6 Cameron, Hymenoptera Orientalia. 



at the apex only ; M. atomus has also the head red, and 

 the antennae and thorax entirely ferruginous. 



Antennae stout, the basal three joints ferruginous ; 

 the scape sparsely covered with longish, pale golden hair ; 

 the flagellum with a white, microscopic pile. Head as 

 wide as the thorax ; dark ferruginous, darker on the 

 vertex ; coarsely punctured, sparsely covered with long, 

 pale golden hair ; the third joint of the antennas as long 

 as the following two united. Thorax rounded in front, 

 not much narrowed behind, the sides straight ; above 

 coarsely rugosely reticulated, sparsely covered with long, 

 black hairs. Legs entirely ferruginous-red, covered with 

 long, white hair ; the spurs pale ; the tibial spines stout, 

 reddish. Abdomen black, velvety ; the apex of the basal 

 segment covered rather densely with long, pale golden 

 hair, the second segment broadly at the base, and the third 

 and fourth entirely with golden, depressed pubescence ; 

 the other segments black, and bearing black hairs ; the 

 pygidial area strongly longitudinally striolated. 



The thorax in my only example is somewhat crushed, 

 and I cannot satisfactorily describe its sides; the meso- 

 pleurae appear, however, to be smooth ; the median seg- 

 ment coarsely punctured, and sparsely covered with long, 

 white hair. 



MUTILLA OEDIPUS Cam. 



Col. Bingham (/.<:., p. 27) gives Mutilla cedipus Cam. 

 (he calls it contracta) as the c^ of M. 7'othneyi Cam. 

 There is, however, no evidence, except surmise, that 

 this is the case; and, like so many other species, it 

 had better be kept distinct until direct observation 

 shows what its female really is. Col. Bingham states 

 further that it is not really apterous — that its wings 

 have been torn off. There is nothing novel in the fact of 

 there being an apterous male Mutilla, for there is more
