472 COLEOPTERA. 



3975. Luperus quadricoUis sp. nov. 



Elongate, nitid, aeneo-cyaneous, legs and antennae fuscous. 



Head nearly as broad as thoi'aric apex, not quite smooth. Thorax of 

 about equal length and breadth, slightly convex, its sides finely margined, 

 not quite straight, very feebly and evenly rounded, the base slightly curved 

 towards the sides, with obtuse angles ; disc distantly and finely yet quite 

 definitely ])unetate. Scutellum small, triangular. Elytra rather broader 

 than thorax at the base, hardly four times its length, with broadly rounded 

 apices, shoulders not prominent but scarcely at all narrowed or rounded ; 

 they are moderately finely, closely, and rugosely punctured, less distinctly 

 and closely neai' the shoulders, which are without any well-marked 

 impressions. 



Antennae not reaching posterior femora, moderately slender, their 3rd 

 joint short, hardly any longer than 2nd ; joints 4-11 about equal. 



Legs moderately elongate, tibiae straight ; basal joint of posterior 

 tarsi as long as 2nd and 3rd. 



The small size, subquadrate, evenly convex thorax, different shoulders, 

 less elongate and slender legs and tarsi, and somewhat abbreviated 3rd 

 antennal articulation, serve as good distinguishing characters. 



Length, 3 J mm. ; breadth. 1 J mm. 



Moa Basin. Another unique from Mr. T. Hall. 



3976. Luperus xenoscelis sp. nov. 



Subdepressed. moderately elongate and nitid ; viridi-cyaneous, tibiae 

 and basal half of antennae light fuscous, remaining joints and the femora 

 darker. 



Head as broad, the large eyes inclusive, as front of thorax, with a few 

 fine punctures just behind the eyes, and some fine hairs, antennal orbits 

 slightly elevated. Thorax subquadrate, a little broader than long, its sides 

 distinctly marginate, nearly straight, only very slightly narrowed behind, 

 front angles slightly incrassate, base slightly rounded near the sides so 

 that its angles are not quite rectangular ; disc without depressions, finely 

 yet quite distinctly, moderately closely but irregularly punctured, more 

 distantly between the middle and sides, between many of these punctures 

 there are a few minute ones. Scutellum small. Elytra thrice the length 

 of thorax, rather broader than it is at the base, the shoulders scarcely at all, 

 the apices broadly rounded ; their surface plane, suture simple, moderately 

 closely and rather finely punctate, with very minutely sculptured inter- 

 stices. 



Antennae extending to beyond intermediate femora, their 3rd joint 

 scarcely any longer than the suboviform 2nd ; joints 4-11 moderately 

 elongate, each slightly narrowed towards the base. 



Legs moderately stout ; posterior tibiae below the middle, along their 

 front face, distinctly curved and dilated, less so at the extremity ; tarsi 

 moderately thick. 



This must be ])laced after L. insolitus (36G8) and L. ililutipes (3780), 

 in both of which the elytral suture is thickened and somewhat elevated, 

 besides differing iji minor details. The present species is differentiated 

 from eveiy other known to me by the pex-uliarly formed posterior tibiae. 



Length, 3.]-3| mm. ; breadth, l.Vmm. 



Moa Basin. Two examples, captured by Mr. T. Hall.
