COLEOFTEBA.—LEA. 203 



The black scutellum associates this species in my table with H. gagaticeps, 

 which is a larger species, with two apical joints of antenna? somewhat different; 

 to the preceding species it is closer, but the tenth joint of antennae is different, 

 and the knees are the only pale parts of the legs; the following species has the 

 scutellum and middle tibise pale, and the apical joints are not quite the same. 

 The tenth joint on one side is distinctly incurved, with its tip slightly produced 

 beyond the base of the eleventh ; on one side it is partly excavated for the recep- 

 tion of the base of that joint; the eleventh is slightly wider than the tenth, but 

 from some directions appears to be of the same width. 



HETEROMASTIX MINOR sp. nov. 



(J Black ; prothorax, scutellum, mesosternura, legs (tarsi slightly infus- 

 (;ated), and two basal joints of antennas flavous. With short, ashen pubescence. 



Head with a shallow interocular impression. Antennaj not very long, two 

 apical joints somewhat distorted. Prothorax and elytra as described in H. castor. 

 Length, 3 mm.

The eleventh joint of the antennas is slightly longer than in H. decipiens, 

 and is not quite simple ; the tenth is much shorter, but at first glance the type 

 appears to be a small specimen of that species. It is slightly smaller and with 

 antenna? somewhat similar to those of H. castor and H. pollu.r, but the scutellum 

 is pale ; this character would associate the si^ecies, in my table, with 

 //. palUpes, which has much longer antennse, with the terminal joints different. 

 The tenth joint is somewhat similar to the ninth, but is slightly wider at apex, 

 and a little lopsided ; the eleventh also is lopsided and somewhat dilated at base, 

 but the two joints are so closely applied together that it is difficult to see their 

 junctional parts. 



HETEROMASTIX SCUTELLARIS sp. no^ . 



$ Black; prothorax, scutellum, mentum, mesosternum, legs (tarsi infus- 

 cated), and under surface of three basal joints of antennae flavous. With very 

 short pubescence. 



Head with two faint longitudinal impressions in front, terminating pos- 

 teriorly in two faint interocular ones. Antennas long, two apical joints distorted. 

 ProtJiorax and elytra as described in H. castor. Length {S9 ), 3-75-i-5 mm. 



2 Differs in having the head smaller, with shorter and simple antennae, 

 and abdomen not notched.

The tenth joint of the antennce of the' male is about the length of the 

 ninth, but longer on one side than on the other; the eleventh is constricted
