Typhlocyba pygm^a, Douglas. Plate LXXI., fig. 4. 



Male. Colour uniformly of a rich golden-yellow. 

 Vertex and pronotum unspotted, and of a pale brown 

 colour ; the lower half of the pronotum orange-yellow, 

 marked with two obscure brown dashes. Scutellum 

 crossed by one vertical and two diagonal brown lines. 

 Abdomen also marked by one vertical and seven or 

 eight horizontal bars. Apex ends with a singularly 

 formed sheath, which contains the genital organs. 

 Upper part of the frons orange-yellow ; lower part of a 

 greyish tint, and divided by a white line. Frons with 

 three minute punctures. Legs all bright orange. 

 Elytron orange-yellow, with faint brown streaks. 

 Wings hyaline, with a yellowish iridescent membrane. 



My figure of this unique insect is from a specimen, 

 kindly lent to me by Mr. Douglas. It has some 

 resemblance to the preceding species ; but its small 

 size and singular pygofer, amongst other variations, 

 appears to justify its claim to be a new species.
