thirds the length ot the tront and distinctly 

 exceeding tlie genae. Genae very strongly 

 incurved below the eyes, making the latter 

 unusually protuberant. Pronotum little 

 longer than vertex, faintly transversely 

 aciculate and with several shallow transverse 

 creases or constrictions. Elytra trapezoidal 

 in outline, reaching the middle of last dorsal 

 segment ; color sordid whitish with numerous 

 fine irregular irrorations, which are more 

 distinct on veins. Fore and middle femora 

 with numerous small white spines. All tibiae 

 more or less marked with dark. 



Last ventral segment a half longer than 

 preceding and with it having a slight median 

 keel ; hind margin truncate with a median 

 notch reaching half the length of the seg- 

 ment. Ovipositor nearly one-third the length 

 of the body and exceeding the pygofers by 

 nearly i inm. 



Length of (J 6 to 8 mm. Much darker 

 than the female, the sternum and most of 

 venter black. In some specimens the upper 

 part of face is shining black. The vertex is 

 shorter and the pronotum less strongly arcu- 

 ated behind. The elytra exceed the abdomen 

 by .5 to .75mm. The plates are long, slender, 

 acutely curved upwards distally, and supplied 

 at base with a slight transverse callosity. 

 The valve is short and very obtusely angu- 

 late. The last ventral segment is broadly 

 roundly extended backwards at middle. 



Described from one female and sev- 

 eral males in the National Museum, 

 collected at Los Angeles, Cal, by Mr. 

 Coquillett and at Dunsmuir, Cal., by 

 Mr. Wickham. These specimens bore 

 the Mss. name Lystridea avispetsa Uhl. 

 Ulheri seems to be entirely congeneric 

 with reuteri. 



Errhome»us lineatus n. .sp. Length of $ 

 7mm. Color pale yellowish brown. Head 

 slightly wider than pronotum. \'ertex 



bluntly angulate. nearly twice longer at 

 middle than at eyes, once and a half the 

 length of pronotum; numerous indistinct 

 brownish transverse arcs on front ; two black 

 dots near hind margin of disc of vertex. 

 Ocelli at about half length of vertex and 

 equidistant from median line and anterior 

 margin of vertex. Clypeus broad at base, 

 rapidly narrowing to the oval tip which pro- 

 jects beyond the genae. Pronotum short, 

 the width twice and three fourths the length, 

 fore and hind margin nearly parallel, the 

 latter broadly angularly emarginate ; laterally 

 distinctly carinate ; disc with a transverse 

 row of about six black dots ; anterior margin 

 with a conspicuous though not large black 

 spot behind each eye. Elytra obliciuely 

 truncate behind, not equalling second ab- 

 dominal segment, sordid vvhitish in color, 

 the discs of cells darker. Dorsum with a 

 double median longitudinal row of black 

 dots, each segment with about two trans- 

 verse rows of minute black points; the 

 spiracles in black dots. Sternum more or 

 less black laterally. 



Last ventral segment twice length of 

 preceding, the hind margin truncate, with 

 a very shallow median notch. Ovipositor 

 slightly exceeding pygofers. 



Length of $ S->~^' nim. Far darkei and 

 more heavily marked than the female. 

 Vertex shorter than pronotum and more 

 strongly irregularly concave. A more or 

 less well-defined dark median line extending 

 from point of vertex to scutel. All below 

 except legs largely black, sparingly irregu- 

 larly irrorate with yellowish ; a conspicuous 

 yellowish band extending from beneath 

 antennal pit back upon the proplurae. Fe- 

 mora lineate with dark. Dorsum black with 

 a few whitish points. Elytra exceeding 

 abdomen by about one mm., sordid white 

 with irregular dark cloudings in the cells. 

 Wings transparent, slightly smoky apically. 



Valve black, scarcely exserted, remainder 

 of genitals more or less sordid whitish.
