72 COLEOPTERA 



In the male, the middle tibia? are slightly curved, and the femora of 

 the hind legs are triangularly dilated, so as to form an acute angle on 

 the hind margin near the apex. 



Found in Canterbury by Mr. Wakefield, and given to me by Mr. 

 H. W. Bates. 



Note. — Structurally, this species seems much allied to our European 

 H. carinatus, but the prosternal process is more compressed laterally. 



137. H. &Wgi\.QX, Sharp ; Entom. Man. Mai::., June, 1876,/. 21. 

 Fuscus, fere opacus, crebre punctatus, pedibus rufis, thoracis lateribus, 

 elytrisque indistincte testaceo-signatis ; thoracis lateribus bene curvatis, 

 antrorsum angustatis. 



Long. Corp., 4^-4! mm. 



This species is very similar to H. wakefiddi, but is rather larger, 

 and ihe sides of the thorax are more rounded and narrowed in front ; 

 the testaceous markings are very indistinct, and the elytra have some 

 obscure longitudinal elevations, which render their surface a little- 

 uneven, and the hind legs are longer. 



Apparently a common species in the province of Auckland ; it has 

 been sent me by both Messrs. Broun and Lawson. 



Note. — Until I had carefully examined this species I considered it 

 to be only a variety of H. wakefieldi, and I have sent it under that 

 name to one or two correspondents. However, notwitl>standing that it 

 is very closely allied to the Canterbury species, I do not now think 

 it will prove a variety thereof. 



138. H. StrigOSuluS, n.s. Va^-iegate; the head testaceous-yellow 

 in front and infuscate on the vertex ; the thorax also yellowish, its apex 

 sometimes, the central part of the base constantly, infuscate ; elytra 

 testaceous-brown, with a sutural streak, two more or less obvious longi- 

 tudinal lines on each, and the margin, pale testaceous ; besides these, 

 there are usually some other pale marks that cannot, very well, be 

 accurately delineated, and the darkest portions are the narrow suture, 

 and a narrow, interrupted line on the outer edge of the sutural streak, 

 which are blackish ; the antennae, unlike the body, are shining, and 

 yellowish in colour, the legs are testaceous, and the tarsi shining brown. 



On comparing this species with the common H. duplex, it will be 

 noticed that the former is larger, with much more robust legs, that its 

 sculpture though somewhat similar, is much finer, and that it has a 

 larger prothorax ; the latter is much less narrowed anteriorly and only 

 near the front angles, which nearly attain the middle of the eyes, so that 

 the sides are very slightly curved, and its base about as wide as the 

 middle, its posterior angles are rectangular but not prominent, and there 

 is a transverse impression near the base. The elytra are widest behind, 

 moderately convex, not perceptibly depressed near the suture as is the 

 case in the preceding species, closely and finely punctured, but other- 

 wise almost uninipressed, the discoidal line of punctiform impressions 

 being quite obsolete. The under-side is piceous and finely punctate. 



The prosternal process is not so narrow as in H. duplex, and less 

 elevated, so that it is nearly plane with the coxae ; the inetasternum.
