscous on metazona, 



pale cinereous on prozona, the lateral carinae 

 bluntly rounded on metazona and hardly 

 prominent; process of metazona rounded ob- 

 tusangulate. Tegmina densely reticulated 

 except the apical fourth, brownish fuscous at 

 base, beyond dull cinereous, twice not very 

 conspicuously banded with dull fuscous, with 

 signs of a third band, and with obscure fus-

BV HARRISON G. DYAR, WASHINGTON, D. C. 



Mecocevas iiitocris Cram. The larva has 

 not been previously described. Druce gives 

 full references in the Biologia Cent. -Am., 

 Lep. Het., ii, 94. 



Egff. Cylindrical, the ends rounded, one 

 end a little more taperingly so than the other; 

 a scarcely perceptible flattening of the cylin- 

 der, parallel to the leaf as laid. Twelve neat 

 low ribs, reaching almost to the smaller end, 

 becoming dotted at termination; stopping 

 abruptly at the larger (raicropylar) end in a 

 circle of large, quadrangular, indistinctly 

 edged cells, at the inner angles of which are 

 a circle of white dots, one for each rib. Within 

 this the micropyle is somewhat coarsely re- 

 ticulate. Ribs thickly crested with a double 



alternating row of white dots. Cross-stria- 

 fine, parallel, faint. Fine dark green; the 

 ribs and circle of dots appear white. Size 

 .65 X -55 X .50 mm. 



Slage /. Head rounded, not bilohed, 

 brown-black, not shining; width .3 mm. 

 Body cylindrical, slender, feet normal; cen- 

 tral parts of segments bearing tubercles i and 

 ii larger, coUai-ed, 2-annulate, the interseg. 

 mental parts smooth ; ends shrunken. Dark 

 vinous, almost blackish, the slender, inter- 

 segmental parts of joints S to 9 pale, sordid 

 whitish with dorsal and subdorsal vinous 

 lines, so that the body looks obscurely dark 

 vinous banded. Tubercles small ; setae black, 

 stiff, iv behind the spiracle; on thorax ia to
