form of A. elevatus; the former, bearing the number 46, is 
therefore replaced by this species. 
1328. Anchomenus helmsi, n. sp. (Sharp, “ Ent. Mon. Mag.,” vol. 
XVIII, p. 47, July, 1881).—Sat elongatus, parum nitidus, nigro- 
piceus, antennis, palpis pedibusque rufo-testaceis ; prothorace 
parvo, lateribus postice fortiter sinuatis, angulis posterioribus 
rectis, basi utrinque profunde impresso; elytris sat convexis, 
lateribus valde curvatis, profunde striatis, prope apicem fortiter 
sinuatis. 
one.,.11 > Jat, 4:mm. 
Similar in appearance, and more particularly in colour, to 
A. otagoensis (Bates), but abundantly distinct, rather smaller, the 
upper surface less opaque and not so flat, the thorax shining, 
the elytra deeply striate. The ¢horvar is much rounded at the 
sides, and much constricted behind, the posterior part is quite 
straight, and the hind angles are abruptly marked, and quite 
rectangular ; the surface is not flat, but is deeply impressed on 
each side at the base; the mesial longitudinal channel is very 
distinct. lytra rather short, the sides and shoulders much 
curved ; the striz deep, but not punctate; the interstices are 
broad and but little convex, the three punctures on the third 
moderately distinct. There is but little difference between the 
male and female, even the front farsi of the former being but 
little dilated.

1329. Tropopterus marginalis, n. sp.—Shining, brownish-black, 
antenne, legs, trophi, and elytral margins rufescent. Head bi- 
sulcate at each side, the grooves not connected in front ; epistome 
with two punctures. /vothorax sub-quadrate, convex, rounded 
laterally, sinuously narrowed towards the acute, slightly pro- 
minent hind angles; side margins somewhat flattened posteriorly ; 
basal foveze broad, rather shallow, and finely punctated ; its sur- 
face, save a few small basal punctures and dorsal striz, unim- 
pressed. L/ytra convex, broadly oval, marginated, much broader 
than thorax, rather feebly punctate-striate, the four inner strize 
of each only distinct ; interstices plane, the seventh bordered by 
a sharp, curved carina extending from near the posterior femur 
to the apex, the sides bear a few punctiform impressions. The 
three basal joints of the aztenng are nude. Extremely like an 
Odpterus, but the sutural stria of the wing-case is not recurved at 
the apex. Allied to 7. salczcollis , of a broad, moderately convex 
form, having the frontal foveze separated by a broad rather than 
carinated interval, and the thoracic fovee not all sulciform. The 
elytral sculpture of 7. placens is decidedly coarser. 
Length, 31% ; breadth, 1% line.

1330. Trichosternus putus,n.sp.—Colour black tinged with red and

piceo-rufous; oblong, moderately convex. Head moderate,
