 The whole joint has not the least resemblance to a helmet 

 as may be noticed in gagatice])s. 



Heteromastix laticollis, n. sp. {Figs. 34, 38.) 



(J . Blackish ; prothorax and scutellum flavous ; front coxae and 

 all the trochanters almost flavous. 



Head wide. Antennae long and stout, 2nd joint much smaller 

 than usual, 10th and 11th distorted. Prothorax almost thrice as 

 wide as long, sides almost regularly rounded but slightly thickened 

 in front, base gently sinuous. Mytra rugosely sculptured, slightly 

 dilated posteriorly. Penultimate segment of abdomen semicircularly 

 excised. 



Length 5 mm. 



5 . Differs in having the prothorax wider and antennae and 

 abdomen simple.

The 11th joint is more strongly curved than in the 

 other species ; at its base on one side it is grooved, with 

 part of the 10th joint (which is also peculiarly distorted) 

 resting in the groove ; from another direction the two 

 joints appear very different. The prothorax is wider than 

 in any other species here recorded. The elytra though 

 very densely are not distinctly punctate, and appear to be 

 covered with small and very irregular granules, somewhat 

 after the style of TelepJiorus noHlitatus, etc., there are also 

 on them traces of feeble raised lines, which are also broken 

 up into indistinct granules. In the pair before me the 

 male is the larger. 



Heteromastix decipiens, n. sp. {Fig. 39.) 



$. Black ; prothorax, front legs (tarsi excepted) apex of hind 

 femora, base of hind tibiae and two basal joints of antennae flavous. 



Head convex and smooth. Antennae rather long, 10th joint 

 slightly produced at one side of apex but not distorted ; 11th almost 

 as long as the three preceding combined, distinctly constricted at 

 about two-fifths from its apex. Prothorax almost twice as wide as 

 long, sides regularly rounded. Elytra densely but not coarsely or 

 rugosely punctate. Penultimate segment of abdomen with an almost 

 parallel-sided incision to extreme base. 



Length 5 mm.
