326 REVISION OF THE CICINDELIDyE OF AUSTRALIA, 



well be recognised, at least till we become acquainted with 

 Hope's typical form. The variety M. nickerli Srnka, from 

 Cooktown, is of a wholly testaceous colour. 



Habits. — Never having taken a species of Megacephala, I have 

 no personal knowledge of their habits; but I am able to give a 

 few notes from the observations of others. 



Mr. Masters informed me that he found M. crucigera Macl., 

 coming out from its diurnal hiding places in the evening, on sand 

 banks along the river Burnett at Gayndah in Queensland. 



The types of M. humeralis Macl., were found by Mr. Masters 

 "in considerable numbers under rubbish in the dry sandy bed of 

 the river Don," near Port Denison;* and Mr. F. P. Dodd wrote 

 to me that he found this species " along salt pans near Towns- 

 ville." 



Mr. C. French writes to me that he has found " Tetracha 

 [australis Chaud.] running about on the margins of salt lakes [in the 

 Mallee District, N.W. Victoria], and that he has been informed 

 that " M. murchisoni Fleut., and other species from Western 

 Australia are found in similar haunts." Mr. C. French, junr., 

 wrote to me that he found M, australis "on the sandhills in the 

 mallee in the hottest part of the day, and under logs on the 

 margins of swamps at Benjeroop near Kerang " [Victoria]; and 

 that he also obtained "two specimens one evening on the edge of 

 Lake Albacutya at a lighted candle placed in the middle of a 

 sheet spread out on the ground, evidently attracted by the light." 

 Mr. H. J. Hillier, when sending a specimen of the larva of M. 

 australis, and the drawings of the larva for Plate xxxi., wrote 

 to Mr. Lea, " I had often noticed small holes a good -|-inch in 

 diameter in places around the beds of (dry) lakes on Cooper's 

 Creek (where I lived for several years); and so I dug down, 

 following some of the holes, and then I found the larva always 

 head upwards in the hole as I have drawn it. The holes were 

 about 2^-3 feet deep. I do not know whether they would go 

 deeper, but these holes were almost down to the level of the
