A curious species, structurally close to subapteruSj but 

 scales not green, elytral setae much less conspicuous (indistinct 

 even from the sides), legs and antennae darker, and prothorax 

 with less rounded sides. On the pronotum three vaguely 

 infuscated lines of scales may be traced in some lights. 



Mylloceeus aberrans, n. sp. 



Reddish-brown ; appendages somewhat paler. Densely 

 clothed with very pale-brown, almost fawn-coloured scales, 

 becoming whitish on under-surface ; with dense, conspicuous, 

 subdepressed, almost golden setae; some conspicuous vibrissae 

 at the position of ocular lobes. 



Head convex at base but flat between eyes; inter-ocular 

 fovea small. Eyes large and subovate, but not very prominent. 

 Rostrum about as long as the basal width, sides feebly 

 decreasing in width to near apex, median carina distinct in 

 front, the sublateral ones scarcely traceable through clothing. 

 Antennae long and thin ; first joint of funicle distinctly 

 longer than second. Prothorax moderately transverse, sides 

 gently rounded, base not much wider than apex, the latter 

 very gently incurved to middle; punctures normally concealed. 

 Elytra much wider than prothorax, sides feebly dilated to 

 beyond the middle; striation distinct, seriate punctures ap- 

 pearing small through clothing. Femora edentate. Length, 

 6 mm.

The prothorax is perceptibly wider at the base than 

 at the apex, but not much so, so that the species should 

 preferably be referred to BB rather than to B of the 1914 

 table. Regarding it as such it would be associated with the 

 species of F, it, from all of which it may be distinguished by 

 the prothoracic vibrissae. The front margin of the prothorax 

 is without ocular lobes, but at their position (of other sub- 

 families) there is on each side some conspicuous (almost 

 golden) vibrissae. The setae of the upper-surface are unusually 

 dense, but are not conspicuously erect or suberect; on the 

 elytra they form two or three irregular rows on each inter- 

 stice. The lower edge of each eye almost touches a glabrous 

 space on the under-surface of the rostrum.
