167. Orchisia costata Meig. 1826. 



Specimens of both sexes from Mount Maquiling, Laguna, and 

 from Baguio, Benguet. This species is rare in central Europe, 

 more common in southern Europe, and was described as Coenosia 

 marginata by Wiedemann from southern China. It was not 

 without emotion that I found in Professor Baker's collection 

 specimens of this pretty fly, identical with those which I find 

 here in the alpine valley of Susa, near Turin, on swampy places, 

 over Mentha and other aromatic herbage. 



It is interesting to note that at Baguio, Benguet, are to be 

 found three European flies: namely, Melanostoma mellinum 

 (orientale) , Mydsea duplicata, and Orchisia costata. 



168. Amphicyphus reticulatus Dol. 1856. 



Mount Maquiling. Identical with specimens from Calcutta, 

 India, in my collection; described from Borneo as an Ensima, 

 and subsequently recorded from Java. 



169. Campylocera thoracalis Hendel, 1913, var. rufina var. nov. 

 Female. — Similar to the type of the species from Maao, Negros 



(C. S. Banks), in the British Museum, but differing in the color- 

 ation of mesonotum. The four shining black longitudinal 

 stripes are in the present variety of a shining reddish color, 

 which sometimes is only very little darker than the surrounding 

 parts, and therefore the stripes are hardly visible. Chsetotaxy 

 of head (not distinct in Hendel's type) : Three ocellars, all bent 

 forward; one superior frontoorbital, bent forward; one post- 

 vertical, diverging outwardly; one inner vertical, directed in- 

 wardly ; one outer vertical, smaller and directed outwardly. 

 Luzon, Laguna, Mount Maquiling {Baker). 



Genus TYLOPTERNA novum 



This genus is erected for an aberrant ortalid, which shows a 

 very extraordinary appearance, having only a remote resem- 

 blance in the shape of head to the Ethiopian genus Pterageno- 

 myia Hendel, which is assigned by its author to the tribe 

 Trapherinse. 



Head broader than the thorax, truncate anteriorly, being in 

 profile view exceedingly narrow, while in front view it has the 

 aspect of the specimen figured by Hendel,^^ but it is less produced 

 upward. Head broader than high, having more the shape of a
