This species is very closely allied to Ae. regalis, but has much longer 

 tegmina, is slighter in form, has a less pronounced subapical tubercle 

 to the male abdomen, and differs slightly in color and markings as well 

 as iu the abdominal appendages.

Pezotettix cJienapodii BRUNEB!, Ins. Life, VII (1894), pp. 41-42; Rep. St. Hort. 

 Soc. Xebr., 1894 (1894), p. 163; Bull. Div. Eot. U. S. Dep. Agric., XXXII

Head varying from livid to warm testaceous, faintly, feebly, and 

 sparsely punctate with brown, with mediodorsal and postocular stripes 

 of black as in the neighboring species, the former generally broaden- 

 ing posteriorly and thereafter inclosing a yellow thread; antennae 

 brownish yellow, pallid basally and infuscated apically ; fasti gium more 

 or less shallowly sulcate iu its narrowest part, the frontal costa about 

 as wide as the space between the eyes, equal, nearly fading out before 

 reaching the clypeus, and plane throughout. Pronotura testaceous, 

 sometimes punctate with brown above, with a broad and posteriorly 

 broadening mediodorsal blackish stripe on the prozoua, including a 

 similarly widening testaceous thread or stripe; upper half or rather 

 less of the lateral lobes of the protfona with a similar more or less 

 distinct blackish brown belt, generally accompanied by a testaceous 

 dot at the middle of the upper margin; hinder margin of the pronotuin 

 hardly angulate, but well rounded in a uniform curve; median carina 

 slight on the metazona, wanting or rarely indicated on the prozona. 

 Prosternal spine short, conical, rather blunt. Tegmina subovate, less 

 than twice as long as broad, apically obliquely truncate in the female, 

 not pointed, fuliginous, with crowded brownish and yellowish veins. 

 Hind femora luteo-testaceous, with three broad, transverse angular 

 bands of bluish black, which are but little confluent on the outer 

 face and somewhat less conspicuous on the upper face, the genicular 

 arc black; hind tibiae pale glaucous (sometimes pink, according to 

 Brunei) with the knee and a subbasal annulus pale yellow; the spines 

 black with pallid base. Supraanal plate of male triangular with 

 faintly sinuous sides and roundly pointed apex, the surface flat but 

 with a pair of convergent, rather sharp, but only slightly elevated 

 ridges, inclosing a rather narrow basal longitudinal sulcus, not reach- 

 ing the middle of the plate; there are besides two short, strongly 

 oblique, blunt ridges on the basal half, fading at their extremities; ftir- 

 cula wholly wanting; cerci moderately broad and compressed at base, 

 tapering gradually and regularly over a little more than the basal 

 half, beyond subequal, subcylindrical, but pointed, the apex scarcely 

 incurved and extending scarcely beyond the supraanal plate ; subapical 

 tubercle of subgenital plate small, directed upward and backward, 

 very short and bluntly conical as viewed from behind.
