hairs. Posterior extremity of body witli a |)uir of long 

 caudal seta?, not si)ringing from the anal plates. 



Havitig only a single species with which to deal, it is 

 dirticult and inadvisable to define the generic characters very 

 minutely. 



I have still further difficulty in dotermining the proper 

 systematic jiosition of the new genus. It has somo characters 

 (stigmatic spines, anal cleft, &c.) which associate it with the 

 Lecaniina?, others which suggest Dactylopiinaj, but not such 

 as would warrant its inclusion in the intermediate family 

 Hemicoecina', where the larvte arc Dactylopiinid and the 

 adults Lecaniinid. 1 think that the Lecanoid characters 

 have here the predominance, the principal differences being 

 the non-valvular anal j)Iates and the marginal position of the 

 caudal seta?. 



The name of the genus is taken from that of the locality 

 in which the specimens were collected. 



Birchippia anomala, sp. n. (PI. XI. figs. 3-3 d.) 



Test of adult female corneous, semitransparent, fulvous, 

 more or less obscured by a fragmentary coating of brownish 

 waxy matter. The dark body of the dead insect can be 

 distinguished through the test at the anterior extremity. 

 Broadly oval to oblong-oval according to position. Strongly 

 convex above, smooth. A small circular opening at the 

 ])Osterior extremity. 



Length 3-4 niillim. ; breadth 2 millim. 



Male puparium whitish, opaque. Kather broadly oval, 

 with a circular valve-like opening at posterior extremity. 

 ]\]oderately convex above, more so above the abdominal area. 

 Surface marked by numerous transverse depressed lines and 

 usually four longitudinal furrows ; the area between the two 

 median furrows standing up as a rounded ridge. Tlie general 

 character of the puparium is strongly suggestive of that of a 

 male Lecaniodiaspid. 



Length \2o millim. ; breadth 0"75 millim. 



Adult female (fig. 3) shrivelling to anterior part of test, 

 subcircular (after maceration). Posterior extremity cleft. 

 ]\Ientum nionomerous. Antenna (fig. 3rt) atrophied, varying 

 in development in different individuals. In some examples a 

 distinct basal and a compound terminal joint only can be 

 distinguished. In others at least three distinct joints are 

 present, the median as long as the other two combined. The 

 terminal joint has two or more imperfect divisions and bears 

 six or seven stout bristles at its extremity. On the margin,
