white and the posterior portion next the lateral carinas sometimes 

 darkened. The tips and outer face of the posterior femora are some- 

 times infuscated and the wliole insect is often more or less blotched 

 with blackish, but never conspicuously so. 



2L:(i,sureinents. — Length, pronotum, male, 8-10 mm., female, 10.5-12; 

 posterior femora, male, 19-22, female, 26-80; ovipositor, 22-30; 

 width, pronotum at widest point, female, G.5-T.5; ovipositor in middle, 

 1.5-1.75. 



Specimens e,iMimined. — Immature specimens of what 1 l)elieve to be 

 this species are in the National Museum from Arizona, Florida, Vir- 

 ginia, and Maryland, and adults from Mar3dand, Virginia, District of 

 Columbia, Mississippi, and Florida. This species has been recorded 

 from New England to Florida and westward to Indiana. 

 It has not been recorded from west of the Mississippi 

 River. In my notebook, however, is mention of a '^'.''.''^^L'f,!',

 On March I, 1904, Dyar took a nearly full-grown male 

 nymph at Jacksonville, Florida, in which the disk of the pronotum has 

 the lateral carinas nearly parallel. It was found in a damp woods and 

 jumped into a pool of water, thus facilitating its capture. I have 

 taken nearly full-grown nymphs in Maryland on Juh' 7, sitting on a 

 low bush at dusk. The young are locally quite common in the vicinity 

 of Washington during April, but the adults are, as a rule, quite rare. 

 The young nymphs have the prosternal spine but little developed. 



Mr. Lutz took a female on Long Island, New York, on October 16, 

 which he considered as approaching quite closely the allied ^1. paehy- 

 7/ien/x^ and questions the distinctness of these two species. But the 

 measurements given in his notes" fall within the range presented by 

 dorsalis.
