PSELAPHIDAE. 487 



Head trigonal, rather short, its hind angles projecting outwardly as far 

 as the widest part of thorax ; frontal channel oblong, deep, extending as 

 far as the middle of the eyes, much narrower between the slightly raised 

 antennal tubercles, occipital foveae rather large. Eyes moderately large 

 and prominent. Thorax cordiform, about as long as broad ; median fovea 

 subrotundate, deep, the lateral ones oviform but not prolonged beyond 

 the middle, the basal pair of punctures small and almost confluent with 

 the median fovea. Elytra oblong, double the length of thorax, nearly 

 twice its breadth, only slightly narrowed near the base, apices truncate, 

 their surface finely and irregularly punctate ; sutural striae well marked, 

 finely punctured near the base, usually with a distinct basal puncture 

 alongside each, the suture minutely punctate, dorsal striae prolonged as 

 far as the middle, composed of two or three impressions, the posterior 

 largest. Hind-body as broad as elytra but shorter, the first visible seg- 

 ment shorter than the following ones, with minute brassy scales. 



Antennae longer than the head and thorax, with slender hairs, basal 

 joint rufous, cylindric, as long as the second and third together, the former 

 oblong-oval, the latter small and moniliform ; joints 5-8 slightly broader 

 and shorter than the oblong-oval fourth and fifth, ninth and tenth more 

 or less transversely quadrate. 



Underside pubescent, finely and indistinctly punctate ; metasternum, 

 and sometimes the abdomen, infuscate. Head with a basal pair of lobes 

 extending forwards, and bearing a yellow fasciculus between and in front 

 of them. Metasternum elongate. Segments 2-4 of abdomen subequal, 

 fifth slightly shorter, sixth short, slightly emarginate, all without impres- 

 sions ; supplementary one broadly triangular, the operculum convex. 



This must be placed in Section III, next to S. genalis (1157), which 

 most nearly resembles it. 



Some specimens though immature and nearly testaceous usually have 

 the metasternum infuscate.

Mounts Dick, Alfred, and Earnslaw, near Lake Wakatipu. About a 

 dozen males found by Mr. T. Hall amongst decayed leaves, at elevations of 

 over 1,000 ft., between the 26th January and the 17th March, 1914, most 

 of them on Mount Dick. 



3994. Sagola tenebrica sp. nov. 



Elongate, interruptedly narrowed anteriorly, shining ; pubescence yellow, 

 elongate and suberect, thicker on the hind-body ; head and thorax rufo- 

 piceous, elytra rufous, abdomen and antennae fusco-rufous, legs and palpi 

 infuscate, tarsi testaceous. 



Head nearly as large as thorax, subtrigonal, but with obtuse hind angles ; 

 frontal channel deep, moderately broad, extending as far as the back of 

 the eyes, considerably narrowed between the nearly flat tubercles, occipital 

 foveae punctiform and distant. Eyes moderate. Thorax rounded and 

 widest before the middle, subcordate ; median fovea subquadrate and 

 uniting with the small basal punctures, lateral foveae deep but not extending 

 forwards to the middle. Elytra a third longer and broader than thorax, 

 gradually narrowed towards the base, nearly plane ; sutural striae deep, 

 simple, the dorsal extend to the middle and consist of a basal puncture and 

 elongate impression. Hind-body slightly broader and a third longer than 

 elytra, nearly horizontal, first segment simple, rather shorter than second, 

 third longer than adjoining ones, fifth small and narrow.
