pressed, it is very finely aciculate, sparingly punctulate, and bears 

 a few short hairs ; antennas reaching to about the median part of 

 the elytra ; second joint half the length of the third, fourth to tenth 

 subquadrate being slightly wider than long, well separated from each 

 other, not increasing much in width, eleventh oblong-acuminate, as 

 long as the two preceding taken together, briefly pubescent, and only 

 moderately setulose at -tip ; prothorax as broad as long, slightly 

 sinuate laterally, with the posterior angles rounded, but less broadly 

 than the anterior, very faintly impressed laterally but not along the 

 base, and having a plain median longitudinal line, the surface is 

 very finely aciculate, and bears somewhat remote briefly setigerous 

 punctures ; elytra plainly wider at apex than at base where they are 

 slightly wider than the prothorax at its widest part, very finely 

 aciculate and having also setigerous punctures divided from each 

 other by an interval equal to twice their diameter ; abdominal 

 segments shiny and glabrous on the upper side except the last one 

 which is punctulate and pubescent, the fourth and fifth segments 

 have, however, a double row of four setigerous punctures. 



Length 4-4^ mm. ; width li mm. 



In colour this species resembles M. sinijilcj', but it is smaller, 

 and the shape of the antennal joints differs greatly.

MYRMEDONIA CONSTRITATA, n. sp. 



Female '.' Completely fuscous-black with the exception of the 

 palpi, labrum, the three basal antennal joints and the legs, the other 

 joints of the antenna} are rusty-brown, but the apical joint is 

 flavescent at tip ; and the prothorax has a faint tinge of piceous-red ; 

 longer than the preceding species, but differing in colour only; the 

 shape of the antennal joints is identical, the frontal part has also 

 an anterior tubercle, the sculpture of the prothorax and elytra is 

 the same. 



This may prove to be the female of M. conifcra. 



Length 7 mm. ; width 1^ mm.

MYKMEDONIA ANTHRACINA, (Fauv. in ////.), n. sp.
