598 COLEOPTERA 



This very distinct species may be recognised at once by the thorax 

 tumid, almost tubercular in the middle on each side, with the anterior 

 and posterior transverse sulci deeply impressed and united in the middle 

 by a longitudinal dorsal impressed line. The tubercle on each side is 

 coarsely sculptured, and the basal surface is covered with a multitude of 

 fine transverse stria?. The punctation of the elytra extends nearly to the 

 apex, and is interrupted by three raised costae on each elytron ; the apex 

 is tapering, and the suture widely gaping, having on each edge a curved 

 sinuation. The sides and apex of the elytra have a few whitish bristles. 

 The legs are concolorous ; the antenna have a speckled pubescence and 

 are robust. 



Christchurch (Mr. Fereday) ; three examples. 



This species tends to connect Xylotoles with Tetrorea. 



1045. X. bullatUS (Sharp, MS.) Bates; Ann. Mag.Nat. Hist., Aug., 

 1876. Elongates, sub-cylindricus, cinereo subtiliter sparsim, elytris macu- 

 latim, vestitus ; antennis pedibusque testaceo-viridibus ; thorads medio 

 convexo ; elytris basin versus punctatis, tuberculo utrinque centro-basali 

 elongato valde elevato ; antennis infra sparsim setosis ; articulis apice 

 fuscescentibus. 



Length, 2 lines. 



Tairua, near Auckland (Capt. Broun). 



More slender inform than the typical species of the genus ; the elytra 

 have distinct shoulders, but are scarcely broader than the middle part of 

 the thorax. The ashy vestiture appears to be very variable in pattern, in 

 one of the specimens before me being arranged on the elytra in longi- 

 tudinal rows of spots, and in another forming two ill-defined fasciae, one 

 before the middle, oblique, and the other sub-apical, transverse. The 

 centro-basal tubercles are prominent and smooth. 



NOTE. I found two or three individuals at Whangarei Heads ; they 

 are rather greener than those from Tairua. 



1046. X. pictulus, Bates ; Ann. Mag. Nat. Hist., August, 1876. 

 Angustus, sub-cylindricus, castaneus, nigro-plagiatus, nitidus, thoracis 

 limbo maculisque utrinque elytrorum duabus albo-tomentosis ; elytris 

 humeris omnino rotundatis, apice conjunctim rotundatis, basi punctatis ; 

 femoribus tibiisque basi albo-testaceis. 



Long., i j lin. 



Tairua, near Auckland (Captain Broun). 



A small and very distinct species. Integument glabrous, shining 

 castaneous with black clouds on disc of thorax, and in the middle, and 

 towards the apex of the elytra ; scattered white tomentum clothes the 

 sides of the thorax and forms three streaks on the elytra, namely, two 

 elongate at the base, and one curved towards the apex. The body is 

 slightly convex, but the base of the elytra is much depressed. The 

 elytra are not wider than the thorax, and the shoulders are rounded off; 

 the base has a few punctures, and there is a line of the same on each 

 side extending beyond the middle. The antenna are half as long again 

 as the body, and reddish-testaceous. The legs are pale-testaceous, with 

 the club of the femora blackish, and the apex of the tibiae dusky.
