loo Dr. If. Scott's Note.'; un hioUtyij of some Inqu'dines and 



of the Cryptopliagid beetle Anlherophayus jxtllens, were 

 reared ; and lastly, (e) luimeious larvae of the Nitidulid 

 beetle Epiiniea depress^ (= aesiiva). 



Thus, the portion of the nest sent to nie contained a 

 good selection of the inmates enumerated by Mr. F. W. L. 

 Sladen in his book on " The Humble-Bee " (20, chap. iv). 

 The one which he mentions first was, however, absent ; 

 namely, the humble-bee wax-moth, Aplwmia sociella, to 

 the attacks of which he states that Bombus derhainellus 

 is specially liable. This insect may have been present 

 in the parts of the nest which I did not see. 



My thanks are due to Miss Cheesman, for giving me 

 the material, to Mr. A. W. Rymer Eoberts, for advice 

 on several points connected with the description of the 

 larva of Ejmraea depressa, and to Mr, K. G. Blair, who 

 took charge of the pupae of that insect for some time 

 during my absence. 



II. Brachycoma devia Fallen. 



This Tachinid fly is stated to devour the bees' brood 

 (20, p. 75). Four larvae were present in the nest, 

 one of which was killed and preserved, while fhe 

 other three pupated on or shortly before Jidy 30, 1918. 

 The puparia were kept through the winter in sand which 

 was moistened periodically, the contlitions being identical 

 with those described below under Antherophagus. One 

 adult emerged May 15-16, the other two May 18, 1919. 

 Sladen writes that the adult flies emerge in two or three 

 weeks. This probably refers to a summer generation ; 

 in ray material the pupal stage lasted nine months 

 and a half. Sladen also describes the puparia as 

 at first yellovvish-browji, afterwards dark red ; my three 

 examples are very dark. The determination of the fly 

 was confirmed by Mr. C. J. Wainwright. 



III. Aphiochaeta rata Wood and its parasite Orthostigma 

 pumilum Nees. 



I am indebted to Mr. J. E. Collin for determhiing this 

 Phorid fly. Two puparia found in the litter of the nest 

 were isolated, and adults emerged' from them respectively 

 Aug. 12, ($), and some time between Aug. 18 and Sept. 

 1, 1918 ($). A male of the fly was found ahve in the nest, 

 Aug. 16, 1918. 



Dr. Keilin has not studied this species in particular,
