CNEMACANTHIDAE. 359 



3797. Diglymma thoracicum sp. nov. 



Elongate, moderately convex and nitid ; piceo-niger, legs and antennae 

 piceo-rufus ; palpi castaneous, all the joints testaceous at the extremity. 



Head, eyes included, only a fifth narrower than the middle of thorax, 

 depressed and with a series of moderate punctures behind the eyes, the 

 vertex minutely, indistinctly, and distantly punctate ; labrum deeply 

 medially emarginate. Thorax elongate, just an eighth broader than long, 

 base and apex truncate, its sides distinctly and evenly marginate, very 

 slightly rounded, more evidently, but not at all abruptly, near the base so 

 that its angles are obsolete ; discal channel apparently entire when ex- 

 amined from above, a httle shallower near the base and apex, with some 

 scattered but not coarse punctures across the base and front, basal fossae 

 deep and elongate. Elytra nearly thrice the length of thorax, a third 

 broader before the middle than it is, gradually but obviously narrowed 

 behind that point, apices not at all broad, lateral margins distinct, rather 

 more so near the curvedly narrowed shoulders ; their striae rather fine 

 yet quite definite nearly to the extremity, they are finely but not closely 

 punctured ; interstices simple, the sides with about 5 coarse setigerous 

 punctures. 



Terminal articulations of maxillary palpi quite elongate-oval, obtuse at 

 the extremity, less slender than those of Sharp's D. ovipenne or D. duhium. 



Antennae pubescent from the 4th joint onwards, extending to the 

 middle of the thorax, joints 5-10 submoniliform. 



After carefully comparing the only available specimen, a female satu- 

 rated with alcohol, with all the types in my collection I failed to find any 

 exactly like it. D. obtusum (1454), D. punctipenne (1768). and others with 

 obtuse or obsolete posterior thoracic angles present more or less distinct 

 disparities. D. basale, and others belonging to the same section, can be 

 readily separated by looking at the hind angles of the thorax. 



Length, 10 mm. ; breadth, 3^ mm. 



Stewart Island. Described from a single female found during the 

 summer of 1913 by Mr. W. Trail. 



Group LiCINIDAE.

p. 16. 



Suboblong, moderately convex, nitid ; black, femora piceous ; tibiae, 

 tarsi, antennae, epistome, and labrum more or less piceo-rufous ; palpi 

 fusco-fulvous. 



Head and eyes as broad as front of thorax, oviform, somewhat uneven, 

 finely obliquely wrinkled and opaque between the eyes. Thorax quite 

 cordate, a third broader than long, its apex widely emarginate, so that 

 the obtuse angles extend forwards beyond it ; the sides with reflexed 

 well-developed margins, evidently rounded as far as the middle, rather 

 deeply sinuate towards the subrectangular and slightly prominent angles, 

 base medially incurved ; its surface somewhat uneven, basal fossae large, 

 situated between the middle and sides, sometimes interruptedly prolonged 

 nearly to the apex, mesial furrow deep, abbreviated iji front. Elytra 

 oblong-oval, thrice the length and nearly double the width of thorax, 

 broader than it is at the base, curvedly narrowed but not siimate pos- 

 teriorly, with broadly rounded apices ; their impunctate striae deep near
