rating to external margin. Sub-median with a basal upward projection. 

 Antennje resembling those of Ot^ceticus, widely bi-pectinate at ba.'^ul 

 half, terminal joints with small serrations, flexuous, recurved. 



Female, apterous, vermiform. 



Type : GlJceficus coni/crnrum, Harris. 



This genus differs from the closely scaled species of (Eceft'cus in many 

 particulars, though a near ally. It resembles greatly the figure of 

 Jnimnhi (Jlchroa H-S., from Venezuela, and may be identical with it. 

 8iDce, however, no specific or generic diagnosis is given of the South 

 American species, I cannot accept that genus, while the figure differs 

 in detail. The secondaries are more reduced and rounded, and the 

 nervulation is different. The first m. nervule of the primaries is not 

 furcate.* The antennae seem equally pectinate from base to tip, the 

 latter not flexuous. The genital organs have a different representation. 

 Ht/mcnnpsj/chc contains two species, differing slightly from one another 

 in CS ) structure, as indeed is the rule rather than the reverse in the 

 present Sub-family, as well as in the Cei-atocampadse. 



Hymenopsyche thoracicum, n. s. 



Smaller than H. coni/erarum. "Wings more sparsely scaled. Tho- 

 racic region above, and supra caputal parts, clothed with pale, some- 

 what sericious hair. Elsewhere the rather coarse and stout squamma- 

 tion of this little species is brownish-black. First m. nervule of the 

 primaries strongly furcate. A cell is formed by an ob.?olete '' vein," 

 running from the base of the wing to the angulated portion of the sub- 

 median nervure. This is obsolete in my specimens of //. coinferarum. 

 M. nervure not distinctly geminate at base. Genitals displayed, con- 

 sisting of a flattened, corneous, acutely cordate piece, from beneath 

 which a slender, blunt, longer process is protruded, held in a lower 

 basal sheath, embraced by the lateral claspers. Two specimen.s. Exp.

PSYCHONOCTUA. nov. gen. 



In the male the antennae are short, closely bi-pectinate laterally, to 

 half their length from the base ; the pectinations are fine and rather 

 close, and decrease suddenly at the middle of the antennte, the termi- 

 nal half of which is provided with very short processes, appearing sim- 

 ple to the unassisted eye. Scape moderately prominent and tufted. 



*In a single individual of H. coni/crarum, that I have before me, this furca- 

 tion is obsolete on the right primary.
