ON SOME RACES OF LASIOCAMPA QUERCtlS. 339 



are two <? s, which emerged July 11th, 1900, and August 7th, 1900, 

 after an extra year of pupal life. They are odd enough in their looks. 

 They are of a dark mahogany-hrown tint, different from any of the others, 

 thinly scaled and partly decolorised, with small dots, a narrow sharply- 

 defined band on the forewings, and a quite thin not very marked line 

 on the hindwings. Their markings do not suggest their parentage, 

 and they would hardly be taken for qnereiis forms at all. The only 

 other specimen they at all resemble is one of the second year [(9 X 2) x 9] 

 batch. I still have many pup^e remaining over, possibly alive.

 — About July 1897 I had an unfortunate accident with my pupa cage. 

 It was knocked over by a curtain, blown by a draught in the room, and 

 several of the pups were spilt out of their boxes. I sorted them out 

 as well as I could, but there is a slight degree of doubt in some which 

 I have marked with a ?. The female parent in this case was, however, 

 almost certainly a sieida. The ova, lot 3660, obtained from the above 

 parents on August 12th, 1898, were large, mottled with red-brown. 

 They all hatched on September 3rd, 1898, and after. Before their 

 first moult the larvfe were very similar to lots 3640 [= <? (9 x 2) x ? 

 (6 X 6)] and 3616 [ = <? (9 x 7) "x ? 10] , except that there seemed to be a 

 more conspicuous black segmental division between segments 2-3 and 

 3-4. There were also scattered long black hairs. I have no further 

 notes about them after the first moult (September 14th, 1898). The 

 emergences extended over two years and were very erratic. So are the 

 results. All specimens were small. The 3^ parent as before stated 

 had large dots, the four 3" descendants minute ones. The two males 

 emerged in the first year (April 1899) are good intermediates both in 

 colour (which is duller in these than in any of the others) and in 

 markings. The whole border of the hindwing is a brown just about 

 midway between the chestnut of var. H(('?7f//o»«^/.s-and the dark brown of 

 var. aicula, just lightened up with a thin orange-yellow line inside, which 

 is even smaller than the band in var. meridinnalis. The ? of the first 

 year is lighter than the ? parent, and shows the influence of both 

 races. The two <? s of the second year did not appear in April, but 

 in August 1900 and in the winter following." The first of these 

 was a decolorised thinly-scaled specimen, similar to the first year's, 

 the second a washed out var. sictda in appearance with nothing to dis- 

 tinguish it from the pure race. The two second year 5 s were darker 

 and slightly crippled. I ought to note, as it has been shown to 

 influence var. sicida, that the winter of 1898 Avas the last that I spent 

 in Cannes, so that crosses obtained after that were reared entirely in 

 England. 



(4) L.hybr.<3^ sicida x ? {meridionalis x vihurni){= J 9 X ? 7). — The 

 (? parent was the same as in the 9 J x 2 ? brood described, the ? a 

 fairly dark nicely marked specimen. This pairing was obtained by 

 Mr. Bacot (V, August 24th, 1897), who reared 400. My larva, 

 described when l^in. long, closely resembled those of (7<? x2?). 

 They had the dorsal area very red-brown-haired, but more long white 

 hairs were sprinkled over both back and sides. Face rusty-red. I 

 obtained 17 pupte. I am not able to say how many imagines emerged 

 (July-September, 1898), as this box full suffered very severely in the 



* No record was kept of moths, which, coming out unexpectedly, damaged 

 themselves irreparably.
