Anoynala guttata. Plate XI., fig. 3 ; Plate XIII., figs. 16,- 

 17. 



Mycetophila gtUtata, Hutt. 



Length of antennae, 0-079; size of body, 0-174 x 044; 

 expanse of wing, 0-165 x 0-066. 



Antennae 2 + 14 jointed ; joints of seapus yellow, first 

 much longer than the second, which is cyathiform, surface 

 of both with a few stout short black hairs which are much 

 longer on the edge of the second joint ; first five or six joints 

 of flagellum yellow, terminal joints nearly black, length 

 usually about twice the breadth, all joints densely covered 

 with short hairs having bright silvery reflections. Palpi 

 prominent, rather large and thick, light-yellow, with a few 

 short hairs. A black shining patch round each ocellus, but 

 an orange area between them. Vertex dark-brown, with long 

 black hairs on the margin. Thorax dark-yellow, surface with 

 a few scattered hairs, which are long on the anterior and 

 lateral margins ; four longitudinal brown stripes, two short 

 ones extending from the collare to the insertion of the wings, 

 one on each side of the median line, but never confluent ; the 

 other two near the lateral margin, connnencing farther back, 

 and extending nearly to the scutellum, never confluent. 

 Scutelluni dark - brown anteriorly, light - yellow posteriorly, 

 fringed with long black hairs. Metathorax and pleurse dark- 

 brown. Halteres with light-coloured rather slender pedicels 

 bearing an oval club, light - yellow in colour. Abdomen 

 broadest in the middle, covered with hairs giving golden 

 reflection ; anterior portion of each segment yellow, posterior 

 and longer portions dark-brown. Legs rather short ; coxae 

 light-yellow, with black hairs on anterior surface ; femora 

 brown at both ends but yellow in the centre ; tibiae rather 

 stout, those of posterior and intermediate legs darkened at 

 both extremities and covered with short hairs and bearing 

 several spines of two sizes ; anterior tibiae only with shorter 

 spines ; tarsi light - yellow, but thickly clothed wdth dai'k 

 hairs ; spurs brown. Wings with brownish tinge, microscopi- 

 cally pubescent ; one brown patch between apex of first longi- 

 tudinal and costa ; another patch at fork of second and third 

 longitudinals, and a third on the inner side of posterior branch 

 of fourth longitudinal ; a more indistinct patch between ante- 

 rior branch of fourth longitudinal and posterior branch of 

 second longitudinal — i.e., near the margin of first posterior 

 cell. Second longitudinal joining costa not far before apex 

 of wing ; costa almost reaching the apex ; apex of fork of 

 third longitudinal much nearer the apex of wing than trans- 

 verse vein, the latter situated half-way along the M'ing ; fork 

 of fourth longitudinal nearer base of wing than junction
