26 INSECUTOR INSClTlyE M^NSTRUUS 



with golden brown scales. It has the size and the general 

 color of titillans. We found a male amongst the material. 



Genitalia : Side pieces about twice as long as wide, nar- 

 rowed a little at the middle. Apical lobe present with an inner 

 and an outer division, the inner division with moderately long 

 hairs, outer division with long hairs and filaments, one of the 

 filaments spatulate. Tip of basal lobe a stout rod, attenuated 

 at the middle, with rounded tip on which a short terminal 

 spine is inserted. A group of long hairs at the base of the 

 side piece. Clasp filament very stout, distorted, tapering to 

 tip, with a terminal spine and a long slender branch. Harpes 

 small, toothed at tip. Unci a stout basal cylinder. 



Mansonia arribalzagae Theobald. 



Mansonia coticida Dyar and Knab seems to be a synonym 

 of this species. 



COMMENT ON THE PRECEDING PAPER 



(Diptcra, CuHcidce) 

 By HARRISON G. DYAR 



Mrs. Bonne-Wepster and Doctor Bonne are to be congrat- 

 ulated on the valuable work, the results of which appear in 

 this paper. A few points of comment occur to me. 



Genus PHONIOMYIA Theobald 



This name is left in the air. The authors substitute Dyarina 

 for Phoniomyia Dyar (not Theobald), but are unable to cite a 

 male for Phoniomyia Theobald. One of Theobald's specimens 

 is shown to be a Dodecamyia, but not the type. Not im- 

 probably this rubbed female type will prove to be a Wyeomyia 

 or Dcndroniyia, and the name Phoniomyia can be dropped. 



Wyeomyia grayii Theobald. 



The authors state that the species has all the characters of 

 ahehcla D. & K. from southern Mexico. This presumably 

 refers to the characters of coloration, and not to the genitalia.
