club. There are, apparently, only five dorsal segments to the 

 hind -body. 



Length, ^ ; breadth, quite i line. 



Maketu, Hunua Eange. One, probably a male. 



Microtyrus. 



Nov. gen. 



Palpi short ; second joint of the maxillary clavate at the ex- 

 tremity, its long basal portion very slender; third very short, thick; 

 fourth largest, nearly securiform-ovate but with the apex acumi- 

 nate, it has a very short basal stalk. Antennce 11-articulate. An- 

 tennal tubercles of only moderate size, with a distinct but rather 

 narrow channel between them. Eyes large and prominent, equally 

 so underneath. Prosternum subcarinate along the middle ; its 

 flanks marked off by a slightly-raised line ; this is oblique in front, 

 but curvate behind, forming an angle near the cox£e. Anterior 

 coxa large, exserted, cylindrical, and contiguous ; the intermediate 

 slightly separated. Mcsostcrrmm with a raised lamina on the middle, 

 its surface flat, both extremities pointed. Metasternum very large, 

 simply convex. Posterior coxce only moderately separated, the tro- 

 chanters prominent. Ahdomcn short, barely as long as the meta- 

 sternum, greatly curvedly narrowed apicallj^, composed of six seg- 

 ments, the fifth with the hind suture incurved, the others with 

 straight sutures, segments 2-5 gradually diminish. Legs long 

 and slender ; tarsi with a small basal joint, the next two joints 

 elongate ; there is but one claw. Ilincl-hody with five visible dorsal 

 segments, the basal three only feebly marginated. 



The genus should be placed near Tyrus, from which it difiers by 

 the structure of the maxillary palpi, by the short and nearly per- 

 pendicular front of the head, by the large metasternum, short abdo- 

 men, &c. 



2461. M. punctatus, n.s. Convex, narrowed anteriorly, pu- 

 bescent, shining, sanguineous ; the legs, antennae, and elytra rufo- 

 fulvous ; palpi and tarsi yellow. 



Head, including the eyes, as broad as the thorax, evidently 

 punctate, without distinct foveas ; when examined from the side a 

 shallow continuous central groove may be seen ; the pubescence is 

 yellow and rather short. Thorax longer than broad, widest near 

 the middle, more narrowed in front than it is behind, punctate ; the 

 broad dorsal furrow extends almost from base to apex, at each side, 

 behind, there is a large elongate fovea, and near the base there is a 

 transverse impression ; it bears some slender hairs. Elytra large, 

 oblong, narrowed near the shoulders, indistinctly punctate ; clothed 

 with bright-yellow hairs, some of these are very short ; the sutural 

 striae are well marked and quite foveiform at the base, the intra- 

 humeral impressions are broad but not very elongate ; they are 

 separated from the shoulders by plicae. Hind-body, as looked at 

 from above, hardly more than half the length of tlie wing-cases, 

 scarcely as broad at the base as these are behind, very much
