1042. X. segrotUS, Bates; Ann. Mag. Nat. Hist., July, 1874. X. 

 elongatus, angustus, omnino fulvo-testaceus, subtiliter griseo-pubescens ; 

 elytris, M. apice dehiscentibus, siflgulatim prolongatis, perparum divart- 

 catis ; F. acute conjunctim rotundatis. 



Long., 2j-2f lin. 



Similar in form to X. nanus, but always of a tawny testaceous colour, 

 with fine scant grey pubescence, arranged more or less in lines on the 

 elytra. The antennce are not ringed with dark colour, but pallid like the 

 rest of the body, or at most a little browner at the extreme tips of some 

 of the joints. The elytra are relatively much longer, and are narrowed 

 and prolonged towards their apices ; in the male strongly dehiscent at 

 the suture ; they are a little wider at the base than the base of the 

 thorax, and have the usual lineated punctation from the base to the 

 middle. The sutural stria is deeply sunk. 



Auckland, six examples (Mr. Lawson) ; Christchurch (Mr. Fereday), 

 three examples. 



NOTE. I think the species may be found in most places, I found it 

 wherever I collected. The punctation at the base of the elytra varies 

 considerably. In some specimens there are only two simple rows of 

 punctures ; but in others there are two or three rows, each composed of 

 a large number of punctures, arranged often without order. The differ- 

 ence is not sexual, but the two varieties are strongly pronounced. 



1043. X. pUlchellUS, Bates; Ann. Mag. Nat. Hist., July, 1874. 

 X. nano proxime affinis, at differt elytris magis ellipticis fusco fasciatis, cor- 

 pore subtus dense cinereo-tomentoso. Parvus, nigro-cupreus, aluta- 

 ceus, pube grisea vestitus ; elytris ad humeros angustis, regulariter 

 ellipticis, apice conjunctim subacute rotundatis, plagis fuscis magnis 

 duabus fasciiformibus, altera pone medium, altera apicali. 



Long., 2.\ lin. 



Closely resembling X. nanus, but the elytra decidedly more elliptical 

 in form i.e., narrower at the shoulders and more regularly rounded on 

 the sides, the apex being jointly rounded; the surface is of the coppery- 

 black or dark-drown of the full-coloured examples of X. nanus; and the 

 grey pubescence is spotty in the same way on the elytra, but the dark 

 patches lie in two places, forming irregular broad fasciae, one at the 

 middle and the other at the apex. The antenna are rather more slender, 

 and have a larger portion of the apices of the joints pitchy-black. 

 Beneath, the insect is more densely clothed with grey pubescence. 



Christchurch (Mr. Fereday) ; one example. 



1044. X. SCiSSicauda, Bates; Ann. Mag. Nat. Hist., July, 1874. 

 X. elongato-ellipticus, castaneo-fuscus, griseo-pubescens ; thorace medio 

 utrinque dilatato-tumido, supra sulcis duobus transversis fortiter impressis, 

 alteroque dorsali, basi subtiliter transversim multistrigoso ; elytris hume- 

 ris paululum productis, obliquis, postice gradatim attenuatis, apice dehis- 

 centibus ibique sutura emarginata, supra fere ad apicem lineatim punc- 

 tatis, costulisque utrinque tribus. 



Long., 3^-4 lin.
