Sept., I9IS.] Felt: New Asian Gall Midges. 181 



June 8, 1914, and reported as having been reared from leaves of 

 Melia asedarach infested with Tctranychns species. 



Male. — Length .6 mm. Antennje a little longer than the body, thickly 

 haired, yellowish brown ; fourteen segments, the fifth having the stems with 

 a length one and one-half and two times their diameters, respectively ; 

 basal enlargement snbglobose, distal enlargement pyriform, with a length 

 equal to its diameter. Palpi : indistinct in the preparation. Mesonotum 

 dark reddish brown. Scutellum and postscutellum yellowish. Abdomen a 

 variable fuscous yellowish. Halteres pale yellowish. Legs a variable pale 

 straw. Claws slender, evenly cur\ed, the pulvilli nearly as long as the 

 claws. Genitalia: basal clasp segment rather stout; terminal clasp segment 

 long, slender ; dorsal plate deeply and triangularly emarginate, the ventral 

 plate short, broadly rounded apically. 



Type Cecid. a2579. 



Arthrocnodax walkeriana new species. 



The species characterized below was received from Prof. A. 

 Rutherford, Royal Botanic Gardens, Peradeniya, Ceylon, accompanied 

 by the statement that it was reared June 8, 1914, from a species of 

 Psciidococcus on coffee. There have been no species of this genus 

 described from that part of the world, and we therefore take pleasure 

 in characterizing this midge. Prof. Rutherford transmitted speci- 

 mens of apparently the same species reared at the same date from 

 Walkeriana species, probably kandycnsc. 



Male. — Length .i mm. Antennae as long as the body, thickly haired, 

 yellowish brown ; fourteen segments, the stems of the fifth antennal seg- 

 ment having a length one and one-fourth and one and one-half times their 

 diameter, respectively; basal enlargement with a length about half its 

 diameters, the distal enlargement globose, with a length three-fourths its 

 diameter, terminal segment slightly produced, the basal portion of the 

 stem with a length three times its diameter, the distal enlargement with a 

 length about twice its diameter and with an equally long, fingerlike process 

 apically. Palpi : first segment with a length twice its diameter, the second 

 quadrate, the third narrowly oval, the fourth one-half longer than the 

 third, more slender. Mesonotum reddish brown. Scutellum and postscutel- 

 lum yellowish. Abdomen a variable yellowish or yellowish orange. Hal- 

 teres and legs mostly pale straw, the distal tarsal segments darker. Claws 

 slender, evenly curved, the pulvilli nearly as long as the claws. Genitalia : 

 basal clasp segment rather long, slender ; terminal clasp segment swollen 

 basally ; dorsal plate short, deeply and broadly emarginate, the lobes diverg- 

 ing and narrowly rounded apically ; ventral plate long, rather broad, broadly 

 rounded apically.
