prothonix sparsely clothed at the sides and glabrous elsewhere; 

 head glabrous, even at the sides. 



Head modeiately transverse; rounded between antennae. Eyes 

 small and moderately prominent. Antennae moderately long and 

 thin; club distinctly four-jointed. Profhorax rather convex, 

 about as long as wide; base bifoveate. Elytra rather wide, at base- 

 distinctly wider than prothorax, and more than twice as wide 

 across middle; sides rather strongly and evenly rounded. Legs 

 long; hind CDxae moderately separated. Length, 1^ mm.

 River (Bi-itisli Museum, t'roni: J. J. Walker). 



Rather close to uiasfersi, but antennae longer and thinner, and 

 prothorax not quite the same. 



At a glance the antennae appear to have the joints of subcon- 

 tinuous width, but the eighth joint, although distinctly narrower 

 than the ninth, is almost twice the width of the seventh; the latter 

 is distinctly, but not much, larger than the sixth. The prothoracic 

 foveae are rather small; from some directions a fairly distinct 

 connecting impression is visible, but from others it appears to be 

 entirely absent. 



Scydmaenus calvicejjs, n.sp. 



Colours and clothing much as in preceding species, except that on 

 the elytra the hairs are slightly shorter. 



Head moderately transverse, flattened and almost straight be- 

 tween antennae. Eyes of moderate size and moderately prominent. 

 Antennae rather short; club conspicuously four-jointed. Frothorary 

 about as long as wide; base with two rather large round foveae, 

 close together, but without a connecting impression. Elytra with 

 outlines much as in preceding species. Metasternum rather con- 

 vex. Legs moderately long; hind coxae closer together than usuaU 

 although distinctly separated; front tibiae somewhat inflated in 

 male. Length, 1^ mm.

From the many similarly coloured species readily distinguished 

 by the isolation of tlie prothoracic foveae, and the rather sliort an- 

 tennae, with stouter club than usual ; the clothing also is decidedly 

 shorter than usual. From the pale foi-m of gulosus, which has the 

 foveae similarly isolated, the much shorter antennae are sufiicently 

 distinctive. In appearance it is close to mastersi, but is slightly 

 smaller, and antennae shorter, with club decidedly stouter; the 

 prothoracic foveae are also somewhat different. In general ap-
