The female recorded by Rehn from Para, Brazil, as this insect, 

 represents a distinct species, having in that sex transversely truncate 

 tegmina and immaculate tibiae. 



Epilampra berlandi"^ new species. Plate XII, flgiu-es 1 and 2. 



This handsome little insect is one of the smaller species of the 

 genus, showing in the male sex affinity to the larger, but in general 

 similarly colored, males of E. jorgenseni (Rehn)."^ Compared with 

 the male of that species, the present males are found to differ in the 

 decidedly smaller size, wider interocular space, less produced caudal 

 portion of pronotum, less diaphanous tegmina, with much more 

 numerous and smaller maculations and darker wings, with area of 

 costal veins opaque and very dark. Considering the affinity to 

 jorgenseni, we believe that the female of this species will also be 

 found to differ very greatly from the male. 



The size, rather depressed form, grayish coloration and shape 

 and marking of the tegmina give the species a much closer super- 

 ficial resemblance to certain North American species of the Poly- 

 phagid genus Arenivaga than is shown by any of the other known 

 species of Epilampra.

Size rather small, form depressed for the genus. Head very 

 slightly projecting bej^ond the pronotum, considerably depressed; 

 interocular space nearly twice the occipital ocular depth; ocelli very 

 large. Pronotum of the type characteristic for the genus, the sur- 

 face more flattened and production caudad weaker than is usual, 

 agreeing closely with that of jorgenseni except in these respects. 

 Tegmina extending beyond apex of abdomen slightly more than 

 pronotal length, moderately broad, the median half subequal in

11^ A detailed comparison of the type of Rhicnoda jorgenseni Rehn, a female, 

 (described from the Misiones, Argentina, Proc. Acad. Nat. Sci. Phila., 1913, p. 

 277, fig. 1) and males, including the type of Epilampra stigmatiphora Rehn, 

 (described from the Misiones, Argentina, Proc. Acad. Nat. Sci. Phila., 1913, p. 

 279, fig. 2) convinces us that but a single species is represented, of which the 

 sexes are widely dissimilar. The males show no features which would warrant 

 generic separation from the other species of Epilampra. The female, however, is 

 a patelliform type, evidently retaining in the adult numerous features character- 

 istic of the early stages and having tegmina alone represented by small, lateral, 

 triangular pads. As a result the species is recognized as Epilampra jorgenseni 

 (Rehn J, the first species of the genus known to show wide dissimilarity in the sexes.
