Variation in size as well as in the strength of the armament 
is decided. The extremes of the three males from Kauai measure 
as follows; length of body 11.7-13.5, length of pronotum 1.55- 
1.9, width of pronotum 1.55-1.8, length of tegmen 3.2-3.8, ex- 
posed length of wing 1.84-1.97, length of forceps 4.2-6.1 mm.

Moscou, part 2, p. 2 [2 ; Nura Ellia Mountains, Ceylon. ] 
This species is apparently nearest L. friihstorferi Burr, de- 
scribed from Lombok. It differs in having the meso-distal por- 
tion of the abdomen brown, often as light as the forceps, the 
almost unicolorous limbs and the moderately prominent though 
very small male pygidium. From the description we are unable to 
say whether the female forceps and pygidium show other differ- 
ences. 
The species clearly shows Indo-Malayan, Melanesian or 
7 
Oceanic, rather than American affinities. 
This material was first believed to represent an undescribed 
species and the following treatment was prepared. We have not 
deleted this, as the species has never been thoroughly diagnosed. 
There is little question that pilicornis has been introduced 
from the Orient. 
Kaimuki, Oahu, Hawaii. February 19, 1921. (P. H. Timber- 
lake. ) 
Description of male: Size very small, form slender. Head microscop- 
ically very finely but thickly pilose, shining; weakly cordiform, owing to a 
very weakly indicated obtuse-angulate emargination of the caudal margin; 
the medio-longitudinal suture weakly indicated as a bare line in occipital 
portion. Eyes small, about three-fifths as long as cheeks. Antennae with 
13 joints; the first large, as long as the third plus twice the length of the 
second, expanding suddenly near base, thence with sides parallel; second 
minute; third elongate, cylindrical, expanding very feebly and evenly distad; 
fourth elongate ovate, three-quarters as long as the third; the fifth elongate, 
weakly pyriform, nearly as long as the third; succeeding joints similar, but 
increasing slightly in length distad, the longest nearly four times as long 
as. broad.
