 crested Regulus.) 



Plate VI. Fig. 4. 



Fulvous yellow ; head triangular ; abdomen with the 

 lateral fascia bright fulvous, terminating in pitchy chestnut. 



Head and thorax tawny yellow, the former triangular; 

 clypeus emarginate, with an oblong ovate depression, and 

 two diagonal lines from the antennae to the occiput, base 

 broad and truncate ; eyes black ; antennae yellow ; trabe- 

 culse small ; prothorax transverse, lateral and posterior mar- 

 gins rotundate ; metathorax not so wide as the head, sub- 

 triangular, posterior margin ciliated with stiff hairs ; abdo- 

 men ovate, dusky white, segments nearly equal, the lateral 

 fascia deep fulvous, shading into pitchy chestnut ; legs pale 

 fulvous ; femur thick and sub-angular. 



The first specimen of this species, which I had an oppor- 

 tunity of examining, was in the possession of the Rev. L. 

 Jenyns, since then I have obtained others, all of which were 

 from the Golden-crested Regulus (Regulus aurocapillus) . 

 The colour and extent of the abdominal fasciae is subject 

 to great variation.
