Fabricius having placed the Sphex maura eventually in the 

 genus Liris, which contains species all belonging either to 

 Tachytes or Larrada, there can be little doubt of the L. maura 

 of this Catalogue being identical with the Fabrician insect ; it 

 nearly resembles the L. glabrata, but has the metathorax closely 

 and strongly punctured above and behind, the verge of the trun-

 hyaline ; the basal margins of the segments of the abdomen finely 

 punctured, smooth and shining, not pubescent. 



10. Larrada tristis. B.M. 



Female. Length 4 lines. — Black : the face covered with silvery 

 pubescence, the scape rufo-piceous in front. The mesothorax 

 and scutellura very finely and closely punctured, subopake ; the 

 metathorax transversely and somewhat coarsely rugose ; the 

 sides of the disk and the truncation very coarse, and covered with 

 short silvery pubescence ; the sides of the metathorax obliquely 

 striated; wings yellow-hyaline, the nervures and tegulse rufo- 

 testaceous. The abdomen with a fine silky pile ; the margins of 

 the segments with bands of silvery pile, observable in ditferent
