tudinal fork somewhat divergent ; second posterior cell short, 

 its base situated much beyond the base of the second sub- 

 marginal cell ; the branches of the fourth longitudinal fork 

 divergent ; fiftli longitudinal vein long, incomplete ; sixth 

 longitudinal vein long. 



This genus was established by Skuse for some Australian 

 species. None have hitherto been described from any other 

 country. 



Bracliydicrania hiemalis. Plate XI., fig. 2; Plate XIII., figs. 



18, 19. 



Length of antennae, 0-055; size of body, 0-154 x 0-022; 

 expanse of wing, 0143 x 0-049. 



Antennte about as long as head and thoi'ax ; joints of 

 scapus dark-yellow, setiferous ; joints of flagellum rather 

 longer than broad, difficult to distinguish near the base, but 

 separated near the apex, dark-brown, but covered with a 

 short dense pubescence giving a silvery reflection. Palpi 

 long and slender; first, second, and third joints light-yellow; 

 basal half of fourth joint light-yellow, apical half dark-brown. 

 Front dark-brown, covered with rather short hairs. Thorax 

 dark-brown, humeri and lateral margins dark-yellow, short 

 yellow hairs and longer black ones covering its surface. Scu- 

 tellum dark-brown, bordered with a few very long black hairs. 

 Metathorax and pleurae brown, smooth. Halteres with white 

 pedicel ; club smoky. Abdomen rather slender, covered 

 sparmgly with black hairs ; first and second segments brown 

 with yellow sides, and sometimes yellow on posterior margin ; 

 third segment dark-yellow, brown on centre of dorsal surface; 

 remaining segments black. Legs long and slender ; coxae 

 almost white, smoky towards the tip ; femora very light 

 yellow ; tibiae pale straw-colour, but covered with black hairs 

 arranged in longitudinal lines, and two rows of long slender 

 spines on intermediate and posterior tibiae ; tarsi nearly black 

 from dense clothing of black hairs ; those of anterior legs 

 very long, shorter in intermediate, and about as long as tibiae 

 in posterior legs; spurs very long and slender, pale-brown. 

 Wings microscopically pubescent, the pubescence being 

 arranged in longitudinal lines ; pellucid, with a very pale tint. 

 Auxiliary very short ; first longitudinal nearly parallel with 

 costa ; second longitudinal and anterior branch of third 

 longitudinal slightly sinuate; marginal cross - vein situated 

 beyond apex of second submarginal cell, about lialf-way along 

 first longitudinal vein ; neither branch of fourth longitudinal 

 reaching the margin. 



This insect was extremely common on window-panes and 

 in low-lying bush in Wanganui in June and July. Closely 

 allied to B. jmllicanda, of Australia, but, I think, distinct.
