SO far consulted. In Biol. Cent. Am. Het. 2, 320, pi. 69, fig. 

 3 and 4, the male and female 7ie7imoegenn a^re figured. Whether 

 Jig. 4 is in reality the female netimoegenii may be considered 

 doubtful when it is known that a structural examination of my 

 series of over one hundred examples taken through three sea- 

 seasons fails to reveal a single female of this species. It is 

 therefore, my conviction that the female Megathymus neumoe- 

 gejiii remains unknown. The reference of ursus, an insect of 

 more than twice the average size of neumoegenii, with body 

 half an inch in thickness and more massive than any diurnal 

 known to our fauna as the female of the smallest species in the 

 genus to which it belongs is, however, too radical to be accepted 

 without positive proof, and it is for this reason that I bestow a 

 specific name on what I consider a described species. 



Lost Knowledge. 

 By C. F. Baker. 



The recent death of Dr. Lugger again calls attention to a 

 matter which has been discussed in various journals before. 

 Dr. Lugger was a special student of the Coleoptera and had a 

 very fine collection. He also studied Minnesota moths and had 

 started a valuable collection when I visited him years ago. It 

 was mo.st interesting to go over the beetles with him and listen 

 to his discussions of habits and obscure points in classification; 

 many facts concerning which, according to his orvn statement, 7vere 

 unpublished. He has departed to the "bourne from which no 

 traveller returns," and all that interesting array of knowledge 

 — the gatherings of many, many years of patient and scholarly 

 investigation — have gone with him ; for Dr. Lugger published 

 very little. 



Not long ago I reported on what I considered the solution 

 of a very vexing problem — one that had long puzzled me and 

 one that had consumed much time and thought. Soon after, I 

 received a letter from one of our old-time authorities, in which 

 he says : "What is all this fu.ssalx>ut? You are right, but i 

 have known all this for many, many years." He had known
