Exallonyx pleuralis new species. (Fig. 15.) 



£. Length 4.8-5.2 mm. Black; tegulae and legs yellow, the anterior 

 coxae blackish at base and the four posterior ones black except at extreme 

 tips ; middle and hind tarsi dark fuscous, except at base ; pedicel of antennae 

 rufous. Head fully twice as wide as long, considerably narrowed behind the 

 eyes; ocelli in an equilateral triangle, the posterior pair closer to one another 

 than to the eye-margin ; seen from the side the eye is removed by its own 

 width from the posterior margin of the head. Malar space less than half the 

 width of the eye, with a deeply impressed furrow. Head not much narrowed 

 below, the clypeus broad, its margin straight or somewhat concave ; front 

 above the antennae with a prominent depression on each side of the intra- 

 antennal carina. Mesonotum sharply narrowed in front, posterior corner of 

 pronotum with a pronouned convex elevation ; no trace of parapsidal fur- 

 rows ; depression at base of scutellum deep. Propodeum coarsely rugose- 

 reticulate, more finely so basally, but without any entirely smooth basal areas ; 

 median carina very indistinctly defined ; in profile the declivity is gradual but 

 rather steep posteriorly. Propleura smooth. Mesopleura with some oblique 

 striae in front of the elevated portion and with a narrow band of longitudinal 

 striae below it ; the punctures along its posterior edge not elongated into striae. 

 Metapleura with a shining space above. Petiole. of abdomen quadrate, with 

 coarse reticulations above and striae beneath ; basal striae on second segment 

 longer than the petiole, of equal length. Legs long and rather slender ; 

 longer spur of posterior tibia nearly half as long as the metatarsus ; tarsal 

 claws of four anterior legs with a long appendage at base. Wings very 

 slightly tinged with brown ; stigma large and broad, radial cell one half as 

 long as the stigma, radial vein meeting the costa at an angle of much more 

 than 45 , second section of radius prolonged downward as a brown streak; 

 discoidal vein, and the cubital less distinctly, indicated as brownish streaks. 



Type and two other specimens from Monroe, Wash., May 20, 

 1908. (A. L. Melander.) 



This nice large species is most easily distinguished from related 

 forms by the sculpture of the mesopleura and the absence of proc- 

 esses on the sixth and seventh flagellar joints. 

 Exallonyx pallidicornis new species. (Fig. 18.) 



c?. Length 2.5-3 mm. Black; legs, including coxae, tegulae, palpi, and 

 base of antennae pale brownish yellow ; hind coxae at base* hind femora above 

 and hind tarsi infuscated ; antennae becoming darker toward apex ; meso- 

 pleura below piceous. Head fully twice as broad as long, ocelli close together 

 in a flattened triangle; posterior pair a little closer one to another than to 

 the eye-margin. Seen from the side the eye is removed by somewhat less 

 than its width from the posterior margin of the head. Malar space barely as 

 long as half the length of the eye, with an indistinct furrow. Head consid- 

 erably narrowed below; clypeus with a concave lower margin. Antennae
