EUPKOSOPIA LONGIFACIES Hendel 



Euprosopia longifacies Hendel, Genera Insectorum, Fam. Platystominae 

 (fig.) ; description, Abhand. k. k. Zool.-Bot. Gesellsch., Wien, vol. 8. heft 

 1, p. 350, 1914. 



This species was described from Formosa, and only the female is 

 known. Nothing is mentioned in the original description of a process 

 either on the tegiila or below it, but such a process or processes may 

 be present, as Hendel apparently paid no attention to the forward 

 production of the tegula in nigrojMnctata Hendel, though such a 

 process is present in two females identified by him which are now 

 before me. 



In addition to the characters listed in the key for the distinction 

 of longifacies from the next species I may mention the more dis- 

 tinctly vittate, and golden haired, mesonotum, and the less regular 

 and numerous dark spots on the wings.

 extremity of each antennal fovea and a streak of same color from

Figure 1. — Wing of Eupbosopia semiaemata 



occiput fuscous on each side of 



upper half and grey dusted, 



f rons brown on each side above 



and on ocellar region, and with 



grey dust on the orbital 



stripes on dark part ; antennae, 



palpi, and labrum testaceous 



yellow. Thorax fuscous, humeri not yellow, densely grey dusted, with 



three faint dark brown vittae; mesonotum with black decumbent 

 hairs; pleura concolorous with mesonotum, meso- 

 pleura not marked with dark spots; pteropleural 

 hairs dark in front, pale behind; scutellum pale 

 haired at apex. Abdomen colored as thorax, defec- 

 tive in type, but with traces of large dark brown 

 marks on the tergites, which are but poorly defined, 

 the short discal hairs black, the apical hairs pale. 

 Legs fuscous, tibiae largely yellow basally, basal 

 segment of each tarsus yellowish white on basal two- 

 thirds. Wing as Figure 1. Edges of calyptrae dark. 

 Head about 1.25 as high as wide in front (fig. 2) ; frons depressed 



in center, about 1.5 as long as its anterior width, outer verticals only 



present; arista haired on less than its basal fourth; facial carina 



microscopically transversely striate above, becoming granulose below. 



Humeral bristle present, posterior notopleural bristle on a slight
