purplish-blue and scarcely metallic, the flavous sides of . the 

 prothorax wider and sharply defined, the head less shagreened 

 and with more distinct punctures, and the elytral interstices 

 with slightly larger (although still very small) punctures; 

 the seriate punctures, however, have the same waterlogged 

 appearance. 



DiTROPIDUS IMITATOR, U. sp. 



9 • Dark coppery-green and flavous. Under-surface and 

 legs moderately clothed with white pubescence, head more 

 sparsely clothed. 



Bead densely punctate and shagreened; median line 

 moderately distinct. Eyes rather widely separated. 

 Prothorax with dense and sharply denned but not very large 

 punctures on disc, becoming crowded and confluent or 

 substrigose on sides. Elytra with rows of distinct but not 

 very large punctures, becoming larger and set in distinct 

 striae on sides; interstices with sparse and minute punctures. 

 Pygidiinn with a slight median carina. Length, 3'25-3*5 mm. 



//t/V,.— Australia (old collection). Type, I. 10981. 



Allied to, and with outlines as noted for the preceding 

 species, but prothorax entirely dark, and with much denser 

 punctures, becoming still denser and substrigose on the sides; 

 at first glance it appears as if near flavipennis, but the 

 pronotutn is glabrous. The coppery-green parts are the head 

 (a variable amount of the muzzle excepted), prothorax and 

 scutellum ; the elytra are flavous with a slight metallic gloss, 

 but the suture and base are very narrowly dark; the 

 antennae of both specimens under examination are broken, 

 but the basal joints are pale. 



DiTROPIDUS VARIICEPS, U. Sp. 



9 . Red ; part of head, scutellum and most of elytra 

 bronzy with a coppery gloss; club black, parts of tarsi and 

 of abdomen infascated. Head, under-surface, and legs with 

 very short, white pubescence. 



Head rather large ; with sm.all, dense, and frequently 

 obliquely confluent punctures; median line shallow. Mandibles 

 rather large. Eyes widely separated. Prothorax at the base 

 more than twice as wide as the median length; with small 

 and not very dense punctures. Elytra suboblong; with rows 

 of fairly large punctures, becoming smaller but set in deep 

 striae on the sides. Front tihine slightly longer than hind 

 ones. Length, 2'5-2'75 mm.
