202 THE entomologist's record. 



Thu^ tlie general appearance of the insect may tend to be male, with 

 the whole (or part) of tlie antenna;, -wing-rnarkings, colour, legs, &c., 

 showing characters normally associated with the female sex. In such 

 a case as this, how can the food-bond act ? It is difficult for me to ■ 

 see how it is possible for a portion, say of an antenna or wing to 

 absorb certain food-elements in the blood, even in the direction 

 indicated ]»y Dr. Wood, to the exclusion of the other parts of the same 

 structure, nor must it be overlooked that whereas the genital organs 

 undergo no histolysis, the fat-body from which the nutriment for the 

 building up of these structures is largely obtained, does undergo this 

 process before the histogenesis of many of the imaginal tissues at least 

 can take place. 



Perhaps Dr. Wood or some other biologist can help me, but at 

 present I am groping in the dark. I no more like the nerve-bond 

 than does Dr. Wood, as an explanation of the phenomena, yet it 

 seems to me that at present it is safer than the "food-bond," so far 

 as I understand it. I cannot conclude this short note without thank- 

 ing Dr. Wood for his very clever and interesting biological survey of 

 the subject, and I suspect that it is I who am at fault and that Dr. 

 Wood's theory is more sound than it appears to me to be. 



Further notes on the Fumeas.

Since writing my previous note on the Fumeas {autcu, pp. 59-62, 

 89-98, 121-125) I have had an opportunity of critically examining 

 the specimens of this group in the rich collection of M. Constant. It 

 contains several interesting forms, which illustrate very Avell the 

 great necessity there is for greater attention to these rather neglected 

 little moths. 



The series of six specimens representing Masonia sub/tavella is 

 calculated to throw grave doubt on the real distinctness of that species. 

 It consists of one specimen that may be 31. suhjiavella (or 21. craasio- 

 rella), one that is certainly a form of M. crassiorella with 22 antenna! 

 joints, whilst the four remaining specimens are the form I have 

 called Bruandia reticiilatdia var. ohscurella, and which may be the 

 French form to which Heylaerts has given the name norvctjica. These 

 specimens of M. Constant's have 22 antenna! joints and a spur lengtli 

 of -58. 



In the series oi M.crasfiioreUa is a remarkable specimen marked " D " 

 that did not strike me as being B. reticulatella var. ohscurella, yet had 

 some features of that form. I am not prepared to name it as a distinct 

 species till further specimens are forthcoming, but I think it is a neAV 

 species. Its expanse is 15mm., it is moi-e definitely reticulated than 

 B. var. obsciirclla is, it appeared to have a simple median vein, but this 

 is not perhaps certain, as I may have made my note to that effect 

 without making c^uite sure, fearing to damage the specimen. It has 

 22 antenna! joints and a very short tibial spine of length -53. This is 

 short for 77. reticulatella, but is probably within the extreme variation 

 possible for that species. 



Amongst the Fumea casta {intermediella) are two specimens taken 

 at Cannes, which may be a variety of M. subflarella, but are more 

 probably a distinct species. They expand 18mm., have 21 joints to
