CRAMBINAE. 
Thaumatopsis fieldella sp. nov. 
$. Antennae unipectinate; palpi, head and thorax light brown; 
primaries light ochreous suffused and sprinkled with smoky brown 
which at times is so extended as to render the whole wing almost 
unicolorous brown; basal half of costa rather broadly deep brown; a 
streak of the same color extends from the middle of the cell to the 
apex of the wing, heaviest and most prominent in the cell, where it 
is slightly shaded inferiorly with paler ochreous than the ground color 
of wing; beyond the cell the streak is diffuse and less distinct; from 
the end of the cell to the middle of inner margin an indistinct oblique 
brown line, only noticeable in the paler specimens; a distinct brown 
submarginal line outcurved below costa, with slight inward angle on 
vein Cu’, minutely crenulate, shaded outwardly with pale ochreous, 
terminal row of minute black dots; fringes dusky. Secondaries smoky, 
paler at base and outer margin, with a faint dark, irregular, subterm- 
inal line. Beneath smoky brown, paler along inner margin of sec- 
ondaries, costa of primaries at times slightly tinged towards apex with 
ochreous. 
9. Antennae simple; paler in color than ¢, rather bright ochreous- 
yellow without much dark shading; basal half of costa not shaded 
with brown; subterminal line orange-yellow; dark streak in cell as in 
6; secondaries whitish. Beneath primaries pale smoky, secondaries 
whitish. Expanse ¢ 25-31 mm., 2 31 mm. 
Habitat :—San Diego, Calif. (G. H. Field) (June 6 & 16; 
July 17 & 27; Aug.6 & 15).58 6,12. 
In the dark forms the subterminal line and the streak in the 
cell are the most persistent of the markings.

(Plate XII) 
Entomological workers who have occasion to refer in more 
or less detail to the relation of mosquitoes to malaria usually 
find that students have difficulty in grasping the essential fea- 
tures of the complicated life-cycle of the malarial parasite. 
Taking the suggestion from Maxwell-Lefroy’s diagram pub- 
lished in his manual of “Indian Insect Life,” I have attempted
