designate as the Berlandi Group, distinguished by their compara- 

 tively graceful structure and strikingly bicolored tegmina.^^ 



The superficial resemblance of this insect to EudromieUa hicolorata 

 Hebard is striking; closer examination, however, showing the great 

 differences between these species. 



Type: cf ; Passa-Quatro, Rio Las Piedras, MinasGeraes, Brazil. 

 Elevation 1000 meters. [Paris Museum.] 



Size small and form slender for the genus. Eyes large, inter- 

 ocular space nearly two-thirds that between the antennal sockets. 

 Ocellar spots not large but distinct, these and the maxillary palpi 

 much as in berlandi. Pronotum much as in that species, but show^- 

 ing latero-cephalic as well as weaker latero-caudal shallow depres- 

 sions. Tegmina and wings fully developed, extending well beyond 

 cereal apices. Tegmina with (6 and 7) longitudinal discoidal 

 sectors. Wings with clubbed apices of costal veins elongate and 

 heavy, ulnar vein with (5) complete branches, intercalated triangle 

 distinct, width one-half length. Dorsal surface of abdomen un- 

 specialized, latero-caudal angles very bluntly rounded. Supra- 

 anal plate transverse, one-third as long as proximal width, feebly 

 obtuse-angulate produced, but with apex moderately bilobate. 

 Subgenital plate nearly symmetrical;-- lateral portions briefly 

 produced, with straight margins, then suddenly emarginate for 

 an equal distance, forming a projection which is less than rectangul- 

 ate sinistrad, rectangulate dextrad; from these points the plate 

 is again produced and shallowly curled upward, the margins 

 hardly convergent, feebly concave to the broad, transverse apex, 

 the lateral emarginations thus formed being nearly rectangulate 

 and feebly rounded. The lateral portions are thickened and more 

 strongly curled at the latero-caudal angles, thus forming a minute 

 rounded cone, the open base of which is caudad and from within 

 which, springing from its base, on each side, project caudad two 

 minute, strongly curved spines, the apices of which reach the caudal 

 margin. Limb armament, pulvilli, arolia and tarsal claws as given 

 for herlandi. 



Surface shining. Head clay color, the vertex approaching cin- 

 namon-buff, with a very broad interocular band of bister, ocelli 

 buffy, below are three broken bands of bister on the face; the first 

 two each formed by two transverse suffusions which are connected 

 laterad along the antennal sockets, the third formed by four suf- 

 fusions arranged in a line which is strongly convex ventrad. Pro- 

 notum translucent, tinged with cinnamon-buff laterad, with two 

 broad blackish prouts brown longitudinal bands which are separ- 



" From the description of Phyllodromia minor Brunner, it appears probable 

 that that species is either a member of the present group, or of the genus Eudromi- 

 eUa. 



^s The dextral emargination is slightly deeper than the sinistral.
