MICROCHAETES FASCICULARIS Macl. 



Microchactcs solidus Blackb. 



Tliere was a specimen in tlie Blackburn collection standing under the name 

 of Microchactes solidus. although the type, now in the British Museum, was 

 noted as unique in his collection : hut there was no specimen labelled as Micro- 

 chactcs fascicitlaris. probably indicating that he had discovered that the specimen 

 he former]}' had so named, and Microchaetes solidus, were synonymous, as 

 apjiears to be the case. 



MICROCHAETES MINOR King. 



Mr. B. A. Fcuerheerdt and i ulitained fairlv numerous specimens of this 

 species at Lucindale (South Australia) ; those in ])erfect condition usually have 

 numerous feeble spots of grey or whitish scales on the elytra, and similar scales 

 on the sides of the jjrothorax, on one specimen there are two distinct discal spots 

 on the ])rothorax. King described the tarsi as tctramerous, 1)nt thev are really 

 pentamerous, although it is necessary to examine them under a fairly high power, 

 in a good light, to see the joints clearly; the fourth is small and closely applied 

 to the fifth. 



MICROCHAETES BRYOPHILUS Lea. 



Mr. Carter and I took numerous specimens of this species from moss at 

 Strahan (Tasmania); when the moss was examined over white paper scarcely 

 any were found, but when it was thrown aside the specimens were seen clinging 

 to the paper. 



MICROCHAETES SPHAERICUS Hope. 



Microcliactcs coloratus Blackb., var. 

 Microchactcs ui(jroi<arius Blackb., var. 



Numerous specimens from Lucindale, Mount Lofty, Mount Compass, Port 

 Lincoln, and Kangaroo Island (South Australia), and some cotypes from 

 .Adelaide, appear to indicate that Microchactcs uiijrovarius. as well as Micro- 

 chactcs coloratus, can only be regarded as varietal forms of Microchactes 

 sphacricus; the fascicles vary greatly in number, are frequently numerous, well- 

 delined, and extend to the seventh interstice, or they may be split lip into 

 aliundant Init mostly isolated setae ; or there may be a few fascicles, not extending 

 bevond the fifth or even the third interstice; on the ])ronotum the setae are nearly 

 always isolated, even when abundant, but occasionally there are a few loosely 

 compacted fascicles on it.
