92 THK ENTOMOLOGISTS RECORD. 



The larvffi always left the seedheads for pupation. I dare say the 

 species occurs now on the wnste areas there wherever burdock grows. 

 Any way, though for the purpose of Practical HinU I should have 

 been glad to have used Machin's note, I knew all about the larval 

 habits of A. badiana in those days, and remember them still. I believe 

 most of the authorities say it feeds in the stem which is, I believe, 

 quite erroneous. — J. W. Tutt. 



Notes on British records of Sirex juvencus, F. — On looking 

 over the Kntonwlotiist's Record, and carefully reading the note of Mr. 

 Joseph W. Anderson, I think it well to record the particulars con- 

 cerning three specimens of Sirex that I have in my collection. One 

 taken on the London Fields, Hackney, on July 20th, 1891, and 

 brought to me damaged after being smoked to death, and kept in a 

 match-box for some days. The second taken at Eltham by my late 

 brother Joseph Clark, Heptember 27tb, 1896, and the third taken in 

 Abbotts Wood, July 7th, 1903. All these specimens have metallic 

 blue-black bodies. Two have blue-black antenna, but the one taken 

 on the London Fields, seems to have black antennae. Many ento- 

 mologists have seen them, and have always called them Sirej- jnvcncits. 

 It seems strange that the date of occurrence and the districts are so 

 widely separated. Compare Mr. Joseph W. Anderson's note. Ento- 

 mologist's Record, vol. xix., p. 265, and mine as above. — J. A. Clark, 

 F.E.'S., 57, Weston Park, Crouch End, N.

Ovum of Ochsenheimeria vacculella, F.-R.— In August, 1906, I 

 enclosed two or three females of this species from Richmond, Surrey, 

 in a box with some Poa annua. Many eggs Avere laid, some along the 

 inner face of a dried leaf near the base, others in the sheaths of the 

 lower leaves close to the root of the grass. They were more or less in 

 pairs, and touching each other. Colour very pale ochreous, and some- 

 what shining. Fusiform in shape, more than twice as long as broad, 

 with the micropylar pole truncated, usually obliquely, and the opposite 

 pole rounded or bluntly pointed. Sometimes the eggs appear to be 

 slightly flattened. Length 0'55mm. Width, in widest part, 0-23mm. 

 Irregular coarse furrows or wrinkles run from end to end of the ovum. 

 Sometimes these rather deep furrows coalesce, or they form a sickle- 

 shaped bend in their course, and then continue. At the micropylar 

 pole are some large, more or less kite-shaped, cells, but weakly-marked, 

 and in the centre of these are about eight small and strongly marked 

 cells, which enclose the micropyle. — Alfred Sich. 



Ovum of Borkhausenia pseudospretella, Stt. — Colour very pale, 

 ovoid in shape, the long axis about 0-55mm., the two others nearly 

 equal, about 0-87mm. The micropylar pole, which is flattened, is 

 larger than the opposite rounded pole. The sculpture consit-ts of about 

 twenty longitudinal grooves which run from pole to pole. Towards the 

 micropylar area the ridges between the grooves become rather sharp, 

 and they are crossed by slight secondary ridges. The result is thatslight 

 irregular elevations are formed which give the egg a rough appearance 

 at the top. The rosette is composed of seven or eight elongated cells 

 of much the same size and shape, and having their outer extremities
