Q24 COLEOPTERA 



another, examined from below, this additional segment is as large 

 as the others, with its middle part projecting between the posterior 

 coxae. In E. monticola, E. cereus, and E. incomptus the extra basal 

 dorsal plate is uncovered by the elytra, and bears numerous, ex- 

 cessively minute, brassy scales. In a specimen of E. tuberigerus 

 (see Part in., p. 760, ante) found recently near Howick, the ad- 

 ditional basal segment is wholly exposed above, so that in it 

 seems as if the fourth, and not the third, visible dorsal plate is 

 protuberant at its middle portion. These facts appear to prove con- 

 clusively that the true first segment is retractile.

1656. S. princeps, n.s. Convex, very elongate, medially 

 narrowed, sparsely clothed with sub-erect yellow hairs; shining, 

 piceo-rufous, legs and antennas paler, tarsi and palpi fulvous. 



Head smaller than thorax, oviform; eyes small, antero-lateral. 

 Antenna as long as head and thorax, pilose, their joints elongate ; 

 eighth smallest ; ninth and tenth twice as large as eighth ; eleventh 

 rather larger than tenth. Prothorax longer than broad, widest before 

 the middle, rounded in front, much narrowed posteriorly, with four 

 basal punctures. Elytra elongate-oval, with two indistinct basal 

 impressions, apices rounded. Pygidium sub-conical, marginated, 

 pubescent. Legs long, femora clavate near the extremity, tibiae 

 nearly straight, basal joint of anterior tarsi very slightly thickened. 



Corresponds with the description of S. edwardsi, but the pygidium 

 is not nude, the base of the thorax bears four evident punctures, and 

 an obsolete punctation may be noticed on the wing-cases.

Discovered by Mr. S. W. Fulton, at Taieri, Otago. 



S. galerus, n.s. Elongate, widest behind the middle 

 femora, convex ; shining, infuscate-red, tarsi and palpi fulvous, 

 pubescent. 



Head narrower than thorax, its front part nearly vertical, bearing 

 sub-erect yellow hairs directed backwards ; eyes small, not promi- 

 nent. Antenna inserted in a depression just before the eyes, as long 

 as head and thorax ; five basal articulations cylindrical, second 

 rather longer than the exposed part of the first ; joints 6-10 monili- 

 form, gradually enlarged ; eleventh larger than tenth. Prothorax 

 sub-cordate, longer than broad, widest near the middle, much 

 narrowed behind, posterior angles rectangular, with two basal 



Eunctiform impressions, and a large fovea at each side. Elytra far 

 irger than thorax, considerably narrowed towards the shoulders, 

 depressed at the base, sparingly clothed with pale-yellow hairs 

 much finer than those on the head and thorax. Pygidium but little 

 exposed. Legs elongate, femora inflated near the end, tibiae straight, 

 the inside of the two front pairs ciliated. Palpi with elongate second 

 joint, third elongate and gradually dilated, fourth small but distinct. 

 Differs from S. princeps in size, form, and coloration ; from
