or markings; but is constantly smaller, the autumn brood of adults now held by Mr. 
Blackwall to be the true Epeira inclinata being invariably larger. 
Young spiders hatched from this autumnal adult brood hybernate during the winter, 
and become adult in the following May and June, having had no advantage of an abun- 
dance of insect food, such as falls to the share of their progeny. These, hatching in the 
height of summer, are abundantly, and without interruption, supplied with food up to 
the time of their maturity, whence we can easily understand their attaining a larger size 
than their more scantily fed progenitors. The individuals of the autumnal brood, how- 
ever, though in general considerably larger than those of the spring brood, are by no 
means of uniform size, as I have occasionally found ee of the former very little, 
if at all, larger than the latter. 
Since writing the above, I perceive that Dr. Thorell’s opinion on the distinctness of Mr. 
Blackwall’s species, Epeira Mengii, coincides with my own. (See Thorell, loc. cit.)

The dissections of the palpi of this species are from an example of the adult male found 
at Bloxworth ; the serrated edge of a portion of the palpal organs and the series of minute 
spines on the front of the falces are distinctive specific characters. 
I have recently received adult males of this species from Berwickshire, where they 
were found by Mr. James Hardy. :

This spider was met with in abundance among moss and weeds in a swamp near Blox- 
worth in May 1863.

An adult male was received recently from Mr. James Hardy, by whom it was found in 
Berwickshire. Neither this nor the foregoing species has ever been figured before.
