Ocean). Indeed it is not at all certain that I should describe 
the present specimens as representing a new species. But as 
I examine groups of specimens of the two lots I can easily 
;in(l surely distinguisli ihcni as (if twd distinct forms. The 
.\llaiuic specimens arc rc-ularly larger, darker, with more 
lironiiunced markings, mure pniduced anlcriur part of head, 
more strongly angnlatcd melalhorax and less anguLaled 
l)roUior;ix. The arrangement of die hairs and prickles of the 
lateral margins of Uie heail is dilTereni. ihe male genitalia are 
not identical, etc., etc. I'.ut it is all \ery diflicult and wearying, 
this constant attemi)l to gi\-e limits to a species; this constant 
attem])t to conventionalize unconventional Nature. 
Alak-. lcn.>;th _'._^ inni.. width .(jo mm., head, length .82 mm., width 
.82 mm. ; head and prothorax dark goklen brown, metathorax and abdo- 
men pitchy brown. Head with produced clypeus, with narrow clear 
anterior margin with shallow rounding emargination ; signature distinct 
with posterior point unusually produced, acute and blackish ; only two 
short prickles on either side of clypeus ; antennas with 2nd segment as 
long as 3rd and 4th together ; temporal and occipital region broad ; four 
inconsi)icuous hairs on each postero-lateral temporal margin and a 
lungish liair from each eye; occipital bands fairly distinct. 
Pnithorax flatly rounded behind, metathorax sharply angulated ; 
posterior margin of metathorax with conspicuous series of pustulated 
hairs. Abdomen about as broad as long, and with series of pustulated 
hairs along posterior margin of each segment, as shown in fi.g. i ; pleura 
of abdomen projecting laterally so as to give the lateral margins of the 
abdomen almost a serrate appearance: transverse blotches blackish 
brown, covering the whole dorsal surface and thus giving the dorsum of 
the whole abdomen a continuous blackish or pitchy brown color. 
F'emale, length 2.4 mm., width 1. 06 mm.; head, length .82, width 
.82 ; dorsum of first adbominal segment entirely covered by the trans- 
verse blotches, blotches of 2nd segment not quite meeting at middle, and 
of 3rd, 4th and 5th more widely separated, of 6th about as wide apart 
as of 2n(i, and of 7th, 8th and 9th entirely covering the dorsum of each
