Species of Nciv- Zealand Goleoptera, 315 



iti form and coloration, presents some important differences. 

 The eyes are obviously larger and much more convex, so that 

 the head seems different in form. The antennfE are inserted 

 very close to the front of the eyes, and their basal articulation 

 is much stouter. In A. sculpticoUis the fourth joint of tlie 

 anterior tarsi is excavate at the front face, in this species the 

 excavation is less circular and extends a little further back.

Manavvatu Flats, nine miles below the Gorge. 



One, amongst other beetles collected by Mr. W. W. 

 Smith and Mr. Frank Park. 



Group Anchomenidae. 

 Dicrochile tlioracica, sp. n. 



Subdejjressed, head and thorax glossy black, elytra less 

 shining, legs piceous, palpi, antennse, and tarsi rufescent. 



Head broadly oval, rather narrower than thorax, uneven ; 

 the groove between the eye and antenna rather broad and 

 deep, there is a slight longitudinal groove on the vertex, and 

 some distinct oblique ruga? and two foveiform impressions 

 between the eyes. Thorax 2^ mm. long and broad, widest 

 before the middle, gently rounded towards the prominent 

 but obtuse anterior angles, its sides nearly straight yet 

 gradually narrowed backwards, posterior angles obliquely 

 rounded ; base slightly, the apex deeply, incurved ; lateral 

 margins reddish, reflexed, more strongly behind ; median 

 furrow well marked, at each side a broad depression extends 

 towards the middle, the base is minutely wrndcled, there are 

 several abbreviated striae before the oblique frontal im- 

 pressions, and the disk itself is faintly transversely striate. 

 Elytra oblong-oval, obliquely sinuate posteriorly, apices 

 obtusely rounded ; their striae are distinct and regular but 

 quite impunctate, scutellar striae very distinctly impressed, 

 interstices almost flat, the third with two small punctures. 



The nearest ally is D. subopaca, in 1). t/ioracica, however, 

 the thorax is relatively longer and narrower, more deeply 

 cmarginate in front, the anterior angles though obtuse are 

 more prominent, the elytra are longer and appear narrower, 

 w iiilst the scutellar stria? are broader and deeper.
