stout process apically, the latter a component of the segment. Palpi : first 

 segment irregularly subquadrate, the second Yz longer, the third a little longer 

 than the second and the fourth Y2 longer than the third, slightly dilated. Meso- 

 notum, scutellum and postscutellum dark brown. Abdomen mostly deep red, 

 the dorsal sclerites somewhat fuscous, the short ovipositor pale yellowish. 

 Halteres and coxae pale yellowish ; femora, tibiae and tarsi mostly fuscous with 

 three distal tarsal segments of the posterior legs yellowish white. Ovipositor 

 about Yz the length of the abdomen, the terminal lobes with a length over thrice 

 the diameter and thickly setose. Type Cecid a.zjiZ'j. 



The midge described above was reared by O. A. Johannsen, 

 Orono, Maine, July 10, 1912, from reddish orange larvae preying upon 

 the false maple scale, PJiciiacoccus accricola King. The male is quite 

 different from any American representative of the genus, while the 

 female closely approaches that of D. gillettei, it being distinguished 

 therefrom by a difference in color and the longer, more slender ter- 

 minal antennal segment having a short, stout appendage with no 

 indication of partial segmentation, the latter condition existing in 

 D. gUlcttci. 



Dicrodiplosis californica, new species. 



Male. — Length 2 mm. Antennae probably as long as the body, sparsely 

 haired, yellowish brown; 14 segments, the sth with stems 34 and equal their 

 diameters ; the produced distal enlargement with a length about twice its diam- 

 eter and a distinct constriction near the basal third. Palpi : first segment ir- 

 regularly subquadrate, short, the second with a length only twice its diameter, 

 the third a little longer, more slender, the fourth ^4 longer than the third and 

 somewhat dilated. Mesonotum dark reddish brown, the submedian lines yel- 

 lowish. Scutellum and postscutellum yellowish. Abdomen reddish brown, the 

 basal segments yellowish ; genitalia reddish. Wings hyaline, costa light brown, 

 the third vein uniting with the margin just before the apex of the wing. Hal- 

 teres yellowish transparent, reddish apically. Legs a fuscous straw ; claws 

 long, slender, strongly curved, the pulvilli as long as the claws. Genitalia : 

 basal clasp segment long, stout ; terminal clasp segment long ; dorsal plate short, 

 triangularly emarginate, the lobes broadly rounded ; ventral plate moderately 

 long, tapering, narrowly rounded. 



Female. — Length 2 mm. Antennas about J4 the length of the body, sparsely 

 haired, reddish brown ; 14 segments, the fifth with a stem about Ya the cylindric 

 basal enlargement, which latter has a length nearly thrice its diameter ; terminal 

 segment only slightly produced, an obtusely rounded knob apically. Palpi : first 

 segment short, subquadrate, the second with a length twice its diameter, broadly 

 fusiform, the third about as long as the second, the fourth Y4 longer than the 

 third, somewhat expanded. Mesonotum dark reddish brown, the submedian 

 lines yellowish. Scutellum and postscutellum yellowish. Abdomen dark red,
