tioned by Pascoe), whilst in the present species it is no darker 

 than the rest of the antennae. Its basal joint of tarsi is also 

 slightly longer. It is also close to Joiigicornis, but is larger 

 and paler. 



Belus semipunctatus, Fab. 



? cyanei'pennis, Boh. 

 ? bispinosus, Perr. 



The typical form of this species has somewhat ochreous 

 pubescence only in the subsutural depression and in a line 

 outside of the second carina on each elytron, except for a few 

 feeble spots near the shoulders. 



It seems probable that cyaiieipennis is a synonym of 

 this species, despite several discrepancies in the description. 

 The elytra of semipunctatus are certainly not cyaneous, al- 

 though they usually have a violet or purplish gloss, and 

 the elytra are not "almost three times the length of the pro- 

 thorax," but fully four times the length. The prothorax 

 of one large specimen measures 2^ and the elytra 11 mm. 

 Boheman also makes no mention of the conspicuous elytral 

 costae, but his description is so full and tallies in so many 

 respects with semipi(?ictatics (a quite common species about 

 Sydney) that my surmise will probably prove to be correct. 



It is also possible that bispinosus is a synonym, al- 

 though Perrond describes the prothorax as granulate. In the 

 typical form the prothorax could certainly not fairly be called 

 granulate, although from certain directions certain parts of 

 it appear to be so, owing to the density of the punctures; 

 these, however, are quite clearly defined, and not confluent 

 in most places. In some of the varieties, however, the pro- 

 thorax might almost be called granulate-punctate. 



Variety A. — Two specimens from Mackay differ from the 

 normal form in having two additional rows of spots on each 

 elytron; the extra rows being at the side and between the 

 two carinse. Their derm at the subsutural depression is also 

 largely diluted with red, but this also occurs in forms hav- 

 ing the typical clothing. 



Variety B. — A specimen from Whitton differs from the 

 normal form in being very small (10 mm.) and thin, and with 

 the clothing of an almost snowy whiteness. 



A specimen from Cairns agrees in its clothing with the 

 typical form, but its elytra are of a decided green, without 

 the least trace of violet, and the legs and abdomen are 

 somewhat similarly coloured. The colour, however, may be 

 due to immaturity. Another specimen from Cairns is smaller 

 (11 mm.) than usual, and has the small sublateral spots of 

 the abdomen absent, but this may be due to abrasion.
