clasp-shaped organs are dark brown, the projecting finger-like organ 

 (which in dried examples may be the only portion visible) yellow or 

 pale amber, with fine black hairs : this organ often bears a solidified 

 globule (indicated by dotted line in figure) of about the same color 

 and texture, which might easily be mistaken for a portion of the 

 insect. 



9. — The larger examples (dried) slightly exceed 3 mm. in length; 

 colors of head and thorax, and chaetotaxy, practically identical with 

 those of the $ ; the proboscis, in living or freshly killed material, is 

 almost twice as long as that of the $ , is horny, and is usually held 

 vertically as shown in the figure ; in dry examples it is drawn up 

 obliquely or horizontally between the palpi, but exceeds them in length 

 by fully its own width ; in this sex the second joint of the antenna 

 is usually visible and is yellowish-brown; the abdomen of the $ is 

 more dilated and less strongly chitinized than that of the 5, the 

 longitudinal striations (indicated in the figure) are more marked, and 

 the velvety black and yellow of the male are replaced by dull smoky 

 brown; terminal joint of the hypopygium pale amber, usually drying to 

 dark brown. 



Described and illustrated from numerous eggs, larvae, and 

 puparia, and from nine male and six female flies, bred from 

 dead insects contained in the pitchers of Sarracenia ftava, Sum- 

 merville, South Carolina.

The Rev. O. Pickard-Cambridge and His Collection of Arachnida. 



According to the Entomologist's Monthly Magazine for August, 1918, 

 a "Memoir of the Rev. Octavius Pickard-Cambridge" by his son, A. 

 W. Pickard-Cambridge (Oxford printed for private circulation, 1918) 

 has appeared, giving a biographical sketch and a "very complete 

 bibliography of the scientific papers" of its subject. The "great 

 series of Arachnida, with its numberless 'types' brought together 

 during his long life and the extensive library of works relating to 

 the class have found a final resting place in the Oxford University 

 Museum and are now available to all students of the subject."
