21. CucKJus dermestoides. On the 9th of April, in company with 

 two friends, I succeeded in capturing twenty-six specimens of this in- 

 sect under the bark of a tree that had been lately felled in Heinault 

 Forest, and was partially stripped of its bark. We observed that they 

 moved backwards with great facility ; the power of doing so must 

 be of great service to them, as from the very small space between the 

 bark and the wood it would, notwithstanding their flattened form, be 

 easier for them to go backwards than to turn. — Id. 



22. Sinodendron cylindricmn. On the 25th of April, being on my 

 way to West Wickham Wood, 1 dug this insect out of an old ash. — Id. 



23. Cerylon Hlsteroides, Rhyzophayiis crihratus and rirfus, Tomi- 

 ciis laricis and Aradus hetulce. On the 25th of April I found these 

 insects mider the bark of birch stumps in West Wickham Wood. — Id. 



24. PyrocJiroa coccinea. On the 1st of May under the bark of a 

 decayed oak : it had just assumed its perfect state, and the elytra were 

 of a pale cream colour : I put it into a pill-box, and on looking a few 

 hours afterwards the elytra had become of a faint reddish hue, and in 

 about twelve hours were of the usual bright red, although during the 

 whole time, except while I was looking at it, it had been secluded from 

 the light. — Id. 



25. Bitoma crenata. Under the bark of oak stumps in Heinault 

 Forest. — Id. 



26. Dioctria Meigenii. The following description of a new and 

 conspicuous dipterous insect, is a contribution to the British Fauna 

 for which I am indebted to J. Walton, Esq., who purchased it with 

 Millard's collection of insects, by whom it was captured in the vici- 

 nity of Bristol. Desc. Black, the moustache yellowish white. Tho- 

 rax with the usual white lines, and two humeral spots, and two just 

 behind the insertion of the wings close to the base of the scutellum, 

 reddish yellow. Legs testaceous. All the tarsi and the apex of the 

 tibia? brown. Wings hyaline, their base yellowish, and the apex of 

 the 3rd, 4th, and 5th segments of abdomen testaceous. Length 7^ lines. 

 Expans. of wings 13 lines. This conspicuous insect is a female, and 

 as large as the Dioc. (Elandica. It is dedicated with much pleasure 

 to the veteran Meigen,whose work on the order is a monument of skill, 

 patience and perseverance. — W. E. Shnckard ; Chelsea, May 6, 1841. 



27. Brepha Parthenias. I have captured and bred this moth from 

 the 26th of March to the middle of April. I believe its larva is very 

 imperfectly known, although Mr. Curtis, in his beautiful Avork entitled
