A New Species of Dolichopus from Texas. 



By CHARLES T. BRUES. 



The genus Dolichopus is very poorly represented in the 

 Texas fauna. In the vicinity of Austin we have taken only 

 two species, one of which is an undescribed form. The other, 



Fore tarsus (r?) Dolichopus sphaeristes. 



D. ramifcr, is very common, and is frequently seen at consid- 

 erable distances from any water, often upon the vegetation of 

 the dry hill-sides. The new species is described below. 



Dolichopus sphaeristes sp. nov. 



Bright green. Antennae, except part of third joint, yellow. Femora 

 yellow. Cilia of inferior orbit pale. Tegular cilia black. Fourth longi- 

 tudinal vein not broken. Hind tibia? and tarsi at base yellow. Fourth 

 and fifth joints of male fore tarsi enlarged, black ; the fifth bilobed and 

 with a large snow-white empodium. 



Male. Length 6 mm. ; of wing 5 mm. Bright coppery green, moder- 

 ately shining. Face rather narrow, ochraceous, much lighter on lower 

 .fourth. Palpi light yellow. Antennae yellow, except a black spot at in- 

 sertion of arista and the infuscated tip of the third joint. Third joint 

 short, oval, obtusely rounded at the tip. Arista black, about one and 

 one-half times the length of the antennae, distinctly pubescent. Vertex 

 shining green. Post-ocular cilia, except three upper ones, pale yellow. 

 Thorax slightly yellowish pollinose in front. Pleurae darker and white 

 pollinose. Coxae pale yellow, except a black stain on middle pair ex- 

 ternally. Anterior ones bare, except for a row of black hairs along the 

 apical external edge. Middle ones sparsely black hairy anteriorly. Ab- 

 domen green at base and coppery posteriori)'. Last segment and hypo- 

 pygium black. Internal appendages of hypopygium pale ferruginous. 

 Lamellae gradually narrowed toward base and obliquely arcuate at apex ; 

 white, narrowly and sharply bordered with black on the apical half ; 

 strongly bristly at apical angle, elsewhere almost devoid of bristles : with 

 a region of black punctures near anterior angle. Legs yellow, except 

 last two joints of anterior tarsi, which are black ; and four posterior tarsi, 

 which are gradually infuscated beyond tip of first joint. Last two joints 

 -of anterior tarsi much enlarged and fringed with black hairs on anterior 

 edge. The fifth slightly bilobed at apex, part of the joint forming a sort 

 of appendage. Empodium very large, snow-white, almost as large as 

 fifth joint. Posterior tibiae greatly thickened, especially near base, as
