Australian and Tasmanian Malacodermidae. 105 



Calochromus dentipes, n. sp. 



^ . Black ; elytra reddish-testaceous. 



Head highly polished, unarmed, grooved along middle, the groove 

 becoming foveate between eyes. Antennae extending to apex of 

 elytra, joints subcylindrical and rather thin. Prothorax trans- 

 versely suboblong, deeply impressed in middle, the impression 

 slightly vpidening to base, sides deeply impressed at base and apex, 

 the impressions obscurely connected. Scxftellum subquadrate, de- 

 pressed along middle. Elytra rather narrow, each with four 

 distinct costae, of which, however, the 1st (from the suture) is most 

 and the 3rd and 4th least distinct towards the base, interspaces 

 feebly elevated ; densely punctate. Abdomen with penultimate 

 segment widely and rather deeply excised. Anterior femora stout, 

 each armed beneath with a rather strong but obtuse tooth and with 

 a few small granules. 



Length 8-13 mm. 



$ . Differs in being wider, antennae stouter and much shorter, 

 the head not grooved at the base (but the foveate expansion between 

 the antennae present), the prothorax rather wider at the base and 

 the abdomen and femora simple. "" 



Length 9|^ mm.

 Taylor), Wollongong (A. M. Lea). 



In general appearance close to scutellaris, but the head 

 of the male unarmed. From insidiator (also with the 

 head unarmed in the male) its much larger antennae and 

 narrower form will readily distinguish it ; the female in 

 fact is much the build of the male of that species, and has 

 antennae fully as long. 



Calochromus minor, n. sp. 



9 . Black ; elytra reddish-testaceous. 



Head polished, deeply impressed between antennae. Antennae 

 short (not extending to middle of elytra) stout, subcylindrical ; 

 2nd joint almost half the length of 3rd, 10th almost as wide as long. 

 ProtJiorax, scutellum, and ehjtra much as in the preceding species 

 except that the median sulcus of the prothorax is parallel-sided, deep 

 on its basal and shallow on its apical half. 



Length 5-5^ mm.
