ISCHNOGNATHA. 
Ischnognatha, Felder, Reise Nov. Lep. t. 102. f. 2. 
This genus appears to be close to Automolis. 
1. Ischnognatha godmani, sp.n. (Tab. IX. fig. 1.) 
Primaries with the basal two thirds brownish black, all the veins and the apical third pale yellow; secon- 
daries pale yellow, the costal margin narrowly banded with black, the inner and outer margin broadly 
banded with black: the head and front ‘of the thorax bright yellow, striped with brownish black; 
thorax brown; tegule brown and yellow; antenne black; palpi pale yellow; abdomen black on the 
upperside, also the anal segments; the sides and under surface pale yellow; legs yellow and black. 
Expanse 2 inches. 
Hab. Panama, Bugaba (Champion). 
Sphinx rutilus of Cramer is allied to this species, and will come into this genus. 
2. Ischnognatha semiopalina. 
Ischnognatha semiopalina, Feld. Reise Nov. Lep. t. 102. f. 2°. 
Trichromia semiopalina, Boisd. Lép. Guat. p. 99°. 
Hab. Nicaraaua?.—Britiso Guiana?. 
My only authority for including this species in our fauna is Boisduval’s, who states 
that he received a single example from Nicaragua. 
CRATOPLASTIS. 
Cratoplastis, Felder, Reise Nov. Lep. t. 102. f. 8. 
1. Cratoplastis diluta. 
Cratoplastis diluta, Felder, Reise Nov. Lep. t. 102°. f£. 8; Butl. Journ. Linn. Soc., Zool. xii. p. 430. 
Hab. Panama, Bugaba (Champion).— Amazons (Bates) ’. 
A single specimen of this curious species was obtained. 
PIONIA. 
Pionia, Walker, Cat. i. p. 255. 
This genus was founded by Walker for the reception of an insect from Venezuela. 
Central America appears to be the head quarters of this genus, eight species occurring 
in our district, six of which are now described for the first time. 
1. Pionia lycoides. 
Pionia lycoides, Walk. Cat. i. p. 2567; Butl. Ill. Lep. Het. i. t. 8. f. 107, 
Hab. Britisn Honpuras, Rio Sarstoon (Blancaneaux); Panama, Bugaba (Champion). 
—VeENEZUELA (Dyson) 1; Ecuapor (mus. D.); Sours-nast Brazi ?. 
In our country this species appears to be scarce. From Ecuador I have a good 
series of specimens, which do not differ in any respect from those from Central 
America.
