(bird segment. This is also rare. Mr. BigncU sent mc a pair some years ago bred 

 from Orgyia pudibunda, and Mr. Dale has one in bis collection reared from the 

 same insect. 



E. C1IEL0NIJ3, Rnd. 



This is also closely related to the two preceding species, but differs from them 

 both by having the middle abdominal segments armed with discal setae ; it resembles 

 E. lucorum by having the arista long and slender, and only slightly thickened at the 

 base, but has a rather narrow frontal stripe as in IS. gnava. Not uncommon. It is 

 in Miss Deeie's as well as Mr. Dale's collection, and Mr. Inchbald sent me several 

 specimens which he bred from Arctia caja and A. luhricipeda. 



ExoRiSTA LEUcopiT.EA, Mgn. nyi 



Colour grey, scutellum quite yellow, also palpi ; frontal stripe narrower than '^yjj j-'/"" 

 sides of the frontalia ; antennse with basal joints often partially red, third joint fully 

 four times as long as the second in the male, but not more tlian three times in the 

 female ; thorax with four stripes, the outer ones maculiform ; abdomen without red 

 marks on the sides, light grey with a few dark tessellations, discal setae very small 

 npon both middle segments, and often wanting altogether on the second one ; wings 

 yellowish ; legs with the tibise only partially yellow in the males, but sometimes 

 wholly so in the females. Eare. I have only seen one British specimen, which 

 was sent to me by the Rev. E. N. Bloomfield for identification. 



E. ALBICANS, Flu. 



This species somewhat resembles the former, but is only about half the size, 

 being not more than 4 — 5 mm. in length, and has only the tip of the scutellum 

 yellow ; the colour is whitish-grey, the antennae have the basal joints pale, and the 

 third about three times the length of the second ; the palpi are yellow ; the thorax 

 is striped in the middle with two very narrow lines, and has the sides almost im- 

 maculate ; the abdomen is tessellated with brown, has the front edges of the segments 

 pale, and the disc and edges armed with setae ; the wings are yellowish ; the hind 

 tibiae testaceous. Not common. I have found it near Lake Windermere, and it is 

 in Miss Deeie's collection. 



E. PERTURBANS, Ztt. 



This little species is very like E. albicans in general characters, but is much 

 darker in colour, and has the thorax more distinctly striped ; the antennas are quite 

 black, have the second joint very short (hardly longer than the first), and the third 

 five or six times as long, and also very thick, with the end pointed in front and 

 rounded behind ; the arista is thickened for half its length, and slightly pubescent ; 

 the palpi are testaceous, as well as the tibiae ; the wings are white or slightly ni- 

 grescent, without any yellow tinge. Rare. T have only seen one specimen, which 

 I captured near Bradford. 



E. FAUNA, Mgn. 



This species is characterized by having the legs quite black ; the palpi and 

 scutellum rufous ; and the middle abdominal segments without discal sette. The 

 forehead is prominent ; the thorax is greyish-black, shining and indistinctly striped ; 

 the abdomen is clear grey, marked with brown reflections, and has the dorsum 

 marked with a longitudinal black line, the hind edges of the second, third and fourth 

 segments are also black, and the first segment is quite black. Rare. IMr. Dale has 

 a specimen bred from C. ligniperda, and Mr. Bignell sent me one reared from the 

 same moth.
