Male genital segment moderately large; claspers slender, flat- 

 tened a little distad, with a second smaller pair between them; 

 latter more slender, shorter, flattened at apex; anal valve broad, 

 large, somewhat longer than claspers. 



Described from 1 male from Los Banos, P. I. {Baker) . 



This is apparently very closely related to Epipsylla albolineata 

 Kuwayama ^ from Formosa. The chief differences between the 

 two species are : the two additional pairs of stripes in pulchra, 

 size of vertex and cones, color of wings and male genitalia; 

 only one pair of claspers is mentioned for E. albolineata. 



Euphalerus nigrivittatus sp. nov. (Plate I, figs. F, L.) 



Length of body, 2.8 mm.; length of forewing, 3 mm.; width 

 of head with eyes, 1.1 mm. General color whitish, with a black 

 vitta on each side of body extending from tip of cone along 

 side of same over eye and side of thorax, the two vittse uniting 

 on mesonotum and extending on dorsum of abdomen; vitta 

 continued along posterior margin of forewing around apical mar- 

 gin ; anterior and mid tarsi black. Surface of body finely retic- 

 ulated. 



Head about as broad as thorax, continuing descending plane 

 of notum, with cones about as long as broad between eyes, with 

 a small foveal impression on each side of median line near center; 

 cones broader than long, not deflexed nor depressed below plane 

 of vertex, almost contiguous on inner margin, rather square on 

 apical margin, pubescent. Antennae about as long as body, 

 slender. 



Thorax broad, robust, somewhat arched. Propleurites rather 

 narrow, partially concealed by the large eyes. Forewings large, 

 hyaline, about half as broad as long, slightly rhomboidal, veins 

 setigerous; marginal cells long; pterostigma very small; black 

 stripe narrow on posterior margin, broader on apical and ex- 

 tending into radial cell. 



Abdomen large. Female genital segment about half as long 

 as rest of abdomen, rather thick, ventral plate slightly shorter 

 than dorsal. 



Described from 1 female from Los Banos, P. I. {Baker) . 



This bears some resemblance to an Indian species of this same 

 genus, E. vittatus Crawford,* but is much larger and diflters in 

 several characters, such as shape of forewing, antennae, and 

 sculpturing of vertex.
