The type of this species is unique. It is quite singular that the 

 present species shows no close relationship to any of the previously 

 known American forms of this peculiar genus, while its close affinity 

 to the Oriental rugosa is immediately apparent when the two are 

 examined. 



We take pleasure in dedicating this interesting species to the 

 collector, Mr. P. Jorgensen, to whom we are indebted for the oppor- 

 tunity to study the very remarkable collection of Argentine Orthop- 

 fera treated in the present paper. 



Epilampra stigmatiphora- n. sp. 



Type: cf; Misiones, Argentina. February 8, 1910. (P. Jor- 

 gensen; No. 1.) [Acad. Nat. Sci. Phila., tj^pe No. 5,211.] 



This new form is a very interesting species apparently allied to 

 E. testacea Brunner, from Brazil, and caizana Giglio-Tos, from Bolivia, 

 differing from the former in the color pattern of the head and 

 pronotum and in the covered portion of the tegmen being no darker 

 than the general color, and from caizana in the greater size, in the 

 more rotundate median protuberance of the caudal margin of the 

 pronotum, the non-punctate margins of the same, in the blackish 

 humeral trunk of the tegmina and the non-punctate limbs. 



Size medium. Head very slightly projecting beyond the pronotum, 

 considerably depressed; interocular space nearly one and one-half 

 times the depth of the eye, the outline hardly rounded when seen 

 from the dorsum, the eyes well rounded; paired ocelli enormous in 

 size, elliptical in outline, converging ventrad, slightly impressed; 

 antennae slightly longer than half of the body length. Pronotum 

 of the form, found in most species of the genus, cephalic margin 

 regularly arcuate from the lateral angles except for a slight flattening 

 dorsad of the head, lateral angles very narrowly rounded obtuse- 

 angulate, lateral margins moderately convergent caudad, caudal 

 margin appreciably produced mesad into a broad rounded expansion, 

 laterad of which the margins are arcuato-emarginate ; disk with two 

 pairs of impressed punctures slightly cephalad of the middle, the usual 

 transverse creasing of the surface toward the caudal margin distinct 

 but not deep. Tegmina surpassing the apex of the abdomen by 

 about half the pronotal length, moderately broad, the median half 

 subequal in width ; costal margin moderately arcuate in the proximal
