PSEUDAGENIA. 16$ 



bottom shorter than the third ; the first transverse cubital nervure obliquely curved, 

 the second straight, the third sharply oblique, elbowed at the bottom; the first 

 recurrent nervure is received just beyond the middle, the second beyond the basal 

 third. Legs long, pruinose, the tarsi with a fulvous pile ; the long spur of the hind 

 tibiae does not reach the middle of the metatarsus. 



21. Pseudagenia extrema. (Tab. X. fig. 15, wing.) 



Long. 6 inillim. tf . 



Hob. Mexico, Sierra de las Aguas Escondidas in Guerrero 9500 feet (H. II. Smith). 



Similar to P. perdita, but easily separated by the second and third cubital cellules at 

 the top being subequal, the top of each, too, not being very much narrower than the 

 bottom, the cellules being thus wider than long ; the first recurrent nervure is received 

 near the apex of the cellule ; the third transverse cubital nervure is curved and not 

 elbowed at the bottom ; the ocelli are more widely apart, and are separated from the 

 eyes by only a little greater distance than they are from each other ; and the wings 

 from the base of the radial cellule are much darker than the basal region. Eyes 

 almost parallel. Clypeus broadly rounded. Occiput slightly concave. Antennae 

 stout, covered with a microscopic pile; the joints not clearly separated. Prothorax 

 large, subquadrate, the sides bluntly rounded, not much narrowed in front. Thorax 

 alutaceous; the median segment minutely rugose, shining, not furrowed down the 

 middle, and with a gradual rounded slope. Meso pleural furrow placed above the 

 middle. The head and thorax bear long fuscous hairs. 



P. levipes is a near ally of this species, but may be known from it by the second 

 transverse cubital cellule being subcorneal, pointing towards the base of the wings, the 

 third nearly quadrate and receiving the recurrent nervure in the middle, &c. 



v 22. Pseudagenia teapae. (Tab. X. fig. 17, wing.) 



Nigra, tibiis tarsisque anticis pallide fuseis ; alis hyalinis, apice fere fumatis. <5 . 

 Long. 6 millim. 



Hah. Mexico, Teapa in Tabasco (II. H. Smith). 



•Head finely and closely punctured ; the face and cheeks from a little above the 

 antennae covered with a dense white pubescence ; eyes curved above, converging a little 

 beneath ; ocelli in a curve, the hinder ones separated from each other by a little less 

 distance than they are from the eyes ; clypeus with the sides oblique, straight, the 

 centre very slightly roundly-concave at the apex ; the occiput slightly concave in the 

 centre; a narrow channel runs down from the ocelli. Prothorax deeply arcuate in 

 front; obliquely narrowed from the tegulae. The thorax above alutaceous, the 

 scutellum and pleurae finely punctured; the scutellum narrowed towards the apex; 

 the median segment sharply oblique to the apex, which again has an oblique slope.
