and distinct maculation of the type, are quite within the range of variation 
in the genus: the maculation where traceable is identical with that of 
levigata and the characteristic t.a. line is distinct in the specimen before 
me. It bears precisely that relation to dewga/a that is borne by mnimalis 
and marcidelinea, to ochreipennis and stands on the same footing as a 
valid species, with the two former. 
Heterogramma palligera, n. sp. Pale clay yellow or Iuteous, 
transverse lines and terminal shade, darker. T.a. line narrow, outwardly curved, 
sinuate, T.p. line narrow, denticulate or crenulate; angulate outwardly on costa, 
thence slightly oblique to the inner margin. A dark transverse shade through the 
median space close to p.t. line. Through the dark terminal space, the pale s.t. line. 
Beneath paler, faintly reproducing maculation of upper side. In the Q the stigmata 
are obsolete; in the J they are distinct, moderate in size, concolorous and broadly 
ringed with darker yellow. 
Expands .80—.go inches, 21—23 mm. Had. Cal. Fla 
Varies considerably in depth of ground color, the males being asa 
rule darker than the females, and the Florida specimens, darker and 
somewhat smaller than those from California. It seems not uncommon 
where found, and flies early, One Florida specimen bearing the date 
March 3. Types §\ and Q in my collection, others in Mr. Hy. Edward's 
(California) and Prof, C. V. Riley’s (Florida) collection. The latter taken 
by Mr. Koebele, 
This insect 1s perfectly congeneric with Didone rurigena. 
Mr. Grote’s genus being synonymous with that of M. Guenee, Fesro- 
gramma must be herafter used for both species.

Hints on Spring Collecting. 
It is at this season that collecting under stones is most profitable. 
Many of the hybernated species are now found, and many species that 
have just left the pupa. Many minute forms also that at other seasons of 
the year are scarce, are now plentiful, if they are but carefully sought. 
When turning stones, do not select only the large ones, and if you see 
nothing under them, drop and leave them; but also take smaller, flat 
stones, pick them up and carefully examine the irregulatities and crevices. 
Many species which escape observation in other ways are thus found. I 
have known a field to be gone over and nothing Lut common stuff found, 
and to be revisited half an hour later and dozens of good species collected, 
The reason was. the last collector was careful and searched closely; the 
first was in a hurry, desired to cover a large territory and found only larger 
and common forms. Cuas, FucHs.
