Color dark, dull brown with a narrow stripe of fuscous, which is 

 not at all conspicuous on account of the dark ground color, extending 

 from the upper margin of the eye along the lateral lobes of the pro- 

 notum just outside of the lateral carinse. The posterior femora have 

 the outer face marked with three distinct black bands and the knee is 

 black. All these black marks are extended across the ui)per face and 

 upon the inside. The posterior tibiae are bluish. 



Described from a single male from Colorado. 



XIII. AMBLYTROPIDIA, Stal. Fig. 13. 



Vertex extended considerably in front of the eyes, plainly declivent 

 and roundly united with the front from which it is separated by 

 lateral carinae which are almost obsolete or moderately distinct. It is 

 convex and shallowly or scarcely sulcate with a plain median carina. 

 The lateral foveolae are wanting. The frontal costa is plain or sulcate 

 with elevated lateral carinae. The face seen from the side is nearly 

 straight. The antennae are filiform or .slightly enlarged apically and 

 heavy, scarcely as long as the head and pronotum. The pronotum 

 has the disk plain with the carinse, more especially the median, dis- 

 tinct and parallel or the lateral slightly divergent. The median carina 

 is cut near or distinctly behind the middle and the metazone is sharply 

 but very obtusely angulate. The lateral lobes of the pronotum are at 

 least as high as broad with the anterior border moderately oblique, the 

 posterior sub-vertical and the lower a little descending posteriorly, 

 more decidedly ascending anteriorly. The lobes of the mesosternum 

 are separated by a space about as broad as long (male and female) and 

 the metasternal lobes are contiguous behind. The tegmina and wings 

 are well developed with the scapular area of the former not expanded 

 nor hyaline nor regularly veined. The posterior femora are decidedly 

 heavy with the base unusually convex on the outer face. The valves 

 of the ovipositor are exerted.
