 Thrush.) 



Plate IV. Fig. 5. 



Head and thorax chestnut-yellow, the former oblong, 

 much produced in front, with two broad bands ; abdomen 

 nearly orbicular, with deep chestnut fasciae. 



Head elongate, anterior portion produced ; clypeus broad 

 and emarginate, with a deep acuminate depression ending 

 in a fuscous spot at the vertex, lateral margin sinuated 

 before the eyes, two broad deep chestnut bands extending 

 from the trabeculae to the occiput ; eyes black ; antennae 

 pale, fulvous yellow, the sides of the joints with a dark 

 spot, the second joint the largest; trabeculae large and 

 strong, rather blunt ; prothorax transverse ; metathorax 

 the width of the head, triangular ; abdomen short, nearly 

 orbicular, yellow white, the first and last segment but one, 

 with the lateral fasciae of the remainder deep chestnut 

 brown, sutures deeply sinuated posteriorly, and ciliated 

 with yellow hairs ; legs fulvous, yellow ; anterior femora 

 securiform. Length \. 



In some species the abdominal fasciae nearly unite in the 

 centre. This species is readily distinguished from D. 

 Merulae by the greater length of the head, angular meta- 

 thorax, more slender legs, and generally smaller size. I 

 obtained my specimens from the Song Thrush (Turd us 

 musicus) .
