sixth strongly, the seventh very strongly dilated, and the^ 

 width of club ; this large and somewhat ovate. Prothorax 

 not much wider than long ; with dense, round, partially-con- 

 cealed punctures. Elytra elongate-cordate ; with rows of 

 rather large and somewhat quadrate or oblong punctures ; 

 interstices densely and rather coarsely punctate, fifth feebly,, 

 the sixth, seventh, eighth, and ninth rather acutely carinate. 

 Ahdnmen with dense punctures; first segment slightly shorter 

 than second and third combined, second slightly shorter than 

 third along middle, but produced at sides, third and fourth 

 combined distinctly longer than fifth. Femora strongly den- 

 tate. Length, 5-5|^ mm. 



TJah. — Victorian Alps (C. French). 



In general appearance not very close to any species of 

 Lyhceha known to me, although it somewhat resembles Melan- 

 terrus ain i>lipennis. The peculiar antennae and abdomen 

 should prevent it from being confused with any other species .- 



LYB.a^BA Blackburni, n. SJD. 



Reddish-brown ; prothorax somewhat darker than elytra. 

 Densely clothed with white scales ; having, on the elytra, a 

 feebly-spotted ajDpearance. 



liostrnm slightly shorter than prothorax, moderately 

 curved, parallel-sided except for a slight dilation at base ; 

 with small punctures in feeble rows behind antennae, almost 

 impunctate elsewhere. First joint of funicle about as long 

 as second and third combined ; second about as long as 

 third and fourth combined. Protliorar not much wider 

 than long ; with dense, round, more or less concealed punc- 

 tures. Eh/fra elongate-cordate ; striate-pimctate, striae rather' 

 narrow, punctures rather large but more or less concealed ; 

 interstices with dense but normally-concealed punctures ; four 

 of the lateral ones acutely carinated. Abdomen with dense 

 puncttxres ; second segment slightly shorter than third and 

 fourth combined. Femora strongly dentate ; tibiae dilated at 

 apex, the four front ones each with a long but not conspicu- 

 ous apical spine. Length, 5 mm. 



Hah. — South Australia: Flinders Peninsiila (T. Black- 

 burn). 



The spine at the apex of each of the four front tibiae 

 commences at the upper portion of the dilated apex, and 

 slightly diverges from the apex itself, which is oblique. Its 

 length is about equal to that of the first tarsal joint, but 

 owing to its position it is apt to be overlooked unless searched 

 for. The only specimen I have seen is probably a female. 



There is another (at present undescribed) South Aus- 

 tralian species in general appearance remarkably close to this;
