but tlie setiferous ones traceable. Elytra much wider than 

 prothorax, parallel-sided to near apex; striation distinct, 

 seriate punctures moderately large, but appearing small 

 through clothing. Femora lightly dentate. Length, 5-7 mm. 



Hah. — South Australia: Ooldea. Type, I. 7601. 



Twenty-three specimens (including several pairs taken 

 in cop.) are before me, and they appear to belong to but one 

 species, but some specimens have three vaguely infuscated 

 lines on the pronotum, and others are slightly transversely 

 depressed near base and apex, so that (by the 1914 table), the 

 various specimens might be widely separated. The specimens 

 that might be referred to E, of that table, and there associated 

 with multimaculatus, differ from it in being consistently 

 larger, pronotum much wider, head considerably larger and 

 scape much longer and thinner. Those that might be referred 

 to F, i, differ from rugicollis as they differ from multimacii- 

 latus ; from melvillensis they differ in many respects. Those 

 that might be referred to F, n, differ from nasutns in having 

 the eye not quite so long and rather less convex (the distance 

 between the front of an eye and the antennary pit is about 

 once and one-third the length of an eye, in nasutus it is about 

 twice the length of an eye). On the elytra the two colours 

 (of scales) are sometimes very feebly contrasted, the paler 

 scales being in the majority ; but on some males the darker 

 scales are in the majority and sharply contrasted ; on the 

 pronotum there are usually three vaguely infuscated lines. 

 The secondary sexual differences are slight. 



Myllocerus angustipennis, n. sp. 



Piceous-brown ; appendages obscurely diluted with red. 

 Densely clothed with obscurely variegated brownish scales, 

 becoming whitish on sides and under-surf ace ; a row of incon- 

 spicuous setae on each elytral interstice. 



Head moderately convex between eyes, these moderately 

 large but not very prominent. Rostrum distinctly narrowed 

 from base to near apex, median and sublateral carinae narrow 

 and distinct. Antennae long and thin; first joint of funicle 

 much longer than second. Prothorax strongly transverse, 

 sides moderately rounded, base not much wider than apex; 

 punctures normally concealed. Scutellum strongly transverse. 

 Elytra at base scarcely (if at all) wider than base of prothorax, 

 sides feebly dilated to about the middle, and then strongly 

 narrowed to apex; seriate punctures of moderate size, but 

 distinct through clothing, their containing striae very feebly 

 impressed. Femora feebly dentate. Length, 4 \ mm.
