106 ENTOMOOLGICAL NEWS. [June, 



However this may be, our specimen is remarkable as an unde- 

 scribed form parasitic on bats, and in spite of differential charac- 

 ters, being probably nearly related to Strebla. As I can find no 

 description of the genus Trichobius, I adopt the name and de- 

 scribe it as new. 



TRICHOBIUS nov. gen. 



Head more or less flattened, tubercular, or warted above; eyes situated 

 nearer the middle than the back of the head, distinct; antennae (?) dis- 

 tinct, apparently single jointed, with a terminal bristle; ocelli absent. 

 Wings present, much longer than the abdomen, with six longitudinal and 

 three transverse veins; first longitudinal vein ending in the front margin 

 at about the outer two-thirds of the wing; second ending a little before 

 the tip; third forking from the second near the base of the wing, and end- 

 ing exactly at the wing tip; anterior transverse vein a little below (behind) 

 the furcation of the second and third veins; the hindmost (innermost) 

 cross-vein, which may be called the posterior, near the margin somewhat 

 below the anterior and between the fifth and sixth veins; the other cross- 

 vein, which may be called the apical, near the margin of the wing and 

 between the fourth and fifth veins. Legs moderately short, somewhat 

 stout; tarsi 5-jointed, the first joint of all pairs not perceptibly longer than 

 each of the three following, very short; claws stout, two-toothed. 



I take pleasure in naming this interesting species in honor of 

 Dr. Alfredo Duges, of the Colegio del Estado, at Guanajnato. 



Trichobius dugesii nov. sp. Entirely tawny, or very pale reddish yellow. 

 Head flattened, warty above, bristly below and at the vertex, rounded in 

 outline, light fulvous; eyes silvery. Thorax deeper fulvous, bristly above; 

 transverse suture distinct, -also dorsal and humeral sutures. Abdomen 

 very light fulvous, somewhat bristly on the sides and at the extremity. 

 Legs fulvous, femora enlarged, very bristly above; last joint of all the 

 tarsi as long as the four very short joints that precede it taken together; 

 claws stout, black, two-toothed; tibiae and tarsi short pubescent. Wings 

 very light fulvous, with veins deeper fulvous; entire wing borders and 

 veins bristly. Length of body, \ 1 /^ mm.; to tips of wings, 2> mm.
