This very distinct species, which connects IF. astarte and obliqua with If, hydromeli, is easily 
recognized by its imiforinly yellow ocheroiis fore wings and body, the fore wings being in the 
middle quite clear, by the long distinct discai mark and by the broad dilfnse dark shade behind 
it, and by the broad white subapical shade. I copy Harvey’s original description of H, ceJtiqjJiaga: 
Smaller than II, suhrotata; auteume pectinate, palpi tlcpendent, thickly hirsute; thorax dark ashen; abdomen 
paler, becoinirig dark asheu towai’d the tip; primaries dark olivaceous ashen, almost approaching to black. All 
the lines light brown and narrow ami similar to H. suhroiala in their couformatiou; apical white shade not as 
extended. Fnngos ashen; discai lunate mark brown; from this the Bcalloj)ed transverse posterior line is externally 
farther removed than in IT. snhrotaia. Secondaries white, with an incomplete whitish median shade; terminal line 
black, even ; fringe ashen, [lale at base, cut with darker hairs at extremity of the veins. 
Expanse, 18 mm. Larva on hackherry {Celiis occidentalis). 
The specimen was received from Mr. C. V. Riley. It is the smallest species of Heterocampa yet known to 
science. 
I have examined Edwards’s type of II. sxiperba (from Texas) and a male also from Texas. 
The following is a description of Edwards’s type specimen: 
It is allied to H. ohliqua in general style of markings, but has very sliort wings and a square 
apex. The fore Avings 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 hiiul edge of wing, as in II. astarte and obliqua. Beyond this the base and 
middle of the Aving is clear tawny ocherous. Discai 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 diffiise patch extending below the line and inside of the diseal spot; in front the blotch 
connects with the submarginal series of black intervenular straight streaks. Between this series 
and the discai sjiot are two parallel lines, the inner black. A faint linear submarginal scalloped 
line. Fringe marked Avith black streaks. 
Hind wings as in H. obliqua var. brnnuea.^ cloudy on the outer half with a faint pale band 
beyond the middle of the Aving. Both witigs clouded on the under side, becoming darker toward 
the margin, which suddenly becomes ])ale. 
In comparing, with Dr. Dyar, H. superbay sxibrotata (one loaned by Mrs. Slosson), and celtipliaga.^ 
the latter kindly loaned by ]\Ir. Neuinoegen, we found that these are nominal species and synonyms. 
The specimen of H. celtiphaga has a AAdiite spot at the base of the fore Avings, and the inner margin 
is edged Avith black. The oblique subapical shade is smaller than in suhrotata, Mrs, Slosson’s 
specimen of subrotata differs from the ones I have described in having no ocherous tint, and the 
black shade under the discai mark is obsolete in both examples of sxibrotata and eeltipliaga, Tlie 
latter does not present varietal differences from subrotata.^ being only a little smaller (alar expanse, 
27-28 mm.), Avhile the marks are not so distinct as in the dark non ocherous example of subrotata 
iu Mrs. Slosson’s collection. 
We noAV describe AAdmt has been known as H. suhrotata: 
Moth . — One 9 (PI. Y, fig. 17). 
Fore wings short and broad, and rather square at the apex. Body and fore Avings uniformly 
ocherous, collar and teguhe edged with scattered dark scales. Palpi short, small, brown on the outer
