arcs of circles, the curve in front; below these stripes and in same line, from third 

 to last segment, is a spot on each, which on third and fourth is lunate, but from 

 fifth to twelfth is a right-angled triangle, one of the short sides being in line with 

 the posterior edge of the stripe, the other parallel with the line of the stigmata ; 

 there is also an infra-stignuital row of spots, one on each segment after the first, 

 and there is a single spot on each leg and pro-leg ; the last segment has three spots 

 on dorsal line, the central round, the others abbreviated sti'ipes ; one such stripe 

 also on either side ; at the intersection of the segments from second to last, a 

 black stripe crosses the dorsum and ends midway down the side ; color bright pea- 

 green, changing to yellow-green on sides and beneath ; tlie legs tipped with black ; 

 head ob-ovate, yellow-green, striped vertically with Ijlack ; retractile horns bright

Brevicuuda was first made known by Professor Packard, who prefaced Mr. 

 Saunders' description by these words : " Mr. Saunders has received from St. Johns, 

 Newfoundland, several specimens of a butterfly, one of which I have before me, 

 and which seems to be a very remarkable variety oi Aster las." The next notice 

 on record is from Mr. Couper, in Can. Ent.,Vol. IV., p. 202, Nov. 1872, who, in 

 a paper on the insects taken by him that year on the Island of Anticosti, mentions 

 having four specimens of this butterfly. In 1873, Mr. Couper again visited this 

 island, and succeeding in taking many more, as well as in discovering the larva 

 and egg. In Can. Ent., Vol. V' I., p. 3.3, for February, 1874, he says that he had 

 formerly taken a single specimen of Brevicauda on the coast of Labrador, and that 

 he had made inquiries as to its existence in Newfoundland, and is satisfied that it 

 is a rare species on that island ; quoting from a correspondent, who states that he 

 had seen but one specimen in three seasons, and further, that he had heard of this 

 butterfly at Cod Roy, on the western coast, and at Notre Dame Bay, on the north 

 of the island. Mr. Couper continues: '-I am confident that it becomes rare a.s 

 we proceed down the south coast of Labrador towards the Straits of Belle Isle. 

 Its true habitat is the island of Anticosti, where it occurs more abundantly than 

 in Labrador or Newfoundland. It is met with occasionally at Mingan, but more 

 especially at the mouths of rivers east of Seven Islands." Mr. Couper has kindly 

 furnished me extracts from his note-book as follows : " Brevicauda was noticed 

 and a specimen taken at Ellis Bay, 14th June. Fi-om the latter date, as the 

 weather became warm, forty specimens were taken up to 26th June. The female 

 deposited eggs, 25th June, on Archangelica purpurea (see Plate), and I have 

 also found eggs on Heracleum lanatum, but the former plant is its principal food, 

 and occurs abundantly throughout the island. The egg is laid singly on the
