This very (li.stiuct species, which connects H. astartf and ohliqutt \vith H. hi/dromcU, is easily 

 recognized by its uniformly yellow ocherous fore wings and body, the fore wings being in the 

 middle quite clear, by the long distinct discal mark and by the broad dittuse dark shade behind 

 it, and by the broad white subapical shade. I copy Harvey's original descriptiou of H. celtiphaya: 



Smaller than //. subrotata; antenna' pectinate, palpi dependent, thickly hirsute; thorax dark ashen; abdomen 

 paler, becoming dark ashen toward the tip; primaries dark olivaceous ashen, almost approaching to black. All 

 the lines light brown and narrow and similar to i7. subrotata m their conformation; apical white shade not as 

 extended. Fringes ashen; discal lunate mark brown; from this the scalloped transverse posterior line is externally 

 farther removed than in H. subrotata. Secondaries white, with an incomplete whitish median shade; terminal line 

 black, even ; fringe ashen, pale at base, cut with darker hairs at extremity of the veins. 



Expanse, 18 mm. Larva on hackberry (Cellis occidentalis) . 



The specimen was received from ilr. C. V. Eiley. It is the smallest species of Heteroeampa yet known to 

 science. 



I have examined Edwards's type of H. superha (from Texas) and a male also from Texas. 

 The following is a description of Edward.s's type specimen: 



It is allied to H. ohliqua in general style of markings, but has very short wings and a .square 

 apex. The fore wings are pale tawny ocherous, clearer than in H. astarte. At the base of the 

 wing- behind the median vein is a short narrow black line, and a very long one starts from its base 

 and follows the base and hind edge of wing, as in H. astarte and obliqiia. Beyond this the base and 

 middle of the wing is clear tawny ocherous. Discal mark, a curved black streak, and connected 

 with a long straight black streak in the second median interspace, this line being inclosed in a 

 large black diffuse patch extending below the line and in-side of the discal spot; in front the blotch 

 connects with the submarginal series of black interveiiular straight streaks. Between this series 

 and the discal spot are two parallel lines, the inner black, A faint linear submarginal scalloped 

 line. Fringe marked with black streaks. 



Hind wings as in H. obliqua var. hriinnea, cloud}* on the outer half with a faint pale band 

 beyond the middle of the wing. Both wings clouded on the under side, becoming darker toward 

 the margin, which suddenly becomes pale. 



In comparing, with Dr. Dyar, H. snperha, subrotata (one loaned by Mrs. Slossou), and ceU-iphaf/a, 

 the latter kindly loaned by Mr. Neumoegen, we found that these are nominal species and synonyms. 

 The specimen of H. celtiphaya has a white spot at the base of the fore wings, and the inner margin 

 is edged with black. The oblique subapical shade is smaller than in Kubrotata. Mrs. Slosson's 

 specimen of subrotata differs from the ones I have described in having no ocherous tint, and the 

 black shade under the discal mark is obsolete in both examples of subrotata and ccltipliaiju. The 

 latter does not present varietal differences from subrotata, being only a little smaller (alar expanse, 

 27-28 mm.), while the marks are not so distinct as in the dark non ocherous example of subrotata 

 in Mrs. Slosson's collection. 



We now describe what has been known as H. subrotata: 



Moth.— One 9 (PI. V, fig. 17). 



Fore wings short and bi'oad, and rather square at the apex. Body and fore wings uniformly 

 ocherous, collar and tegulie edged with scattered dark scales. I'alpi short, small, brown on the outer
