DESCRIPTIONS OF SOME NEW SPECIES OF TABANII).4t. 



BY C. P. WHITNEY, MILKORD, N. H. 



Chrysops lupus, n. sp. — 9 • — Length, 8-9 mm. Face shining yellow- 

 ish ferruginous, callosities outside of suture, and cheeks black. Antennae 

 black, base of first joint fulvous. Front grayish pollinose, callosity black. 

 Thorax black, with the usual glaucous stripes. Scutellum black. 

 Abdomen yellow, first segment with a black spot wider anteriorly, and 

 connecting on second segment with a subquadrate spot deeply emarginate 

 posteriorly, which does not attain the posterior margin of the segment. 

 The following segments have four large triangular black spots anteriorly, 

 well separated from the posterior margins, and forming serrate bands on 

 the fifth and sixth segments. Venter yellow, with transverse black spots 

 increasing posteriorly. Legs black ; front coxae, middle femora and tibiae, 

 distal half of posterior femora, posterior tibise and base of tarsi ferruginous. 



Wings : root, costal cell, crossband and apical spot brown ; first 

 basal cell more than one-half infuscated, second at extreme base only. 

 The crossband reaches the posterior margin only as a brown cloud on the 

 last section of the fifth vein. The apical spot is broad in the distal end of 

 the first submarginal cell and occupies as a brown shade about one-third 

 of the apical part of the second submarginal, being almost disconnected 

 from the crossband by the hyaline triangle which crosses the second 

 longitudinal vein. 



Hab.: Grand Lake, Col. Nine females collected by Mr. G. M. 

 Dodge in»August. Long's Peak, two females, Mr. E. A. Dodge, July. 



The wing picture most resembles hilaris, O. S., of any eastern species, 

 though the first basal cell is farther infuscated. The abdominal markings 

 are somewhat like callidus, O. S., but the spot on second segment is 

 shaped more as on indus, O. S. 



Chrysops Pikei, n. sp. — $ . Length, 6-8 mm. Face yellow, the 

 callosities infuscated outwardly. Antennse slim, first joint yellow, second 

 a little infuscated, the third blackish brown. Front yellow, with black 

 callosity and ocellar space. Thorax black, with wide, well-defined stripes 

 of greenish-yellow. Abdomen yellow, with two broad black median stripes 

 the entire length, and two narrow abbreviated lateral stripes beginning on 

 the third segment. The sixth segment is mostly black. Venter yellow, 

 with slender furcate lateral lines and an abbreviated wider median stripe 

 black. Legs yellow ; distal part of anterior tibiae, anterior and posterior 

 tarsi infuscated.
