1 6 Cameron, Hymenoptera Orientalia. 



MUTILLA STULTA, sp. nov. 



Long. 8 mm. ?. 



Hab. Trincomali, Ceylon ( Yerbury). 

 In Bingham's Table, {I.e., p. 5) this species comes in at 

 " b\ Spot silvery white, b'^. First abdominal segment not 

 ciliated with white hairs, a^. Second abdominal segment 

 with a transverse band of white pubescence on its apical 

 margin in addition to the spot," but it is very different 

 from M. decora Sm., the representative of this section. 

 With M. trimaculata it has no near relationship; but, 

 judging from the descriptions, it must be nearly related 

 to M. eoronota Bingham. It is not M. stridula Rossi, 

 sec. ^■did. = eoronota Fab., for that has the first segment 

 "arme de dents et carene," which is not the case here; nor 

 has it the pygidial area "ovale, assez grand, finement strie," 

 nor are the tarsi reddish. It is not the eoronota of Saussure, 

 Reise der Novara, Hymen, p. 106, who quotes his Ceylonese 

 species as doubtfully identical with M. eoronota Fab. 

 M. eoronota Sauss. has the pleurae "omnis excavata et 

 polita, postice ad marginem leviter rugulata," while in the 

 present species, the pro- and meta-pleurae, are strongly 

 and coarsely punctured. 



Head wider than the thorax; black, the tubercles and 

 the middle of the mandibles broadly rufous; coarsely 

 punctured, the punctures large and deep; there is a dis- 

 tinct keel down the middle of the front; thickly covered 

 with long, fuscous hair; the tubercles large, shining, im- 

 punctate, a fine keel between them; over them is a 

 moderately thick, curved keel; behind the eyes the head 

 is obliquely narrowed. Antennae stout, the scape shining, 

 sparsely covered with longish, pale hairs; the flagellum 

 opaque, covered with a white down. Thorax distinctly 

 narrower than the head, narrowed towards the base and 

 apex; the pro- and meso-notum coarsely longitudinally
