Bischoff lists this species as one of uncertain generic position. 

 A maie spécimen before us, from Tananarive, Madagascar, présentée! 

 to Cornell University by Mr. Preston Clark, undoubtediy is this 

 species. It belongs to the genus Lophotilla, finding its closest ally 

 apparently in L. lobicornis (André) of which we hâve also seen a 

 spécimen from the same locality. The superior, elevated portion of 

 the clypeus is produced into a strongly elevated, transverse ridge 

 which seen from below is roughly semi-circular in outline; the lower 

 surface of this élévation forms the sloping, upper surface of the disk 

 and is traversed by a curved, transverse row of long, reddish setae; 

 below this the disk of the clypeus is depressed, smooth, and polished; 

 the sides of the clypeus are obscured by vestiture. The sixth sternite 

 has a weakly indicated, latéral tubercle. Seventh sternite with a 

 similar, very small, latéral ridge. The eighth with a weak, transverse, 

 basai ridge and two oblique, strongly elevated tubercles. The seventh 

 and eighth sternites are fused and together are called by André the 

 seventh. 



Lophotilla betsilea (Saussure). 



A maie spécimen before us from Tananarive, Madagascar, pos- 

 sesses felted grooves on both second sternite and tergite. 



Dolichomutilla lessensis, new species. 



Maie. — Black; ground color of the apical abdominal segments red- 

 dish, especially on the venter; calcaria whitish. Spars^ly covered with

 the entire third tergite covered with tomentose, yellow, appressed 

 pubescence; the surface of fourth, fifth, and sixth segments sparsely 

 covered with appressed, yellow pubescence; a very thin fringe of 

 appressed, yellow setae on the apex of the first tergite. Wings deeply 

 infuscated, with violaceous reflection, their bases hyaline, and the 

 apices of the anterior pair broadly hyaline.
