NO. 1530. THE DECTICIN.E OF NORTH AMERICA— CA UDELL. 345 



Description. — Head, pronotum, abdomen, and wings as in the pre- 

 ceding species except that the posterior margin of the pronotal disk 

 is less rounded than in hruncrl, being sometimes ahnost truncate. Pro- 

 sternal spines variable, sometimes short and blunt and sometimes quite 

 long and sharp. Anterior tibiae armed above on the outer margin 

 onl}' with three spines, \Qvy rarely with four; posterior femora some- 

 what more abruptly swollen basally than in hruneri.^ and the inner carina 

 below is unarmed or armed with but a few very inconspicuous spinules, 

 rarely at all prominent; cerci shaped as in hruneri, those of the male 

 relatively longer, as compared with the basal width (fig. 43). Ovi- 

 positor more slender than in hruneri and generall}^ considerabh' 

 longer, being from about two-thirds as long to fully as long as the pos- 

 terior femora. 



Color as described under the preceding species and similarly variable. 



Measurements. — Length, pronotum, male, 5-6.5 nun., female, 5-7; 

 posterior femora, male, 16-18, female, 15-21; cerci of male, about 1.5; 

 ovipositor, 14-18. 



Ty^^d.— Cat. No. 1106, U. S. National Museum. 



Specimens examined. — Manj^ specimens in various collections from 

 localities from South Dakota through Nebraska, Kansas, and Colorado 

 to New Mexico. A male in the collection of the National Museum is 

 labeled "Florida,'' but very probably erroneously so. 



Superficially this species resembles very closely a species of the 

 genus Eremop)edes." I have taken it on a stony hillside in Colorado, 

 at the base of the mountains, actively hopping about during the middle 

 of the day. They are adepts at eluding capture, their color 

 harmonizing well with that of the surrounding grass and stones. 



The synonymy of minutus and stevensonii seems 

 very certain. The type of stevensoni seems to be 

 lost, but the figure given by Glover shows no 

 specific difl^'erences between that species and 

 minutus. Glover's figure was made soon after 

 the description of stevensoni, and as he always, fic 43.— stipator stevex-

 ings with considera))le certaint}^ His figure 



agrees in size with those given by Thomas, and the original description 

 fails to give any sufiicient character for separating it from mijiutus. 

 A careful examination of the original descriptions of both stevensoni 

 and minutus^ examination of the figures of both species by Glover 

 and a study of the types of minutus and a series of additional speci- 

 mens of that species leads me to the conclusion that there is but one 

 species represented. The type of Briiner's scudderi has been seen and 

 found to belong here.
