312 SUPPLEMENT. 



brown, not black ; the median stripe is narrow, the spots small. The markings are better indicated than 

 in D. sallcei, but not nearly so well as in the preceding. The palpi are black. Length 20-22 millim. 



Hob. Mexico, Chilpancingo in Guerrero (H. H. Smith). 



Five specimens. 



SAEOPOGON (p. 179). 



% Saropogon pulcherrima, sp. n. (Tab. VI. fig. 3, s .) 



c? $ . Front black, with purple and blue reflections and black hair. Antennae black ; third joint longer than 

 the first two together, not dilated. Pace flat on the upper part, concave, a little prominent below, the 

 oral margin projecting ; thickly clothed with light yellow tomentum and, on the margin, with a thin 

 row of light yellow hair. Occiput deep black, with short black hair ; orbits narrowly silvery. 

 Mesonotum wholly, and uniformly, deep velvety-black. Scutellum like the mesonotum, with a shining 

 purple margin. Pleurae shining below, opaque above. Halteres black. Abdomen brilliant steel-blue 

 throughout, without markings, the sides nearly parallel. Legs light reddish-yellow ; the immediate base 

 of the femora, the tip of the tibia?, and the tarsi, deep black ; hind femora stout, but not incrassate. The 

 body throughout is nearly bare, with the exception of sparse black pile about the head and anterior coxae. 

 Wings brown, darker along the costa. Length 10 millim. 



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



Four specimens. The third joint of the antennae is sometimes in large part red. 



TARACTICUS. 



Taracticus, Loew, Centur. ii. no. 240 (1872) . 



l. Taracticus similis, sp. n. 



c? 2 • Antennae about as long as the width of the head, black ; first joint a little longer than the second ; the 

 third nearly three times the length of the first two joints together, near its distal end with an emargi- 

 nation on the upperside, at the proximal end of which there is a short spine ; beyond this spine the joint 

 is narrower. The prominent ocellar tubercle shining black ; the front, elsewhere, and the face covered 

 with dense light yellow dust, wholly concealing the black ground-colour ; mystax light yellow, not very 

 abundant. Mesonotum with two median stripes, separated by a slender line, and, on each side, with two 

 large rounded spots, partly confluent at the suture, and narrowly separated from the median stripes : in 

 most of the specimens the markings are opaque black, but in one they are deep brown ; the other parts 

 thickly covered with light yellow dust. Pleurae densely pollinose ; on the upper part yellowish, below 

 white. Scutellum flat, lightly wrinkled, but little shining, the margin yellow-pollinose. Abdomen 

 shining, somewhat metallic, black, punctulate, its colour slightly modified, except on the smooth posterior 

 margin of each segment, by shorter, sparse, yellow hairs ; all the segments on the hind angles with a 

 light yellowish opaque spot, reaching narrowly to the front margin at the sides and for a short distance 

 inward along the hind margin. Legs yellowish-red ; front femora along the upper margin, the middle 

 and posterior femora usually for a less extent along the upper border, and the distal joints of the tarsi 

 for a variable extent, black : sometimes the front tibiae along the upper margin and the middle tibia? in 

 part are also black ; structure of the hind legs as in T. octopunctatus, Say. Wings tinged with yellowish ; 

 venation as in T. octopunctatus. Length 10-12 millim. 



Hab. Mexico, Omilteme and Sierra de las Aguas Escondidas in Guerrero 8000- 

 9000 feet (H. H. Smith). 



Fifteen specimens. The extent of the black of the legs is variable. The species is 

 closely allied to T. octopunctatus. Say, but differs in the structure of the antennae and 

 in the markings of the mesonotum.
