COLEOPTERA. 



Oroup Melandryidae. 

 Sll.'i. Allopterus stmulans sp. nov. Geii., Man. N.Z. Coloopt., p. 790. 



Eloiij^utc, sliji^htly tapering towards l)oth extromitios, a little transversely 

 convex, subopaque, covered with slei»der decumbent greyi.sh- yellow hairs, 

 variegate ; antennae, legs, head, and thorax fuscous ; the palpi, tibial spurs, 

 And knees more or less testaceous ; elytra pale testaceous, with the following 

 fuscou.s marks —a large cordiform one at the middle of their base ; one at 

 each shoulder touching the central one. and prolonged backwards along the 

 side margin to the middle femur, near which an oblique irregular fastiii 

 extends inwards but does not reach the suture ; ijehind this ;i broad l)Ut 

 paler one. which is nearly straight in front but does not reach the apex, 

 extends nearly right across the elytron. 



Ilrnd finely and closely punctate. Thorax of equal length and breadth, 

 moderately narrowed towards the deflexed front angles, the base slightly 

 obtusely prominent at the middle, and a little sinuate towards the obtuse 

 Angles ; a central linear impre.ssion at the base does not extend to the 

 middle of the disc : there is a short oliliipie basal impression near each side : 

 its sculpture is tine, and seems to assume the form of short transver.se lines. 

 Sculrllitni transverse. Eh/tra with shari)ly separately rounded apices, 

 the suture simple and a little elevated ; their sculpture, near the base, is 

 like that of the thorax, but becomes less distinct behind ; on each there 

 are 3 irregular feeble costae, and several series of fine shallow obsolete 

 punctures. 



Eyes large, strongly tran.sverse, not notched in front. Antennae fili- 

 form, reaching beyond the middle femora, '2nd joint hardly a third shorter 

 than the following one. Tibiae sim])le, their spurs minutely pectinate ; 

 posterior tarsi rather longer than the tibiae, penultimate joints of all con- 

 cave above but entire in front. Maxillary i)al})i elongate. sul)serrate. their 

 terminal joint scarcely cultriform. 



Underside fuscous and finely pubescent. 



In coloration and elytral marks much resembling A. caveUi, without the 

 well-marked intrahumeral impressions of that species, which, moreover, 

 is much sm;iller. with a shorter 2nd antennal joint and somewhat different 

 sculpture. 



Length, 3 lines ; breadth, | line.

Elongate, subdepre.ssed, moderately shining ; black, legs and palpi 

 fuscous ; head and thorax scantily clothed with slender, suberect. the 

 elytra more closely with decumlx'iit. ash-coloured |)ul)escence. 



/lead broader than thorax, much narrowed lu'hind the large and promi- 

 nent eyes, with an elongate imjiression Itetween these ; it is coar.sely punc- 

 tured, liut more (inely and very closely behind. Thorax slightly broader 

 than long, widest at or just before the middle, moderately rounded there 

 but narrowed behind ; its surface with 2 small, slightly raised, smooth 

 spots in front, and some irregular, almost smooth, linear spaces on the disc, 

 which is much less doselv p\mctured than the sides. Seutelluni closely and 

 minutely punctate. Eh/tra nearly twict- the breadth of thorax at the base, 

 Hubparallel, or oiilv just |)erceptibly narrowed posteriorly ; they are coarsely 

 And moderately clo.sely but not obviously rugosely punctured.
