Nevada. A specimen from British Columbia, sent by Mr. W. H. 

 Harrington, is larger and has the sutures of thorax blackish ; but I 

 can see no structural differences. 



The following nine species have the first abdominal segment 

 shorter and more nearly sessile with the second, thereby approach- 

 ing the species which immediately follow them, differing, however, 

 in that the segment mentioned is considerably contracted anterior 

 to its middle, as in the preceding species of the group. 



132. Mutilla palainedes n. sp. 



%. — Head ami thorax pale castaneous ; abdomen dark -castaueous browu, the 

 first segment paler; legs and antennae testaceons ; head narrowed and rather 

 evenly rounded behind, hardly as wide as thorax; space between hind ocelli 

 about equal to that between them and eyes; antennse scarcely as long as head 

 and thorax, the first joint of flagellum shorter than second, the scape nearly one- 

 third longer than the pedicel and first flagellum joint; reticulation of middle 

 segment tolerably coarse, coarser than in uro, the basal smooth areas scarcely dis- 

 tinquishable from the surrounding reticulation : first abdominal segment rather 

 broad and convex, especially apically, with large, separated punctures: second 

 dorsal very sjjarsely punctured, the punctures of second ventral large and sparse; 

 abdomen without hands of pubescence; wings subhyaline, without fuscous spots, 

 rather strongly iridescent, nervures and stigma testaceous. Length 8 mm.
