11. Chrysopila latifrons, sp. n. 



$ . Front as broad as long, opaque yellowish- or greyish-brown ; occiput, and face from below tbe impressed 

 line above the antennse, lighter-coloured, greyish or plumbeous-brown. Antennse deep brown, the basal 

 joints somewhat reddish. Palpi black, proboscis yellowish. Mesonotum dark opaque brown, with the 

 lateral margins and tbree median linear stripes in front lighter-coloured ; covered with light yellow 

 tomentum. Pleura? nearly of the colour of the occiput. Abdomen uniform blackish-brown, a little 

 shining ; tomentum or short hair light yellowish. Legs yellow, the underside of the femora brown, the 

 tarsi distally brown, tomentum of the femora yellowish. Wings nearly hyaline proximally, lightly 

 infuscated distally ; a narrow brown band across the proximal cross-veins and over the tip of the anal 

 cell ; across the outer cross-veins a broad diffuse brownish band, beginning in the small brown stigma ; 

 outer part of the marginal cell more expanded than in 0. plebeia ; anterior branch of the third vein 

 angulated ; contact of the second posterior cell with the discal cell about equal to the length of the 

 posterior cross- vein. Length 7 millim. 



Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 



One specimen. A single female specimen from Atoyac (H. H. Smith) closely 

 resembles the one described, but has the wings hyaline, save for the brown stigma. 



ATHERIX (p. 62). 



2. Atherix latipeimis. 



Atherix latipennis, Bellardi, Saggio etc. ii. p. 93 1 . 



Hab. Mexico, Sierra de las Aguas Escondidas and Omilteme in Guerrero 7000 to 

 8000 feet (H. H. Smith), Angangueo \ Oaxaca 1 . 



Twenty specimens. The males agree with the description ; the females differ very 

 materially in having the wings more largely hyaline, the basal brown spot being much 

 smaller, the legs for the most part yellow, &c. A. latipennis was not identified by 

 Osten Sacken in the earlier part of this work (antea, p. 62). 



3. Atherix concinna, sp. n. (Tab. IV. figg. 23, 23 a, 2 .)

 white-pollinose. Halteres black. Abdomen opaque black, first four segments with a broad, posterior, 

 bluish-white pollinose band, broadly interrupted in the middle ; fifth and sixth segments with the band 

 entire ; hypopygium somewhat reddish. Legs yellow ; middle and hind femora, except the tip, front 

 tibiae and tarsi, the middle tarsi for the most part, and the tip of the hind tarsi, black or blackish. 

 Wings brown, with the following spaces hyaline : the base of the first basal cell, an elongate spot in the 

 anal angle extending into the anal cell, a transverse spot from the marginal cell across the outer part of the 

 first and second basal cells, a narrow band from the fourth vein to the hind margin in the fifth posterior 

 cell, and a narrow band from the costa into the base of the second posterior cell ; a hyaline or subhyaline 

 spot on the costa beyond the tip of the first longitudinal vein ; tip of the wing subhyaline. 



2 . Legs in greater part yellow ; the hind femora yellow, except for a distal brown band, the middle femora 

 black on the basal half. Mesonotum more pollinose than in the male. Hyaline spaces of the wings 

 larger. Length 9-10 millim. 



Bab. Mexico, Acaguizotla and Rincon in Guerrero (H. H. Smith). 

 Three specimens.
