their cocoons on the 7th, and emerged on the 23rd of March 

 in that year. 



Mr. Lamborn's note, dated 24th March, 1912, is as 

 follows : — " The larvae were pale green in colour, with a 

 median longitudinal black band on the dorsal aspect, and 

 they were covered with short hairs. The thoracic legs were 

 brilliant scarlet. When one touched a larva it suddenly 

 threw back the anterior portion of its body, bringing the 

 ventral surface uppermost, so that the legs were prominently 

 displayed. They were then quivered violently." 



Three larvae, all of the same age, were found on one small 

 plant, growing at the side of a forest-path. 



Zygaenidae. 

 Salianca egeria, sp. n. 



<$ . Head, antennas, thorax, and abdomen black ; patagia 

 chestnut-brown. Primaries chestnut-brown, rather darker on 

 the fold and towards the termen ; a long, dusky, wedge-shaped 

 mark between veins 5 and 8, rapidly tapering through the 

 cell. Secondaries uniform sooty brown. 



Expanse 30 mm. 



Hab. Bugalla, Sesse Islands, in the N.W. of the Victoria 

 Nyanza. 



Type in the Oxford Museum. 



This specimen, the only one seen by Dr. Carpenter, was 

 captured at rest on a grass-stem, Jan. 21, 1912, in an open 

 grassy area on the island. Dr. Carpenter notes that at rest 

 the wings are disposed flat over the back, with costal margins 

 [? inner margins] loosely apposed. In this attitude the moth 

 closely resembles some of theLycid beetles which are common 

 on the island.
