hirticollis, repanda and its varieties, and less conspicuously in 

 Ihnbata, the emargination lies not upon the median line of the 

 body, but noticeably to the left. A somewhat similar sexual 

 asymmetrical modification of the last ventral has been recorded 

 in the Pselaphide genus Sonoma (Faronus), and in the Staphy- 

 linide genus Palaminus, but so far as I know the peculiarity is 

 common to all species of these genera. It therefore seems very 

 remarkable that so aberrant a structure should affect this small 

 number of species in the very midst as it were of a homo- 

 geneous genus. 



The last of three above named sexual characters males with 

 the intermediate tibiae externally pubescent females glabrous, 

 I can not all appreciate. The difference seems to me to be 

 merely comparative, at least I have not yet found a specimen 

 which does not show this pubescence, and while it is usually 

 more conspicuous in the males, in not a few cases the difference 

 is so slight as to be barely perceptible. 



A character which in very many species possesses a positive 

 value, and to which I do not remember to have seen any allusion, 

 exists in the extent of the pubescence which clothes the sides of 

 the abdominal segments. In the males of most species the pubes- 

 cence is always of nearly equal density on all the segments, 

 while in the females the last segment is either entirely glabrous, 

 or with at most a few hairs at the base. Dorsalis, puritana, 

 lepida, gabbii, togata, scutellaris, tenuisignata and sigmoidea 

 among others well illustrate this point. In some species (recti- 

 latera, circumpida) the pubescence ends' abruptly with the fourth 

 segment, and occasionally (yu/garis, abdominalis) the last three 

 segments are unclothed. It is worthy of mention that the females 

 of the western varieties of repanda (pregona an&guttifera) entirely 

 lack the pubescence at the sides of the abdominal segments ; at 

 least this is true in the fairly good series which I possess, and 

 will, I suspect, prove characteristic. 



IN the. Deutsche Ent. Zeits. 1895, p. 58, Mr. J. Weise suggests the new 

 generic name Fabricianus for our Cryptocephalus auratus. I n 1 880 (Trans. 

 Am. Ent. Soc. viii, p. 196), Dr LeConte suggests the name Diac/iits for 

 the same species and six others. In the Biologia i, p.' 149, Mr. Bates 

 describes a Bembidium lucidum as a new species. The same was de- 

 scribed by Dr. LeConte under the same name in 1848, Ann. Lye. iv, p. 

 466. G. H. HORN.
