than to any other species of the genus, the most striking difference 

 in this insect being the abbreviate, rotundate tegmina. 



Little variation is shown by the above series of this very rare 

 insect. In coloration the adults from Augusta and Warm Springs 

 differ from the others in having the median carina of the pronotum 

 outlined in pompeian red. 



This species acts in an unusual manner when pursued, hiding on 

 the underside of the leaves of small plants, with only feet, antennae 

 and eyes showing from above. It was taken among low plants, 

 huckleberry, strawberry and many other varieties, in a sandy scrub- 

 oak area just above the fall line (Augusta), in heavy tangled under- 

 growth of pine and oak woods (Warm Springs), on low open land 

 covered with wire-grass and many low bushes and saw palmettoes 

 on the edge of high bushes and bracken along the border of the 

 Okeefenokee Swamp (Suwannee Creek) and in a very similar situa- 

 tion to the last, where, however, a heather-like plant, Kalmia hirsuta, 

 was predominant (Homer ville). The discovery of this insect just 

 above the fall line at Augusta and on the Piedmont plateau at Warm 

 Springs was rather surprising, as it was hitherto known only from 

 Waycross, Georgia, and Pablo Beach, San Pablo and Hastings, Florida.

Occasional specimens of this species were found from the edge 

 of the pine woods on the upper portion of the lower gradual slopes 

 of Currahee Mountain, to its summit. The specimens were taken 

 in bunch-grass, Cyperus sp., particularly where this was plentiful on 

 open slopes, and in the luxuriant mountain undergrowth of grasses, 

 vines and oak sprouts, under a low forest, predominant in black-jack 

 oak. 



In the southeastern United States this species was previously known 

 only from Sand Mountain, Georgia, and Lookout and Chehawhaw 

 Mountain and its vicinity in Alabama.

It seems impossible to consider this insect other than a western 

 geographic race of H. brevipennis. Material from the type locality. 

 Dallas, Texas, shows hardly any structural differences outside of wing- 

 length, and the present series is nearly intermediate between such 

 specimens and typical brevipennis. Such intermediates were found and
