HORN EXPEDITION—CARABID^E. 
Note.—It is possible that the specimen on which this species is founded is 
sliglitly immature, and that the normal colour (especially of the elytra) will be 
found to be darker ; and it may be noted that the prothorax has but one impunc- 
tate basal impression on each side, the usual second shoi’ter one, which is a feature 
of high importance in the genus, being wanting. 
Oodes papviceps, n. sp. 
Oval, slightly convex ; upper surface minutely shagreened ; prothorax 
decidedly bi-impressed towards base; elytra convex, finely dentate at humeral 
angles, strongly striate, interstices not elevated; c?' with three basal joints of 
anterior tarsi moderately dilatate (as in O. j/iodesius, Casteln.); prosternum 
margined between coxie. 
Black, shining ; under surface piceous ; legs, mandibles and indexed margin 
of elytra reddish; antennas and palpi ferruginous. Head small, narrow ; vertex 
minutely shagreened ; front obsoletely impressed on each side behind clypeus ; 
eyes (with orbits) reniform, deeply enclosed in orbits at base. Prothorax short, 
transverse (2‘5 mm. x 4'3 mm.), widest about posterior fourth, depressed across 
base, hardly the least declivous to basal angles; sides lightly rounded on posterior 
half, strongly narrowed to apex ; anterior margin deeply emarginate, the emargi- 
natiou becoming much deepei' and subtruncate behind the occiput; base sinuate as 
usual in genus; anterior angles less I’oundeil off than usual in genus ; basal angles 
subrectangular; median line very lightly impressed; basal impressions deep, 
narrow, short, not extending to base ; indexed margin not wide or concave 
anteriorly. Elytra widely oval (5’3 mm. x 7‘5 mm.), decidedly wider than 
prothorax, convex; sides rounded; liase of same width as base of prothorax ; 
basal border forming a short dentiform projection at humeral angles; strife well 
marked, simple ; fii’st, sixth and seventh most strongly impressed, fourth and fifth 
curved inwards at base, sixth and seventh not attaining base; striole at base of 
first interstice strongly impressed; interstices finely shagreened, third bi-impressed. 
Sides of metasternum and metasternal episterna smooth (the puncturation shallow 
and almost quite obsolete) ; lateral parts of ventral segments obsoletely punctate. 
Length, 11 mm. ; breadth, 5'3 mm.

This species has the eyes much less prominent than in most other Australian 
Oodes. It seems allied to O. /atus, Castlen., which is said by Baron Chaudoir 
(Ann. Soc. Ent. Fr., 1882 (6), p. 315) to be from Boebuck Bay, but Chaudoir
