200 COLEOPTERA 



tiliter punctato denseque pubescente ; clytris profunde striatis ; aniennis 

 articulis secundo et tertio vix abbreviatis. 



Long., 41-5^ mm. 



This species varies somewhat in colour ; the thorax is generally 

 darker than the elytra, the breast is reddish, and the ventral segments 

 nearly black except at the base and extremity; though very similar to 

 Betaniion frontalis, it may always be distinguished by its finely, densely, 

 and evenly punctured thorax. 



" On various shrubs at Tairua ; active : not uncommon"' (Captain 

 Broun). 



PanspoGus. 



Sharp: Ann. Ma^^. Nat. Hist., May, 1877. 



The two specimens of the minute insect described below are in bad 

 condition, and 1 cannot ascertain thoroughly all their characters ; but 

 they show one peculiarity which in itself is sufficient to mark them off as 

 a distinct genus, viz., that along the under-side of the thorax, close to 

 and parallel with its border, is a longitudinal furrow, such as is seen in 

 many Eiicneniidcs ; besides this I can say that the forehead is rounded 

 in front and limited by a raised line, the clypeus is extremely reduced 

 and concealed, the femoral portion of the coxal plate pretty well 

 developed, the trochanteral portion short and only a little longer than 

 the femoral portion. The tarsi are small, simple, and slender. The 

 relationship appears to be with Betarmon. 



506. P. g'uttatUS, Sliarp; Ann. Mag. Nat. Hist., May, 1877. 

 P. miuutiis, angustulus, nigricans, prothoracis angulis posterioribus 

 maculisque quatuor in elytris, aniennis pedibusque testaceis, antennis 

 extrorsum fuscis ; prothorace minus elongato, obsolete punctato, nitido 

 sed evidenter pubescente : elytris striatis, striis internis sat profundis. 

 externis obsoletis; macula testacea humerali elongata, altera ante-apicah 

 magna. 



Long., 2 mm. 



This very minute insect is one of the smallest of the Elateridce, it 

 being rather longer and narrower than the European Cryptohypnus 

 miniitissiniiis. 



Sent from Tairua by Captain Broun, who says that it is evidently 

 very rare, and that he has only found three individuals. 



507. p. tenebrosus, n.s. This species is of the same length as 

 but narrower than the preceding one, and the antennae are considerably 

 longer; the body is of a shining pitchy-brown colour, the legs, two basal 

 joints of the antennae, and thoracic hind angles, are of an infuscate 

 testaceous colour. 



The antenme are as long as the elytra, with a rather small second 

 joint, which is of a quadrate form ; the third and fourth joints are 

 filiform, the former the longer ; joints 5-10 are sub-serrate ; the 

 terminal elongate-ovate. Head finely punctate. The thorax is narrowed
