ANTHEIBIDAE.

on inner side, middle and hind tibiae with sharp spiniform apical mucro. 

 Pygidium of <$ broad, shghtly narrowing apicad, apical margin subtruncate, 

 appearing incrassate when viewed from the anal side. 

 Length : 1-6 mm. 



Three immature evidently belong to the same species. They differ 

 from the $ in the angle of the pronotum being more produced.

13. Melanopsacus glenis, sp. n. 



Pitchy black, glossy, especially on the elytra, the pubescence consisting of 

 dispersed hairs which are not concentrated into spots. 



A little less than twice as long as broad (7 : 4). Sides of prothorax and 

 elytra somewhat rounded, the insect appearing slightly constricted at the base 

 of the prothorax. Antenna nearly as in Text-fig. 11. Pronotum densely 

 reticulate, but the meshes smaller than in the previous species, and the inter- 

 spaces a little wider ; basal angle very little produced downwards. The serial 

 punctures of the elytra deep, the interstices without granules. Pygidium 

 almost twice as broad as long, nearly evenly rounded and smooth, margins not 

 distinctly elevated. Impunctate space of prosternum below carina small. 

 On abdominal segment 1 a basal row of punctures, on 2nd and 3rd a subbasal 

 and a subapical row. 



Length : 1-6 mm.

14. Scirtetinus pacificus, sp. n. 



The only specimen obtained of this genus differs a little, particularly in 

 the antenna, from the various species of Scirtetinus, Jord., 1914, discovered by 

 Dr. Hugh Scott in the Seychelles, and may ultimately need to be transferred to a 

 new genus. But I prefer to emphasise the relationship rather than the difference. 



Glossy, as in Scirtetinus, carina of pronotum a very short distance from the 

 base, its angle shghtly obtuse, lateral carina extending to near middle. 



Twice as long as broad ; piceous, tibiae, tarsi and base of antenna rufous ; 

 pubescence very sparse. Segment 2 of antenna half the length of 1, elongate- 

 conical, a little longer than 3rd and 4th together and very much thicker, 3rd to
