THE CRANE-FLIES 1021 
Hab. Liperta. 
Holotype, alcoholic 7, Monrovia, July 8, 1926 (J. Bequaert). Allotopotype, ¢, 
July 8, 1926. Paratopotypes, 2 22, July 8, 1926. 
Styringomyia dendroides, new species 
Text. Fig. No. 10, 14 
Male. — Length about 6-6.5 mm.; wing about 3.8-4 mm. 
Female. — Length about 5.5 mm.; wing about 3.6-3.7 mm. 
Described from alcoholic specimens. 
Palpi extensively pale, especially the terminal segment. Antennae with the first scapal seg- 
ment dark beneath, pale dorsally; second segment dark; flagellum chiefly pale. Head pale. 
Pronotum dark, extensively pale medially. Mesonotum chiefly pale yellow, rather delicately 
marked with brown lines; praescutum with the delicate median brown vitta divided behind; scutal 
lobes narrowly ringed with brown; scutellum pale; postnotal mediotergite dark with a pale 
median vitta. Pleura yellow. Legs with the dark femoral rings well-marked but narrow and 
occurring on the upper half only, the entire ventral surface of femora immaculate; tibial rings 
similarly distinct. Wings yellow, with a sparse brown pattern, including spots or seams at r-m; 
fork of M2 and M3; m-cu and the distal end of vein 2nd A; veins yellow, dark in the infuscated 
areas. Venation: Vein 2nd A simple, the cell broad. 
Abdomen yellow, the tergites with geminate brown spots on caudal margin, these somewhat 
more extensive on the subterminal segments; less evident brown lateral lines on segments; hypo- 
pygium pale; sternites immaculate. Male hypopygium (Fig. 10, 74) with the ninth tergite a broad 
simple lobe, the caudal margin narrow and obtuse, densely set with setae. Ninth sternite pale, the 
apex simple, bearing two long setae that are obliquely placed on apex. Basistyle terminating in a 
small acute pale spine, the opposite angle produced into a stout lobe that bears the usual seta, this 
unusually broad and flattened. Dististyle complex, shaped about as in the figure, the innermost arm 
unusually slender and bearing spines and branches along the entire length. Aedeagus appearing 
as two blackened obtuse lobes (not figured). 
Hab. LiBertia. 
Holotype, alcoholic ~, Monrovia, July 8, 1926, at light (J. Bequaert). Allo- 
topotype, 9. Paratopotypes, 2 22. 
By Edwards’ key to the species of Styringomyia (Trans. Ent. Soe. London, 
1914: 210-212; 1914), the present form runs to and beyond couplet 16 which 
includes only Asiatic species. S. dendroides is amply distinct from the regional 
species in the structure of the male hypopygium, especially the dististyle. 
Styringomyia vittata Edwards 
1914. Styringomyia vittata Edwards; Trans. Ent. Soc. London, 1914 : 217-218, figs. 23, 60-63. 
A pair, Firestone Plantation No. 3, right bank of the Du River, Liberia, 
July 26, 1926 (J. Bequaert). This is one of the most common and widely dis- 
tributed species of the genus, ranging from West Africa to Natal.
