1. Holopogon pulcher, sp. n. (Tab. V. fig. 18, c? .) 



S . Front opaque yellow ; on the sides with long Mack hairs ; bristles of the ocellar tubercle long and hair-like. 

 Pace opaque, nearly white, the black ground-colour showing through slightly in some reflections ; hair 

 light yellow ; some black bristles above. Antennae black, slender, the second joint swollen distally ; 

 third joint a little longer than the first two together ; style slender, more than one-half the length of the 

 third joint. Mesonotum yellowish-pollinose on the sides, but almost wholly opaque black, the dark coloration 

 apparently formed by three confluent stripes ; hair long and black, the black bristles hair-like ; scutellum 

 subshining, black, with long, black, hair-like bristles on its margin. Pleuree grey-pollinose. Abdomen 

 rather narrow and elongate, gently tapering from the base ; opaque greenish-yellow ; each segment with 

 a large, opaque, triangular black spot, the apex of which reaches nearly to the hind margin ; hair short, 

 erect, everywhere black ; hypopygium shining black, with black hair. Femora shining black ; four 

 anterior tibia? and the first four joints of their tarsi red ; hind tibiae distally, and the hind tarsi largely, 

 black, the basal portion of all red ; bristles long and slender, black. Wings clouded with brownish, 

 darker on the distal part in front. Axillary cell narrow ; alulae rudimentary. Length 8 millim. 



Hob. Mexico, Venta de Zopilote in Guerrero (H. H. Smith). 

 Three specimens. 



2. Holopogon violaceus, sp. n. (Tab. V. fig. 17, 2 .) 



2 . Head, wings, and legs as in H. pulcher, the pubescence of the face a little less abundant and yellower, the 

 hind tibiae and tarsi redder. Mesonotum greyish on the sides, yellowish-pollinose toward the middle, 

 with a geminate brown median stripe, and two subconfluent spots on each side, the latter forming a stripe. 

 Pleurae grey, with a shining vertical spot in the middle. Abdomen somewhat oval (not so narrow as in 

 H. pulcher), shining black, with brilliant violaceous reflections ; all the segments with a triangular, 

 yellowish-grey-pollinose spot on each hind angle ; the hair short, erect, and black, save on the sides of 

 the anterior segments, where it is longer and white. Length 8 millim. 



Hab. Mexico, Venta de Zopilote in Guerrero (H. H. Smith).

3. Holopogon dejectus, sp. n. 



2 . Pront and face broader than in H. violaceus, covered with greyish-yellow dust, somewhat variable on the 

 face, the lower part of the front blackish ; hairs of the ocellar tubercle small and whitish ; black hairs of 

 the sides of the face and front short. First two joints of the antennae of nearly equal length, sub triangular 

 in shape ; third joint one-third or one-half longer than the first two together, narrowly fusiform in shape ; 

 style not divaricate, about half as long as the joint. Mesonotum greyish-pollinose on the sides (discoloured 

 in the middle in the single specimen received) ; bristles distinct, black ; scutellum with two bristles on its 

 margin. Pleurae thinly and uniformly greyish-pollinose. Abdomen elongate-oval, shining black, glabrous ;
