M. Lacordairc places it, although witli some (loiil)t. Tlu' suh- 

 fimiily forms to a certain extent an exception to the cognate 

 groups in regard to the tarsi, the pubescence beneath being 

 " very coarse, sometimes almost spinous ;" in Ectyche it is 

 completely setose (or sjnnous). The Ampliidorinae hitherto 

 have been exclusively Californian and Cliilian ; and, notwitli- 

 standing there are so many points of agreement between the 

 latter and tlie Australian beetle-faunas, it was not until after 

 a long examination that I ventured to consider tliis genus one 

 of its members. All the essential characters, however, are 

 the same, the intercoxal process, very broad in Ami^liidora it- 

 self, is considerably less so in Stenotrichus] and we have seen 

 that the vestiture of the tarsi is variable. 



I owe my specimen to the Rev. George Bostock, of Free- 

 mantle. 



Ectyche erehea. PI. XI. fig. 1. 



E. oblonga, nigra, opaca ; elytris striato-punctatis, interstitiis crebre 

 punctatis. 



Hah. Freemantle. 



Black, opaque, everywhere above covered with long, erect, 

 slender, black hairs ; head, upper lip, and prothorax closely 

 and finely punctured ] scutellum minute, punctiform ; elytra 

 about three times the length of the prothorax, striate-punctate, 

 the intervals closely and rugosely punctured ; breast gla- 

 brous, closely punctured ; abdomen coarsely punctured, hairy. 

 Length 2 lines. 



The following species is closely allied to Ectyche^ but differs 

 in the character of the tibiae, which are all of the same form and 

 toothed (or rather, perhaps, shortly spined) externally. It is a 

 much smaller species ; and my specimen, which I owe to ^Ir. 

 Odewahn, of Gawler, having been carded, the gum (?) used has 

 such a tenacious property that it is impossible to get rid of it so 

 as to be able to examine the different organs satisfactorily. I 

 record it here principally to call the attention of Australian 

 entomologists to the subject. The occurrence of two such 

 closely allied species so far apart suggests the probability that 

 these are by no means such isolated forms as they now appear 

 to be. It is not unlikely that they are ants'-nest insects.

 Sliortly ovate, opaque black, but tlio elytra slightly glossy.
