1613] Melander — Some Acali/ptrate Muscilw 167 



given as a supplement to my paper. While in Philadelphia I 

 saw the proof sheets of Mr. Malloch's work, and while in Wash- 

 ington I examined his types. 



1. Sctdops Coquillett is not a Geomyzine. The post-vertical 

 bristles are strongly divergent; the costa is nowhere fractured; 

 the palpi are broadly spatulate; the first vein ends at the middle of 

 the wing and the auxiliary vein, although rudimentary, is sepa- 

 rated from the first vein, abruptly turning forward so as to termi- 

 nate near the middle of the costal cell. In addition, the lack of 

 oral vibrissse, the presence of the clypeus, the single pair of recli- 

 nate fronto-orbital bristles, the stiff bristles of the front femora, 

 the absence of preapical tibial bristles; and the shortened anal 

 vein, support its relationships with the Lonchreinse. The center 

 of the face is broad and flat, obliterating the facial orbits below 

 the antenna?. The face continues on the sides so as to line the 

 mouth-opening; the cheeks thus consisting of the face, gense 

 and buccse. 



2. Pseudiastata Coquillett belongs with the Drosophilinse. It 

 possesses the following characters which are at variance with 

 typical Geomyzinffi. The costa is fractured both at the humeral 

 crossvein and at the end of the auxiliary vein, where there is a 

 pronounced costal spine; the discal cell is confluent with the 

 second basal; the single frontal bristle is proclinate; there are 

 no mesopleural bristles; and the antennae are spaced apart. 



Mr. Coquillett was apt to over-stress some certain character, 

 such as the vestiture of the arista, and as he relied much on his 

 analytical keys, the microscopic pubescence of the arista of Pseu- 

 diastata led the genus to the Geomyzina?. A similar instance 

 occurred with Sinophthalmus, which presents more Drosophiline 

 characters than it does Geomyzine. Pseudiastata has the anal 

 cell present; the calyp teres ciliate; the post-vertical bristles 

 convergent; the oral vibrissse present; the clypeus visible and 

 moderately developed; the cheeks consisting of the gena-, buccse 

 and the sides of the face; the center of the face broad and flat; 

 the front pubescent; and the propleural bristle lacking. 



3. Spilochroa punctipennis, sp. nov. 



Male. Length 2.5 mm. Cinereous, black; body not spotted. Cheeks, face 

 and frontal orbits white-pollinose. Antennae brown, the third joint blackish,
