ihe fork; basai deflection of i?4 + 5 about two and one-half r-wi; ceil Mi lack- 

 ing; basai deflection of Cui far oui near the distal end of cell istM^, 

 tbe fusion of M3 and Cu\ about one-third m; C112 sborter than Ihe deflec- 

 tion of Cu\ . 



Abdomen velvety black; a çonspicuous ring on basai two-fifths of ter- 

 gite two and ât bases of tergites four and five glabrous, covered witli a 

 microscopic biuè-grey blooni, that of the second segment being more 

 nacreons. 



Habitat. — West G bina. 



Hoiotype, d*, Province of Se-tchouen (Sze-chuen), 1875 (Père 

 David). 



Type in tlie collection of tbe Paris National Muséum. 



Eriocera davidl is relaled to E. hilpa (Waik. ). In ibis latter species, 

 tergites two to six bave tbe basai balf or more subglabrous and sbiny. 

 In its abdominal jiattern, E. davidi agrées well wilb E. sinensis Edw., 

 likewise from Se-tcbouen, but ihis species bas tbe wing-base yellow as 

 in nepalensis Westw. Tbe Fly is named in bonor of tbe coUector, Père 

 David. 



Eriocera hilpoides nov. sp. 



Maïe. — Length, 10 mm.; wing, 10. 5 mm. 



Closely related to E. davidi, diflering as follows : 



Size smaller. Wiugs broader, dark brown, tbe anal cells faintly 

 darker; tbe wbile band before tbe cord completely crosses cell Cu into 

 tbe end of cell ist A; veins mucb paler brown, difficult to discern against 

 tbe membrane. Venation : Sci ending a sbort distance beyond r; Sc^ a 

 sbort dislance before tbe fork ofi?2+3, Sc\ sborter than tbe deflection of 

 Cîii ; Ii-2+i about twice tbe first section of 7?2; r on i?2 only about one 

 and one-balf its lengtb beyond tbe fork; basai deflection of /j/, + 5 more 

 tban ibree times r-m; cell ist M^ lacking; inuer end of cell ist M2 ar- 

 cuated, about as long as tbe second section of il/i + 2; fusion of M3 and 

 Cui about equal to ni.

Eriocera hilpoides is a member of tbe hilpa group, closely allied to 

 E. davidi as described above but distinct in tbe venation and pattern of 

 tbe wings.
