Tlie immature examples of this insect are as handsome as the 

 adults, but very different in color and color pattern (see plate IV, 

 fig. 17). These arc solidly black dorsad with a very narrow medio- 

 longitudinal buffy line and the lateral margins more broadly of the 

 same coloration. The antennae are black, with a broad medio- 

 proximal and broader medio-distal annulus of white. The cerci 

 are black, fading proximad and distad to buffy. 



When we consider that the very complex color pattern of the 

 adult appears only after the last moult, it is surprising to find it as 

 extremely constant as is shown by this and other considerable 

 series of the species at hand. 



In the adult condition the maxillary palpi arc always whitish, 

 never showing darker markings or suffusions. 

 Euphyllodromia decastigmata'i^ new species (Plate IV, figures 18 to 20.) 



The present species shows nearest relationship to E. angustata 

 (Latreille), differing in its slightly smaller size, absence of a medio- 

 longitudinal jjale line on the pronotum, distinctly shorter tegmina, 

 differently marked mesonotimi and metanotum and distinctive 

 styles of the male subgenital j^late, which are much more elongate 

 and produced than in any other sjiccics of the gentis known to us.

Size small for the genus, form and \er\- delicate structure normal. Head with 

 interocular space (.35 millimeter) about one-third width between antennal sockets. 

 Ocellar sjjots small and weakly defined. Maxillary palpi with fourth joint approxi- 



"- In allusion to the ten pale markings found on the pronotum.
