190 Mr. H. E. Andrewes’ Notes on Synonymy 
Chlaenius puleher Nietn. race asper nov. Length 18:0 
mm. Width 7°75 mm. 
Black: head and prothorax metallic green, both cupreous on 
disk, elytra greenish-black; epipleurae and margins of elytra to 
stria 8, margin of ventral surface, and legs (except coxae) flavous, 
palpi and antennae brown (latter lighter at base); underside slightly 
iridescent. Pubescence short, yellowish, rather sparse. 
Head (3-3 mm. wide) rather flat, vertex finely rugose, some 
striation near eyes, punctate at back and sides, eyes prominent, 
joint 3 of antennae a third as long again as 4. Prothorax (4-75 mm. 
wide) slightly transverse, quadrate, flat but declivous to front 
angles, sides of base oblique, sides evenly rounded but rather wider 
at base than apex. hind angles obtuse and rounded, median line 
and basal foveae both clearly marked but shallow, surface finely 
rugose, coarsely punctate, more finely at sides, more closely along 
base. lylra nearly parallel, but widest a little behind middle, 
border angled at shoulder, crenulate-striate, striae with a row of 
fine punctures along each side, intervals convex, rather coarsely 
punctate, odd ones slightly raised and more or less smooth along 
median line, 8 more finely and closely punctate. Underside smooth 
and polished along median line, prosternal process bordered and 
setose at apex, all episterna and sides of metasternum closely 
punctate, metepisterna not quite half as long again as wide, sides 
of ventral surface finely rugose, punctate near base. Front femora 
($) without tooth, tarsi glabrous on upper surface. 
Closely allied to C. pulcher Nietn. (= C. cinctus Chaud., not 
F.), but that species is shorter (16 mm.), with smoother 
vertex, head, prothorax, and elytra more finely punctate, 
sides of prothorax slightly simuate before hind angles, 
which therefore though obtuse are sharper, marginal 
channel narrower, especially behind. In C. pulcher, too, 
the elytra are generally a deeper black (sometimes bluish), 
and the even intervals, like the odd ones, are often smooth 
and polished along median line.

Note.—In Ann. Mag. Nat. Hist. (9), vii, 1921, p. 406, 
I recently described a species of Omophron under the name 
of O. gemma. I find this name is preoccupied, and I there- 
fore desire to substitute for it the name of O. gemmeus.
