AEPHIA. 127 



Hab. Mexico \ Cordova (Saussure), Eslava (0. W. Barrett), Tlalpam (L. Bruner : 6 ), 

 Coatzacoalcos ( C. C. Beam : $ ). 



There seems to be some little doubt as to the definite determination of several of 

 the above specimens, since they show the apices of the wings more vitreous than 

 Saussure's description would lead us to believe them to be. As will be seen by a 

 reference to the above synoptic table, the two sexes fall into distinct sections. 

 (See also the remarks under the preceding species.) 



12. Arphia calida, sp. n. 



A rather large and robust species, of dark colour, with the median carina of the somewhat tectate pronotum 

 decidedly arcuate, but not greatly elevated. This insect, on account of its bright vermilion wings, at 

 once reminds one of A. pseudonietana, Thom., from which it differs in the much narrower and greatly 

 abbreviated wing-band, and in the more decidedly arched pronotal carina. The female of A. calida 

 is also much more robust, with broader hind femora, as well as being much more strongly granulose 

 on the head and pronotum. In these latter respects A. calida approaches A. conspersa. 1 also 

 occasionally has the dorsal edges of its sparsely mottled tegmina pale testaceous, as in several other 

 species of the genus. 



Length of the body, S 22, $ 31 ; of antennae, 6 7, $ 8 ; of pronotum, c? 6, $ 8 ; of tegmina, 6 23, $ 29 ; 

 of hind femora, S 14, $ 17 millim. 



II ab. Mexico, Zacatecas (L. Bruner). 



The specimens described were found in November.

Hab. X Noeth Ameeica, Colorado 1 2 . — Mexico, Jalisco (Schumann : $ ). 



The collection sent to me contains three specimens of this species, females, one of 

 which bears Saussure's label. While these insects are not at all like any form that 

 occurs in Colorado, they seem to agree well with the description of A. ovaticeps. 

 This inclines the writer to the belief that possibly Saussure erred in assigning his 

 species to Colorado, instead of to Mexico. The hind tibiae of these specimens are 

 dark plumbeous, with a paler basal annulus, while in A. pseudonietana and A. crassa 

 they are brownish or blackish.
