maris clypeo antice reflexo leviter emarginato, lateribus 

 pone apicem valde emarginatis, angulis anticis acutis ; 

 tarsis ungaiculisque anticis fortiter incrassatis, his apice 

 abrupte arcuatis ; feminse clypeo antice reflexo vix emar- 

 ginato, lateribus vix sinuatis, angulis anticis subrotun- 

 datis ; an tennis noviesarticulatis. Long., 7-8|- mm. 

 The fringe of erect, moderately close and very long hairs 

 ■completely surrounding the prothorax (the rest of the upper 

 surface being glabrous) gives this insect a peculiar appearance. 

 The hairs along the front of the thorax are evidently darker 

 in colour than those along the base. 



Compared with L. pTioenicopterus, Grerm., the clypeus of the 

 male scarcely differs, while that of the female is less sinuated 

 at the sides ; the head is more closely, the thorax very similarly 

 punctated ; the elytra differ chiefly in being darker along the 

 base and sides, and having the geminate striae more distinct ; 

 ihe pygidium is less closely punctured, and the whole insect is 

 incomparably less hairy. 



The basal joint of the hind tarsi equals about two-thirds of 

 the second joint. 



This species is common on flowers near Tumby Bay in the 

 Port Lincoln district in early summer.

 This species seems to be well distinguished by the strong 

 broad furrow running down the forehead from near the base to 

 the apex, at which point there is in some specimens a minute 

 tubercle on either side. In the specimens which I take to be 

 females the iridescence is conspicuous and brilliant over the 

 whole upper surface, and the puncturation of the pygidium and 

 propygidium is quite rugose ; in a single specimen, which I 

 judge from a slight incrassation of the anterior claws to be the
