988 COLEOPTEKA 



Head moderately elongate. Tliorax nearly one-fourth broader 

 than long, more incurved at the base than it is in front ; the sides 

 only moderately rounded, sinuously narrowed behind, posterior 

 angles rectangular, very slightly protuberant ; it is a little convex, 

 the basal fossas are large and situated nearer the sides than the 

 middle ; the discoidal groove is well marked, but does not reach the 

 front margin, near which there is an obsolete curvate impression. 

 Scutellum striate at base. Elytra oblong-oval, humeral angles pro- 

 minent, apical sinuations long but not abrupt ; their striae well 

 marked, the punctures fine but quite distinct though not very close ; 

 interstices a little convex, the third with three or four, the fourth 

 with one (before the middle), and the seventh with about six 

 punctures. 



Only two species of Triclwstcrnus have been found in Otago as 

 yet, T. vircns from Oaniaru is the other ; in it the last abdominal 

 segment of the male has two setigerous punctures on each side of 

 the middle, v/hereas in T. polychcetus there are altogether eight or 

 nine in a row, along the posterior margin : this, of itself, distinguishes 

 ib from the other Trichostcrnl. The femora are stout, the inter- 

 mediate rather abruptly contracted near the extremity.

Pterostichus. 



1776. P. sandageri, n.s. Black ; tibite, tarsi, and antennae 

 nigro-piceous ; labruni and mandibles more rufescent, palpi rufo- 

 piceous ; body oblong, slightly convex, shining. 



Lahrum widely emarginate and setigerous in front. Head large, 

 frontal impressions rather shallow ; eyes prominent. Thorax about 

 one-third broader than long, w'idest near the middle ; the sides 

 moderately rounded, a good deal sinuously narrowed behind, the 

 margins a little reflexed, posterior angles rectangular ; the surface 

 finely transversely lineated, median furrow well marked throughouu ; 

 basal fossae large, united by a large basal depression ; there are also 

 two frontal impressions. Scutelluin striate at base. Elytra rather 

 broader than thorax, very gently rounded laterally, strongly sinuated 

 behind ; basal margins broad, humeral angles prominent ; they are 

 evidently striate, the striae are finely punctured, and each has a 

 short scutellar striola ; interstices a little convex, the third with 

 three, the fifth with two, the seventh with five punctures. Leg^ 

 simple. Terminal ventral segment broadly raised along the sides, 

 and with four apical setigerous punctures. 



This is a large, easily-recognised species, not exactly like any 

 other. It is broader than No. 75 ; the eyes are prominent, but have 

 no general swelling behind them. The presternum is without setas 

 at the tip.
