The two species found byMr. F. W. Urich in Trinidad can 

 be described as follows : 



Embia urichi, n. sp. 



Rather large for the genus, of a brown colour, with the 

 anterior part of the head more testaceous, eyes small, slightly 

 prominent ; seen from the side, narrowly reniform, more distant 

 on the vertex one from the other than the antenna?. 



Antenna?, long, brown, formed of 21 joints, of which the 

 second very short, the third longer than the following joints, the 

 last three or four luteous white, the last with a black dot, all very 

 hairy. Legs rather stout, principally the hind femora. The 

 anterior metatarsus much swelled. 



Male — Head more elongate, occiput being somewhat 

 lengthened. Antennae as long as the thorax. Pronotum with 

 a strong ridge in front, wings transparent blackish with fuscous 

 veins and with five white longitudinal lines between the 

 veins. The medial vein (sector) bifurcate in the middle ; its 

 posterior branch itself bifurcate ; the 2 ulnar (posterior) veins 

 distinct and of a brown colour. Some scattered transverse venulse 

 in all parts of the wing, abdomen slender, slightly dilated at its 

 end. Supra-anal plate broadly triangular with its angle obtuse. 

 Appendages (cerci) brown, rather long, compressed ; their second 

 joints somewhat longer than the first, but variable, sometimes 

 cylindrical and slender. The infra-anal plate broadly triangular 

 or slightly asymetric. The titillatores not prominent. — Length 

 11 mill., wings 10 mill. 



Female — Completely apterous, head a little shorter than in 

 the male, the whole body covered with scattered hair ; antenna? 

 shorter than in the males, shorter than the thorax, with shorter 

 joints, sometimes rufous. Pronatum marked with 2 transverse 

 ridges. Mesonotum quadrate, elongate. Metanotum transverse 

 quadrate. First abdominal segment rather broad, with the 

 epimeri produced laterally, yellow ; the following epimeri of the 

 same yellow colour. The 5th, 6th segments somewhat narrower, the 

 7th, 9th somewhat broader again. The supra anal plate triangular, 

 somewhat rounded. The appendages cylindrical, but sometimes 

 compressed, legs somewhat thicker than in the males often of a 

 pale colour. — Length 17 mill. 



Embia trinitatis, n. sp. 



Rather small, of a brownish black colour, eyes largeal, 

 prominent, seen from the side broadly reniform ; on the vertex 

 more approximate than the antenna?. Antenna? formed of 21 to 

 22 joints, all brown. 



Male — Head stouter than in E. urichi. The occiput 

 somewhat shorter. Pronotum brick-red, or orange-red, wings
