96 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



yellowish) pubescence and not to its shape; the apical spots are 

 also variable; M. communis (I have a specimen from Mr. Cham- 

 pion which was compared with the type) is the form in which 

 the fascia is frequently broken up. (I have specimens under 

 examination which I believe to be this species and in which the 

 median fascia is entirely wanting.) 



Possibly it would be best to regard the species as one having 

 many varieties, including the following : — 



M. communis, Waterh. (type). — Size comparatively small (4^ 

 to 6 mm.), median zigzag fascia seldom complete and usually 

 broken up into small spots and oblique stripes. 



Var. trivialis, Waterh. — Size variable (5 to 8 mm.): prothorax 

 with dense and uniform j^ellowish (or greyish-yellow) pubescence; 

 median zigzag fascia always complete, but more or less variable 

 at suture. 



Var. fugitiva, Lea. — Similar to the preceding, but with the 

 prothoracic pubescence yellowish only at base and apex ; the 

 apical spot on each elytron concave on the side facing the base. 

 Size from 7 to 8 J mm. 



Var. cemula, Lea. — Size comparatively large (7 to 8 mm.); 

 pubescence much as in fugitiva, but the apical spot on each 

 elytron nowhere concave. 



Var. Raymondi, Lea. — Size comparatively small (5 to 6 mm.); 

 the median zigzag fascia complete on the inner but entirely 

 absent on the outer half of the elytra; aculeus and tibial spurs 

 short.

Mr. Blackburn (Trans. Roy. Soc. S.A. 1899, p. 56) remarks on 

 the species of this genus : — " I have not seen (even in some fairly 

 long series) any variation in the colour of the head in any 

 species." I have a female specimen of E. difficilis in which there 

 is a very distinct red fascia near the upper part of the head; on 

 a very careful comparison with typical females, I can find no 

 other differences, even in colour. In another species (possibly
