336 The Insect Fauna of Van Diemen's Land. 



has a similar number of antennse joints ; its species are 

 mostly of an exceedingly small size^ and are widely distri- 

 buted. Van Diemen's Land has furnished two species 

 described below. 



The family of Endomychida presents a new genus Daulis 

 which is not peculiar to the Fauna of New Holland^ but 

 common also to that of South America. 



The family of the LathridicB have furnished us with two 

 species ; one^ a real Lathridius is new and probably pecu- 

 liar to Van Diemen's Land ; the other is Corticaria gih- 

 bosa, (Latridius gibbosus Hbst. Gyll.) without doubt^ it 

 wandered over originally from Europe. 



In the family of PselapMce, it is interesting to observe 

 how great a similarity exists between the exotic and the 

 indigenous species. The genus Batrisus, whose indigenous 

 species live as guests in the nests of ants^ appears to be the 

 most widely distributed. Some species from the different 

 parts of America and Southern Africa are ah-eady known, 

 and a new species from Van Diemen's Land will be des- 

 cribed below. 



The new species and genera of Tasmanian ColeoptersSj 

 forwarded by Mr. Schayer, are as follows : — 



hasrightly determined its systematic position ; (a .a. o ), but he is not correct in 

 stating ttiat the number of antennae joints is only nine; it has ten like Scymnus, 

 It is with this genus that it presents the greatest similarity, particularly in the larger 

 species.
