228 SUPPLEMENT. 



7. Tipula virgulata, sp. n. 



c? . Head reddish-yellow, the upper part of the nasus and the occiput darker, and all greyish-pollinose. First 

 two joints of the antennae yellow, the remaining joints black, the fourth and following joints binodose 

 the distal node longer than the proximal. Mesonotum densely whitish-grey-pollinose ; post-alar callosities 

 yellow ; pleura? yellowish, and all pollinose ; scutellum yellow. Abdomen yellow, opaque, a slender 

 median stripe and the lateral margins black or blackish; the black is more pronounced posteriorly. 

 Hypopygium for the most part light yellow. Legs brownish-red, the tarsi darker, the femora lighter- 

 coloured. Wings greyish and brownish, with a nearly hyaline stripe filling most of the first two basal 

 cells and the first posterior ; the costal cell and narrow clouds bordering the second basal cell brown. 

 Length 18-19 millim. 



Hah. Mexico, Amecameca in Morelos (F. D. Godman). 



One specimen. This species is closely allied to T. virgo, O. S., but differs from it in 

 the colour of the thorax, abdomen, wings, &c. 



PACHYREHINA (p. 15). 



PachyrrMna consularis (p. 17). 



To the localities given, add : — Mexico, Teapa in Tabasco (H. H. Smith). 



A single female specimen from Teapa agrees perfectly with Osten Sacken's description. 

 A female from Rincon, Guerrero (H. H. Smith), has the spots of the vertex a little 

 smaller, the median stripe of the thorax largely yellowish posteriorly, and the black of 

 the abdomen confined to a narrow posterior band on the first, second, third, and fourth 

 segments. 



PachyrrMna ferruginea (p. 18). 



To the localities given, add : — Mexico, Cuernavaca in Morelos, Omilteme in 

 Guerrero (H. II. Smith), Orizaba (H. II. Smith & F. D. Godman). 



Some of the Mexican specimens agree well with Macquart's description of P. quadri- 

 lineata. This species seems to be very variable. 



6. PachyrrMna ? 



S . Head yellow, a minute blackish spot on the vertex. Antennae deep brown, the first three joints yellow. 

 Mesonotum with shining black stripes, the lateral ones incurved and not opaque at the anterior end, tho 

 middle one divided by a yellow stripe. Pleurae yellow, with reddish-yellow spots. Abdomen yellow, 

 with a Bmall brown or black spot on the posterior angle of each segment. Legs yellow ; tip of femora 

 and tibiae, and the tarsi wholly, infuscated or blackish. Wings with a pale yellowish tinge ; stigma 

 lightly infuscated. Length 16-18 millim. 



Hal. Mexico, Orizaba in Guerrero (H. H. Smith). 



A single male specimen. This species is hardly referable to P. affinis> Bell, because 

 of the small frontal spot, the median thoracic stripe, and the markings of the abdomen 

 and legs. A female from the same locality, and undoubtedly belonging to the male, 

 has a series of quadrangular blackish spots on the abdomen. Two other males, from 

 Omilteme, scarcely differ, save in the entire absence of the vertical black spot.
