in the bright flavous colour of its elytra, of which less of their tips are black. 

 The tenth joint of the antenna^ of the male is slightly longer than the ninth, and 

 more produced on one side (and curved on it) than on the other; the eleventh 

 is about as long as the ninth and tenth combined, closely applied to the latter 

 and with a narrow notch on one side near the base, the notch invisible from most 

 directions. j\lr. Hacker and I obtained eleven specimens, but only one male. 



HETEROMASTIX CASTOR sp. nov. 

 ^ Black ; prothorax, parts of under surface of head, two basal .joints of 

 antenna', tibige, and parts of femora flavous; tarsi and part of second joint of 

 antenna? infuscated. "With short, ashen pubescence. 



Head with a shallow interocular depression. Antenna^ rather long and 

 .not very thin, tenth and eleventh joints closely applied together. Prothorax 

 about twice as wide as long, sides slightly dilated near apex, but scarcely thickened. 

 Elytra almost parallel-sided to near apex; with dense and small subrugulose 

 punctures. Length, 3-75-4 mm.

The tenth and eleventh joints are somewhat distorted but they are so 

 closely applied together that from some directions they appear to be simple ; the 

 tenth, however, has a slight apical notch, in which is received a basal process 

 from the eleventh ; it is wider than the ninth, slightly longer on one side, and 

 more noticeably on the other ; the eleventh is somewhat dilated at the base, and 

 the process received into the tip of the tenth may be regarded as a remnant of 

 a spine ; its longest side is about twice the length of the tenth. So little of the 

 nmzzle is pale (scarcely more than the labrum) that the species might be regarded 

 as belonging to ee of my table,^ and there associated with H. gagaticcps, which 

 has the apical joints very different ; but, regarding the muzzle as pale, it would 

 be associated with H. imitator, which is a smaller and more fragile species, with 

 thinner antennte, the eleventh joint of which is much thinner than the tenth. 



HETEROMASTIX POLLUX sp. nov. 

 (J Black ; prothorax, two basal joints of antenna?, and knees flavous. With 

 short pubescence. 



Head with two faint interocular impressions. Antennse rather long and 

 not very thin, two apical joints somewhat distorted. Prothorax and elytra as 

 described in preceding species. Length { ^Q), 3-5-4 mm. 



$ Differs in having the head smaller, antenniE shorter, thinner, and 

 simple, and abdomen not notched.
