THE CANADIAN ENTOMOLOGIST. 53 



very close punctuation, clypeus with lateral projecting angles ; tongue 

 apparently rather short, nearly as in Heviilialictiis ; mesothorax dull and 

 granular from the excessively close punctures ; base of metathorax semi- 

 lunar, with fine longitudinal plications or striae ; tegulae piceous. Wings 

 smoky, iridescent, nervures and stigma black or piceous ; stigma rather 

 small, basal nervure noticeably but not abruptly bent ; second submar- 

 ginal cell about as long as the first, receiving the first recurrent nervure at 

 less than one fourth from its base, and the second (at a right angle) about 

 one-sixth from its tip. Legs black, with whitish hairs ; hind legs with a 

 rather abundant scopa, carrying considerable yellow pollen. Abdomen 

 hardly punctured, except that the first segment near its base exhibits large 

 scattered punctures ; hind margins of segments pallid ; apical half of 

 abdomen pruinose with pale hairs. 



Hab. — Five taken by Prof. J. D. Tinsley at flowers of Gymnolomia 

 multiflora., in Soledad Canon, Organ Mts., New Mexico, 7,000 feet alt., 

 Sept. 25, 1897. I am not quite sure about the generic position of this 

 little bee. The tongue suggests Hemihalictiis, but the wings are entirely 

 those oi Halictoides, and differ from Hemihalictus. I sent an example of 

 H. Tiiisleyi to Mr. W. J. Fox, who kindly compared it with Cresson's 

 types of " PajinrguSs' and writes that it "is apparently different from any 

 here. It is not fimbriatus, which has the abdomen much more hairy. 

 It may be the 9 o( nigrifrons, hut I am inclined to think not." (L/tf., 

 Nov. 5, 1897.) ^^__ 



ON THE DIPTEROUS GENUS EUSIPHONA. 



BY D. W. COQUILLETT, WASHINGTON, D. C. 



At the time of establishing this genus, in my recent revision of the 

 Tachinidie, I had only two specimens before me ; in both of these the 

 wings are bent backward in such a manner as to prevent a critical 

 examination of the lower calypteres, but as the specimens otherwise agree 

 quite closely with the Tachinid genus Gymnophania, I concluded to place 

 the present genus next to it. The recent examination, however, of a 

 perfect specimen from Mr. Charles Robertson, of Carlinville, Illinois, 

 reveals the fact that the lower calypteres are extremely small, being, in 

 fact, rudimentary, and this genus must therefore be transferred I'rom 

 the Tachinidae to the superfamily Acalyptrata. In all the essential 

 characters it agrees with the family Agromyzidae, and its proper place is 

 evidently in the vicinity of the genus Desmometopa, from which it will be 

 readily recognized by the strongly convex front and the excessively 

 long, bristle-like proboscis.
