94 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



head and elytra dark, another the elytra only, another has the 

 head and sides of elytra dark, another the head and apex of 

 elytra, and another has the entire upper surface pale, except for 

 a cloud on the basal half of the el3^tra. 



HOMOTRYSIS RUFICORNIS, Macl. 



I have a specimen from Somerset, Q , which agrees in all 

 structural details exactly with the type of this species, but its 

 antenn?e (except at the sutures of the basal joints) and legs are 

 entirel}' dark. 



PYTHID^. 



LiSSODRMA HYBRIDUM, Er. 



I have this species from New South Wales, Victoria, and 

 Tasmania. In the last-named State it is exceedingl}^ common, 

 being frequently found under bark, in moss and on fence tops at 

 dusk. In size it varies from H to 2 J mm. The male has a 

 considerably longer prothorax than the female, and has it supplied 

 with a median excavation, which is very distinct when viewed 

 from behind; in the female this is scarcely more than traceable; 

 the male also has the prothorax much narrower posteriorly. I 

 have taken man}^ pairs in copula. 



MELANDRYID^. 

 Mystes planatus, Champ. 

 A specimen (taken whilst struggling in a spider's web just 

 after sundown) from Forest Eeefs. N.S.W., either belongs to or 

 is closely related to this species. It differs from Mr. Champion's 

 description in having the eyes very slightl}^ notched behind the 

 antennaB, and by having four terminal joints of the front, three 

 of the middle and two of the hind tarsi suddenly much paler than 

 the others; the colour of the antennae also diminishes in intensity 

 from base to apex.* 



■•■ This note was sent to Mr, Champion, who wrote me as follows: — "I 

 can hardly say that the eyes are notched in front, though they appear so 

 when the insect is viewed in certain lights. There seems to be a slight 

 depression for the reception of the base of the antennje. As to the colour 

 of the antennge and tarsi, I do not see what you describe, but if present I 

 should not attach any importance to it."
