HETEROMASTIX PUNCTICORNIS sp. nov. 

 (J Deep black ; head, prothorax, two basal joints of antenna?, and front 

 coxfe bright reddish flavous; front knees feebly diluted with red. With rather 

 dense and short pubescence. 



Head with a faint impression near each eye. Antennse moderately long 

 and rather thin, third to tenth joints each with a puncture on a small polished 

 space near apex on the upper surface. Prothorax about twice as wide as long, 

 margins fairly wide at base and sides, but feeble across apex, sides slightly wider 

 near apex than at base, but not thickened ; with distinct, submarginal punctures. 

 Elytra almost parallel-sided to near apex; with dense and sharply defined 

 punctures of moderate size. Length (c?$ ), 4-4:-5 mm. 



9 Differs in having the head smaller, with less prominent eyes, antennae 

 shorter, without polished punctate spaces, legs shorter, and in the abdomen.

In my table it would be associated with //. geniculatus, from which it 

 differs in being smaller, middle and hind knees and scutellum black, antennae 

 much shorter, &c. ; from H. compar it differs in being more robust, with darker 

 legs and scutellum, antenna? slightly stouter, and many of the joints with a 

 polished punctate space. Structurally it is closest to H. mgripes, and in appear- 

 ance it is much like the female of H. bryanti. The shining spots on the antenna? 

 from some directions look like granules. 



HETEROMASTIX TRICOLOR sp. nov. 



(^ Head, prothorax, scutellum, two basal joints of antennge, parts of palpi 

 and front legs (tarsi and tips of tibine infuscated) flavous; rest of legs, mesoster- 

 num, metasternum, and abdomen black ; elytra deep purple. With rather dense 

 pubescence. 



Head gently convex, with two feeble impressions in front. Antennae 

 moderately long and fairly stout, third joint slightly shorter than fourth, eleventh 

 thinner and conspicuously longer than tenth. Prothorax about twice as wide as 

 long, sides and base with fairly wide margins, front margin very short. Elytra 

 parallel-sided to near apex; with crowded and sharply defined but rather small 

 punctures, becoming smaller at base and apex. Length { S 9), 4-5-6 mm. 



9 Differs in having the head smaller, wdth less prominent eyes, antennae 

 shorter and thinner, and abdomen not notched.
