Chelicerse not quite twice as long as ihe face is high. Anterior row of 

 eyes a little longer than the second, nearly straight; anterior median eyes 

 much larger than the lateral, at most one-fifth their diameter apart, still 

 closer to the lateral eyes, not fully one-third their diameter from eyes of 

 second row ; anterior lateral eyes not fully their diameter from front margin 

 of clypeup, some closer to eyes of second row ; anterior median eyes three- 

 fourths as large as those of second row ; eyes of second row about their 

 radius apart ; quadrangle of posterior eyes as wide in front as long, only 

 one-sixth as long as cephalothorax. Spines of anterior tibiie greatly 

 reduced, minute ; none at all on either anterior or posterior side of joint. 

 Epigynum nearly the same as that oi funerea. 



Total length, 6.6 mm. Length of cephalothorax, 3.2 mm.; width, 

 2.25 mm. Length of leg iv., g.4 mm. 



Locality : Louisiana. 



The other species of Allocosa so far described are fiinerea^ Hentz ; 

 rugflSiii Keys {nigra, Stone, v.qc funerea) ; and si/b/ata, Montg. I have a 

 fifth species not yet described. 



STRANGE ATTEMPTED HYBRIDIZATION IN NATURE. 

 It will doubtless be of interest for me to record what seems to me the 

 strangest cross-copulation between different species of lepidoptera that I 

 have ever heard of. ISIr. Arthur Hudson informs me that one night 

 recently he found on a treacled post a ■$ Ort/iosia Coriradi in coitu with 

 a 9 Noctua Sinithii, and on the same night on another treacled post, a 

 ^ Xylophasia lateritia in coitu also with a 9 -^ Sfnithii. Both pairs 

 remained in cop. for some little time after boxing; but the 9 9 died, 

 probably from dry heat, within about twenty-four hours, without laying. 

 Mr. Hudson's dictum on matters concerning the habit.<^, etc., of our local 

 lepidoptera is unimpeachable, and he says there cannot be any doubt as 

 to the species in each case. Of course it is unlikely that, had eggs been 

 obtained, they would have proved fertile. During my 17 years' experience 

 as a collector I never yet saw even supposed different species in cop., and 

 never heard of copulation between species so widely distinct. The 

 occurrence of the two cases on the same night would seem to suggest that 

 something about the atmospheric conditions had turned the moths a bit 

 "crazy."— F. H. Wolley Dod, Millarville, Alta.
