Hah. North America \ Texas (Scudder), Carrizo Springs, San Antonio (coll. 

 L. Bruner). 



While no Mexican specimens or records of this species are at hand, its occurrence 

 to the south and west of the Rio Grande is quite certain. Saussure did not know it, 

 as is shown by the labelling of the insect here described as A. difficilis (see antea, 

 p. 124). 



25. Arphia decepta, sp. n. 



Arphia behrensi, Sauss. Prodr. (Edip. p. 71 (1884) (in part.) \ 



A medium-sized, broad- winged species, with a very conspicuous carina running over the occiput and continuing 

 to the front end of the scutellum of the vertex, and the disc of the pronotum coarsely granulated. 



Scutellum of the vertex moderately deep, about as long as broad ( $ ), or a little broader than long ( $ ), the 

 bounding carinse in advance of the transverse groove straight, meeting in front at about a right angle ( $ ), 

 or at a somewhat acute angle ( <$ ) ; lateral foveola? rather large and quadrate, their inner side shortest, 

 the bounding-walls prominent ; frontal costa moderately broad, shallowly sulcate, and continuous to the 

 clypeus. Pronotum rather deep and of moderate length, its sides compressed, the lateral carinse well- 

 defined, nearly straight, and reaching in advance of the principal sulcus, the latter severing the fairly 

 straight and rather prominent median carina a little in advance of its middle ; anterior margin of the 

 disc somewhat advanced upon the occiput, either rounded or gently angulate, the hind edge about a right 

 angle ( d 1 ) or somewhat obtuse ( $ ). Tegmina and wings of normal length, but perhaps a little broader 

 than usual. Hind femora moderately long and coarse, but not greatly inflated, reaching ( $ ), or 

 extending considerably beyond ( $ ), the tip of the abdomen. 



General colour dark greyish-brown, profusely mottled with darker brown and black, the disc and sides of the 

 pronotum, together with the cheeks, sometimes largely lighter coloured. Wings with the disc some 

 shade of ochraceous or straw-yellow, the fuliginous band of the same pattern as that in A. luteola and 

 A. simplex, but varying from it, as found in those species, as indicated in the table. Hind femora 

 distinctly and broadly banded, both internally and externally ; hind tibiae more or less infuscated apically, 

 near the middle, and at the base, the intermediate portions being pale testaceous or greenish-blue, thus 

 giving these limbs a banded appearance. Sides of the abdomen, especially near its base, darkened. 



Length of body, 6 23, $ 30 ; of pronotum, <$ 5-60, $ 7 ; of tegmina, 6 24-25, $ 28 ; of hind femora, 

 d 13-5, 2 18millim. 



Hah. Mexico, Cordova (Edge : c? $ ), Orizaba (L. Bruner : <$ $ ), San Rafael, Vera 

 Cruz (C. H. T. Townsend: 6 ), Jalapa (0. W. Barrett). 



This insect may prove to be the variety c of Saussure's A. behrensi (see Prodr. (Edip. 

 p. 72) ; but, as will be readily seen upon examination of his table, that species typically 

 should have the frontal costa narrowed at its upper extremity. A. decepta is most 

 nearly related to A. simplex, but differs from it in several respects, as shown in the 

 synoptic table.
