1500 COLEOPTEKA 



2584. S. tenebrica, '^-s. Piccous, slightly shining; antonntc 

 ledclish, the apical portion of joints 3-11 usually darker ; femora 

 rufesceni, the middle more or less pitchy; tibiae and tarsi testaceous, 

 the base of the former fuscous. 



Thorax about as long as it is broad, widest near the middle, its 

 sides moderately rounded ; the surface moderately coarsely and 

 closely punctured ; pubescence ash-coloured, scanty and slender. 

 Elytra quite oviform, the middle widest ; the basal margin turned 

 inwards, and somewhat thickened or flattened near the scutellum ; 

 the punctures are moderately coarse and distant, still more distant 

 behind, some nearly reach the apices ; pubescence plender, cinereous 

 aud grey, rather irregularly distributed, the grey most conspicuous, 

 the erect hairs infuscate. Legs with pale-yellow erect hairs ; femora 

 much clavate beyond the middle ; intermediate tibia3 a good deal 

 arched externally, so that the subapical emargination is well marked. 

 Antcmuc with erect yellowish hairs, their third aud fourth joints 

 nearly equal. 



This comes near No. 1053. It has the elytra widest near the 

 hind thighs, they are gradually narrow^ed, not rounded, towards the 

 base ; the greyish pubescence has a blue tinge and covers a large 

 portion of their surface ; the thighs are less clavate ; its tarsi are 

 longer, and the insect itself is larger. 



Male. Second to fourth ventral segments short, fourth incurved 

 behind, fifth reddish, sixth apparently divided along the middle. 



S . Length, If lines ; breadth, f line. 



2 . Length, 2 lines ; breadth, ^ line. 



Maketu, Hunua Eange. Twenty specimens.

2585. S. albicoma, '^-s. Subovate, moderately convex ; 

 cupreo-piceous, a little nitid ; autenna3 infuscate, or reddish, irre- 

 gularly marked with grey ; femora variegate, base and apex reddish ; 

 tibia) and tarsi testaceous, the upper part of the former always dark, 

 sometimes violaceous ; pubescence slender, unevenly distributed, 

 ash-coloured and grey, the latter forming irregular patches on the 

 elytra, their basal portion, however, is usually nearly bare and 

 shining, there are also numerous erect, slender, reddish-brown hairs. 



Thorax about as long as it is broad, widest near the middle, its 

 sides only obtusely rounded ; the surface is moderately coarsely, 

 on the disc not closely, punctured ; sometimes there is a broad, 

 shallow impression near each side behind the middle, the inner 

 borders of these impressions appear to be a little elevated. Elytra 

 of the same width as the thorax at the base, oviform, widest near 

 the middle ; the basal portion with coarse, distant punctures, which 

 are sometimes serial, they become finer and more remote, and seldom 

 altogether disappear, towards the apices ; the basal margin is some- 

 what thickened and flattened towards the suture, and there is, on 

 each elytron, an ill-defined, oblique impression extending backwards. 

 Antcmuc reaching the extremity of the body, with fuscous outstand- 

 ing hairs, their third joint about one-fourth longer than the following 

 one aud extending beyond the base of the thorax.
