STURMIA (BLEPHARIPODA) SEMITESTACEA, u. sp. 



This species is in size and general appearance like the European 

 S. sylvatica Fall. It belongs to a group of Sf a rut la in which the $ 

 has short fore claws, and the second abdominal segment is provided 

 with two marginal setae as much developed as in the 9 It is distin- 

 guished by : (1) the development of the ocellary setae which in length 

 and robustness approximate the inner vertical seta, and the same obtains 

 for the ascending frontal setae; (2) the colour of the abdomen; the 

 first segment is blackish above and under ; the second and third are 

 light testaceous red veiled by a greyish white down in the $ , denser 

 than usual in the $ , edged with black behind and crossed by an 

 obscure medio-dorsal baud ; fourth segment thickly ashy white. The 

 (J bears a large, black, ovate latero- ventral spot (resulting especially 

 from the compressed shape of the abdomen in the $ $ of this group ; 

 there are cases where this ovate spot is thrown out laterally) resting 

 on the hind border of segment 3, and covered with appressed and 

 closely set hairs ; another small and triangular patch is discernible on 

 the same level on segment 2. The scutellum rufous, with a dusting of 

 ashy grey thicker on the > and with two weak setae moderately long 

 and crossed at apex. Thorax ashy grey with the usual black lines : 

 dc. = 4 ; s_t. 2 + 1, sometimes 2 + 2. Head whitish ; orbits 

 slightly ashy, wider than the frontal band, which is black ; width of 

 vertex : = ~ of the eye ; $ = f of the eye. G-enae bare, as wide 

 as the orbits ; peristome as wide as the prominence of the frons in 

 front of the eye. On each side are two ascending setae, the others 

 reach the end of the second autennal joint, which is testaceous, and the 

 third is about four times as long and blackish. Above the larger 

 vibrissae are small reclining setae reaching beyond the lower third of the 

 epistome. Upper occiput without black setae behind the ciliae. Palps 

 cylindrical, yellow. Wings somewhat greyish, cubitus of the fourth 

 nervure almost straight, and with a short dark reflection in the form 

 of an appendage ; apical transverse weakly arched ; posterior trans- 

 verse little wavy, situated far from the cubitus ; costal spine absent ; 

 three ciliae at the base of the third nervure above and below. Squamae 

 whitish ; halteres testaceous. Legs black ; the tibiae sometimes 

 testaceous in the centre ; hind tibiae with long ciliae together
