Coleoptera of New Zealand. 125 



Stenellipsis bimaculata. 

 Xylotoles bimaculatus, White, Voy. Ereb. & Terr., Ins. p. 22. 



White's description, though brief, is sufficient to enable 

 us to recognize his species, as he mentions the " bulging middle 

 of the thorax," the anterior and posterior transverse impres- 

 sions of the same part, and the tomentose yellow spot in the 

 depressed part near the base of each elytron. 



Auckland. Sent sparingly by Mr. Lawson. 



Stenellipsis gracilis. 

 ? Xylotoles gracilis, White, Voy. Ereb. & Terr., Ins. p. 22. 



The above-cited description of this species leaves us in 

 doubt whether it applies to our insect, as no mention is made 

 of the "bulging" middle of the thorax, although it is as con-' 

 spicuous as in the allied 8. bimaculata. The elytra are 

 more cylindrical and less ovate than in 8. bimaculata, and 

 are clothed with fine grey tomentum, prettily spotted with 

 brown, and having a brown fascia across the middle and a 

 streak of the same colour behind, near the suture. 



Auckland. Several examples sent by Mr. Lawson. 



Stenellipsis latipenms, n. sp. 



8. latior, elytris oblongo-ovatis, ad humeros thoracis basi fere 

 duplo latioribus. Chalybeo-nigra, snbtiliter cinereo-pubescens, 

 antennis (scapo excepto) tibiisque basi et unguibus castaneis ; 

 thorace breviore, medio rotundato, lsevi ; elytris cinereis, guttis 

 majoribus rotundis lineatim ordinatis, ad basin, in medio et versus 

 apicem in plagas aggregatis. Long. 3 lin. 



A true Stenellipsis, although differing from its congeners 

 by the broader shoulders of the elytra ; the latter have an 

 obtuse elevation near the scutellum and a few punctures 

 arranged in rows ; with this exception the body is smooth and 

 clothed with very fine laid pile, as in the other species. 



Auckland (Mr. Lawson) ; one example. 



P.siLOCNiEiA, nov. gen. 



Gen. Xylotoli affine, sed corpore lineari, et metasterno hand abbre- 

 viate. Linearis, subdepressa. Antenna; corpore paulo longiores ; 

 articnlo primo basi extus subito dilatato, tertio et quarto caiteris 

 multo longioribus. Caput exsertum, inter antennas vix concavum. 

 Thorax fere cylindricus, inerrais. Elytra bumeris valde obliquis, 

 apice singulatim rotundata. Prostemnm inter coxas ut in Xylo- 

 tole planum, apice fortiter dilatatum. Acetabula antica extus 

 haud angulata ; intermedia extus clausa. Femora gradatim in- 

 crassata. Tibia' intermedia? extus emarginatte. Ungues divaricati.
