in the type is another question but if such is the case its disappearance 

 may be accounted for by atrophy. In any case there is a consider- 

 able error in Enderlein's interpretation of the veins in the radial field 

 of the wing; the vein labelled R^ should, of course, be i?„ the part 

 spoken of as the radial cross-vein is the basal deflection of /?, and the 

 part called R..,^ is R., alone. The wing is shown in fig. 3. taken from 

 Enderlein's original description of the species. 



Tanypremna regina new species. 



Large species, wing of the male, 22 mm. ; wing heavily marked with 

 brown; supernumerary cross-veins in the basal cells of the wing; tibise white 

 at the base. 



Male, length, 28.2 mm. ; wing, 22 mm. ; abdomen, 23.5 mm. 



Fore leg, femur, 12.7 mm. 



Hind leg, femur, 15.7 mm.; tibia, 15. i mm.; metatarsus, 24.8 mm. 



Frontal prolongation of the head very short, the nasus long and slender, 

 dark brown ; sides of the rostrum more yellowish ; palpi dark brownish black. 

 Antennae with the two basal segments light yellow, the flagellum broken. 

 Front light sulphur-yellow ; vertex and occiput dark brown, paler along the 

 inner margin of the eyes and with a narrow median line. 



Pronotum with the scutum narrow and high, projecting dorsad as a sharp 

 collar, the scutum dark brown, remainder o-f the pronotum yellow. Meso- 

 notal praescutum light yellowish brown with four darker brown stripes, the 

 middle pair being longest, narrowed in front and behind, very dark brownish 

 black on the extreme cephalic margin ; lateral stripes shorter, beginning at the 

 pseudosutural foveae and running caudad to the suture, connected with the 

 middle stripes except behind ; scutum and scutellum broken ; postnotum dark 

 brown, more yellowish medially behind. Pleurae yellowish with a green caste, 

 a small o\al brownish black spot behind the head at the end of the pronotal 

 scutum ; a broader dark brown mark running from the base of the wing ven- 

 trad to the base of the mesocoxa whose posterior face it suffuses. Halteres 

 long, slender, green in color. Legs with the coxje light brownish yellow except 

 the dark mark on the mesocoxa described above ; trochanters greenish ; femora 

 brownish yellow, the tip broadly dark brown; tibiae (only the posterior pair 

 remaining) with the extreme base white and having a decided green caste, 

 remainder of the tibiae dark brown ; the first tarsal segment pale, almost 

 whitish, basally soon darkening to a light brown that includes the remainder 

 of the tarsi. Wings subhyaline in the radial and medial cells, cell C brighter, 

 more yellowish, the anal cells greyish brown, a row of brown blotches in cells 

 R and Af, each one surrounding the spur of a cross-vein, there being about 

 five in cell R and three in cell M ; the cord is seamed with darker brown as 

 are also most of the veins and deflections of veins; stigmal spot a little 

 darker brown. Venation as in figure 4 ; the presence of a supernumerary 

 cross-vein in the basal cells is a feature that, in this subfamily of crane- 

 flics, occurs only in the Dolichopezini ; the numerous spurs of cross-veins in 

 the basal cells is a very remarkable feature.
