This very (li.stiut't species, which connects //. (i.stitrtc and obliqua with H. Iiijdroiiicli, is easilj'' 

 recognized by its nuiforuily yellow ocherous fore winj;s and body, the fore wings being in the 

 middle quite clear, by the long distinct discal mark and by the l)roa<l diHiusc dark shade behind 

 it, and by the broad white subapicai shade. I copy Harvey's original dcs<'ription of 7/. ccltijiliayu: 



.Smaller thiin //. siibrotala: antenna' pectinate, palpi dependent, tlmkly hirsute; thorax dark a.slicn ; abdomen 

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

 the lines light brown and narrow and similar to 77. subrotata m their conformation; apical white shade not as 

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

 farther removed than in //. siibrutata. Secondaries white, with an incomplete whitish median shade; terminal hue 

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



Expanse, 18 mm. Larva on h.ickberry (Cdtin orchlcntalis). 



The specimen was received from Jlr. C. V. Riley. It is the smallest species of Heterocampa yet known to 

 science. 



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

 The following is a description of Edwards's type specimen: 



It is allied to H. obliqua in general style of markings, bnt has veiy short wings and a square 

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

 wing beliiiid the median vein is a short narrow lilack line, and a very long one starts from its ba.se 

 and f(dlows the base and hind edge of wing, as in H. astarte and obliqua. Beyond this the base and 

 nnddle of the wing is clear tawny ocherous. Discal mark, a ciu'ved 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 inside of the discal spot; in front the blotch 

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

 and the discal si)ot are two parallel lines, the inner black. .V faint linear submarginal scalloped 

 line. Fringe marked with black streaks. 



Hind wings as in If. obliqua var. brnnnea, cloudy on the outer half with a faint jiale band 

 beyond the middle of the wing. l>oth wings clouded lui the under side, becoming darker toward 

 the margin, whitdi suddenly becomes i)ale. 



In comparing, with Dr. Dyar, H. siiperba, subrotata (one loaned by Mr.s. Slos.son), and celtiphafja, 

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

 The specimen of i/. ccltijiliatia hiifi a white spot at the base of the fore wings, and the inner nnugiii 

 is edged with black. The oblitiue subapicai shade is smaller than in subrotata. Mrs. Slosson's 

 S])ecimcn of subrotata differs from the ones I h;ive described in having no ocherous tint, and the 

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

 latter does not present varietal difl'erences from subrotata, being ojily a little smaller (alar expanse, 

 27-2Smm.), while the marks are not so distinct as in the dark uon ocherous exami)le of subrotata 

 in Mrs. Slosson's collection. 



AVe now describe what has been known as //. subrotata: 



Moth.— Own 9 (PI. ^', fig. 17). 



Fore wings short and broad, and rather square at the apex. Body and fore wings uniformly 

 ocherous, collar and teguhe edged with scattered dark scales. Palpi short, small, brown on the outer
