apex, the compressed part is divided into two by a slight ridge, and if 

 seen laterally it looks exactly like a sharp wedge, the last joint is 

 one-third longer than the penultimate, compressed at both ends, but 

 bulging in the centre, roundly elongated at the tip, all the joints are 

 very briefly pubescent and bristly ; prothorax sub-quadrate, narrower 

 behind than in front, truncate in the anterior part, somewhat 

 .arcuate along the base and with both angles rounded, depressed 

 laterally along the outer margins, plane in the disk, and having a 

 distinct median longitudinal impressed line culminating in a trans- 

 verse one in the median part of the base, the surface is extremely 

 finely aciculate and covered with equi-distant, minute, very briefly 

 setigerous granules, divided by an interval slightly wider than their 

 own diameter ; scutellum short, triangular ; elytra broader and a 

 little longer than the prothorax, and also granular, clothed with a 

 flavescent, dense appressed pubescence ; abdomen shiny, the four 

 basal segments impunctate, and the second inermous in the male, the 

 fifth segment is briefly pubescent on the apical part, and the last one 

 somewhat roughly punctate and densely pubescent in the male, 

 equally pubescent but less roughly punctate in the female, underside 

 and legs closely punctate, densely pubescent ; basal joint of hind 

 tarsi very little longer than the second. 



Length 8^9 mm. ; width 24 mm. 



Found in a Termite's nest. 



Hab. Southern Ehodesia (Umtali). A. Bodong. 



Most of the species in which the intermediate antennal joints are 

 shaped as in the present species have been met with in Termites' 

 nests. 



MYRMEDONIA TERMITOPHILA, n. sp. 



Testaceous-red, with the head and clypeus, the elytra, with the 

 exception of the base, and the dorsal part of the three penultimate 

 abdominal segments fuscous, the three basal joints of the antennae 

 are rufescent, the others clothed with a chestnut-brown pubescence ; 

 head quadrate, sparsely punctulate, each puncture bearing a very 

 minute hair, there is a very conspicuous tubercle between the two 

 antennal basal joints, which are very long and swollen at tip, the 

 second is short, the third long, slender at the base, triangularly 

 dilated at the tip, the fourth to tenth are sharply conical, longer 

 than broad at apex, except the two penultimate ones, and the last is 

 as long as the two preceding taken together, oblong, but moderately 

 acuminate at the tip, all these joints are compressed in the manner 

 of M. tcrmitobia but less strongly, and more angular outwardly afc
