is more or less green. Also close to the preceding species, 

 but larger and with eyes almost embedded in head. On the 

 under-surface of the rostrum there is a subconical tubercle, 

 but this may be confined to the male. 



A second specimen, from Roebourne (C. French), has 

 the derm darker and the scales of a rather bright-green, with 

 fairly numerous distinct dark spots on the elytra (on the type 

 the elytra are almost immaculate) and the clothing of the 

 legs almost white. 



Myllocerus confinis, n. sp. 



Black, appendages in places diluted with red. Densely 

 clothed with whitish scales, variegated with numerous small 

 blackish spots on elytra. With numerous short, but distinct, 

 erect or suberect setae on elytra. 



Head gently convex at base, flat and with a narrow 

 fovea between eyes; these large and prominent. Rostrum 

 about as long as the width at base, sides diminishing in width 

 to near apex; median and sublateral carinae distinct. 

 Antennae moderately stout; scape gently curved; first joint 

 of funicle distinctly longer than second. Prothorax at base 

 not twice as wide as the median length, and at apex very 

 little more than the length, apex straight or gently incurved 

 to middle, sides gently rounded and distinctly increasing in 

 width to base; punctures normally traceable. Elytra dis- 

 tinctly, but not much, wider than prothorax; apparently with 

 striae only, but really with fairly large punctures in the striae. 

 Femora scarcely visibly dentate. Length, 5-7 mm.

 datta (Blackburn's collection). Type, I. 2546. 



The six specimens in the Museum evidently belong to but 

 one species, but one has the prothorax almost perfectly straight 

 at apex, one has it moderately incurved to middle (the degree, 

 however, much less than in ooviUi), and the others are inter- 

 mediate between these extremes. The prothorax is consider- 

 ably shorter than in cinerascens and canalicornis , and the hind 

 angles are much more acute. Bilineater has the prothorax 

 conspicuously bivittate. In general appearance it is very 

 close to castor and poUux, and with the base of the prothorax 

 as in the latter species, from which it may be distinguished 

 by the elytral markings being more sharply defined, and the 

 prothoracic markings consisting of a small spot < 19 ) on each 

 side towards the base, instead of rather vague vittae. It is the 

 first of the group with wide base of prothorax to be recorded 

 from South Australia.
