fact narrowly connected with the apex) the black basal 

 marking on the elytra is completely isolated, as the flavous 

 subbasal part is continued to the extreme margins. On the 

 second form the subbasal flavous part is larger, but is not 

 continued along the suture, and does not touch the sides 

 near the base, although from above it appears to do so. 



Selenurus tenuis, n. sp. 



S ■ Black; elytra with an obscure bluish or greenish 

 gloss ; prothorax flavous, with a small discal infuscation, 

 parts of muzzle and tips of abdominal segments obscurely 

 flavous. Clothed with short, ashen pubescence, and some 

 longer, dark hairs. 



Head rather elongate. Antennae moderately long and 

 thin, third joint about half the length of the fourth. 

 Prothorax subcylindrical, distinctly longer than wide, surface 

 slightly uneven. Elytra slightly wider than prothorax, 

 narrowed posteriorly, terminated long before apex of abdomen ; 

 granulate punctate, or with coarsely rugose punctures. 

 Legs long and thin. Length ( <S , $), 5-6 mm. 



9 • Differs in having somewhat smaller head and 

 shorter legs.

Allied to S. sydneyanus, but prothorax decidedly longer, 

 elytra shorter and more coarsely sculptured, and antennae 

 thicker; the prothorax is much the shape of that of 

 Telephorus kershawi, but that species is without flight 

 wings, whereas on this species they are present. The discal 

 spot is at about the apical third and occupies about one- 

 fourth the length of the prothorax, on one of the males, 

 and on the two females before me; on a second male it is 

 represented by two minute dots. The abdomen is badly 

 shrivelled on all of them. 



Selenurus tenuicornis, n. sp. 



6* . Black ; elytra with an obscure olive-green gloss ; 

 part of muzzle, prothorax (except for a large discal blotch), 

 scutellum, much of sterna, tips of most of the abdominal 

 segments, coxae, basal half of femora, and base of tibiae 

 flavous. With short, ashen pubescence. 



Head rather wide; with large prominent eyes; sides 

 thence strongly narrowed to base; with minute punctures. 

 Antennae long and thin, third joint about half the length 

 of fourth. Prothorax longer than wide, sides almost parallel, 

 apex obtusely produced in middle, disc uneven. Elytra
