having each two rows of four puncture-like pores, one along the 

 suture, the other close to the declivous part of the sides, and 

 two or three scattered punctures on the disk, these punctures are 

 somewhat indistinct ; scutellum very small ; upper side of abdomen 

 glabrous, very finely aciculate, and having on each segment two 

 transverse rows of five broad setigerous punctures, the second 

 segment is not sinuate at apex, and is provided with two sharp 

 incurved spines reaching only the median part of the third segment, 

 the apical segment has two series of elongated tubercles. 



Length 7 mm. ; width li mm. 



Hab. ? Southern Rhodesia. 



This species is easily distinguished by the setigerous pores on the 

 prothorax and on the upper side of the abdomen. 



MYRMEDO:S 7 IA MIMA, 11. Sp. 



Male : Straw-colour, shiny, very briefly pubescent, head darker, 

 frontal part bulging in the anterior part and having a very broad, 

 round depression on the vertex, sparingly punctulate and briefly 

 pubescent ; antennae reaching the apical part of the elytra, second 

 joint two-thirds the length of the third, fourth to tenth nearly as long 

 as broad but in the shape of a broadly truncate cone, and fitting 

 closely to each other, eleventh almost as long as the two taken 

 together, they are briefly pubescent but not setulose at the tip ; pro- 

 thorax slightly broader than long, with the anterior and posterior 

 angles rounded, slightly narrower at the base than at the apex, 

 nearly straight laterally, deeply depressed obliquely along the outer 

 margin, narrowly transversely along the base and having also a 

 broad central impression on the disk, this latter, however, may be 

 accidental, and moderately closely punctulate ; elytra slightly broader 

 than the prothorax at the base, truncate at the apex, the punc- 

 tures are similar to those of the prothorax, and the pubescence is 

 alike ; the first four abdominal segments are glabrous and impunc- 

 tate, and the second simple, the fifth is punctulate laterally and also 

 along the apical margin, and has on each side a longitudinal groove 

 edged by a keel, the last one is pubescent and has an apical impression. 



This species is closely allied to M. longicornis, Boh., described 

 from a female example ; the main difference consists in the shape of 

 the antennal joints, which are much shorter, broader, and closely 

 set ; they resemble more those of M. -prolixa, Boh., which is, how- 

 ever, a different species. 



Length 5 mm. ; width 1J mm.
