M. cephalutes, except that the ahdonien is not at all metallic, 

 and the vcntijil scopa, instead of hciii}^ entirely white, is 

 creani-eolonr, bhick on the last segment and the apex of the 

 l)enultiniate one. It also differs from ce/i/taiuies in the 

 struetun' of the face, which is not descril)cd by Smith. 

 The supraclypeal area presents a large pit or hollow, sur- 

 rounded hy a triangular rim, which is variably but not 

 coarsely punctnred ; the clypeus is smooth and deeply 

 receding, with a strong dentiform median tubercle near the 

 upper end. 



Hindupur, Anantapur District, April 9-14, 1915. 



M. cephaloti's was described from Northern India ; Bing- 

 ham re^jorted it from Dehra Dun and Ahmcdabad. 



Mcgacliile [EumegachUe) ramakrishna, sp. n. 



? . (Type.) — Like M. tritingulifrons, but smaller, length 

 not quite 13 mm. 



Ventral sropa l)lack only at extrene apix, even the base 

 of last segnuMit with pale Iwiir ; sn[)raelypeal b.isin less dis- 

 tinct, wirh large coarse punctures al)out its margin, the area 

 Ijetween it and the clypeus (practically obsolete in trianyuli- 

 J'rons) quite wide, and coarsely punctured, with a median 

 smooth tubercle; clypeus sliort, with the median tubercle 

 not nearly so large as in triaiigu/ijrons ; mandibles with the 

 second tooth, prominent in triaiiyuhfrons, subobsolete. 



(^ . — Length about 8'5 mm. 



Hair of face dense and pure white, but the upper part of 

 the clypeus is closely and minutely punctured, and bare; 

 anterior coxae with short but well-<'evelo])ed spines; anterior 

 tibia? and basitar.-i polished .md dark ia'own on inner side, 

 the basitarsi distinctly hollowed and a little })ruduced at end; 

 end of alidonien bituberculaie, and at the sides subapically 

 are long black hairs.

There are thiee other species i-n the Indian fauna which 

 should be comi)ared with the above two. M. arcuata, Ckll., 

 from Punjab, is similarly formed, and the distinct tubercle 

 on the inner bolder ol tlie miindiblcs is re| resented iu 

 tiluiiyuliferu. In the species just (lescril)ed the hair on the 

 dorsum of thorax is scanty and wholly white, but the thorax 

 of arcuata hiis sparse black hairs above. M. arcuata also 

 lacks the tubercle on clypeus. 



M. lissojjoda, Cam., from Bombay, has the hair of pleura 

 soot-coloured ; in our insects it is thin and white. M. lisso-
