42 [July, 



Of the gonna OphthahnimiR three speeies are noted by Dr. J. Salilberg as having 

 been taken by him as far north as Karelia ; one of them (O. pi/gmeeus, F. Sahib.) 

 plentiful among lieather in August. The genus is hitherto unrepresented in Britain, 

 although many species inhabit the Continent, and some must be here. 



Tingispyri lives on the leaves of pear trees throughout Europe, often in such num- 

 bers as to occasion detriment to the trees, and hence known to French horticulturists 

 by the name of " le tigre." It is reputed to have been found in Britain, but I have 

 7iever seen a native example. 



Monanthia (PlatycliUa) pilosa, Fieb., is recorded as having been found in 

 France on the white horehound (Marnthium vuJgare) in July (E. Ferris, Ann. Soc. 

 Ent. France, iii, 76, 1873), and probably only wants to be looked for here in order to 

 be added to the British list. 



The above are a few of many species of Hemiptera that may reasonably be ex- 

 pected to occur in Britain ; the casual captures by the collectors of other orders in 

 fresh or out-of-the-way localities may soon, I hope, include at least some of them, or 

 perhaps others of the luimerous species that inhabit the Continent, and are not 

 debarred by any known cause from being resident here, but have not hilherto been 

 claimed as Britons. — J. W. Douglas, Lee : June, 1874. 



Additional notes on the egg-laying, S^'c, of Acanthosoma griseiim. — I have been 

 hoping for some time that I should see some notice of this species from the pen of 

 some one who had studied the Hemiptera, but failing this, I thought I would copy 

 out at full my notes made in 1871, of which I gave a very short abstract at page 13 

 of Yol. ix of this Magazine. 



On June 4th, 1S71, I noticed an Acanthosoma griseum on one of \hc lower 

 branches of my birch-tree, apparently engaged in extracting some nourishment from 

 the catkins ; she seemed quiet, and the under-side of her abdomen, near the tip, had 

 a greenish tint, suggestive of a batch of eggs soon to be laid; I saw her again on 

 the 5th, a little way off from her previous position, and again I found her on the 

 fith very near the same spot ; at 3 p.m. on that day I looked again, and found her 

 close to where she was on the 4th, and now engaged in laying eggs on the under-side 

 of a leaf. I did not sec an egg actually extruded, but I saw the whole batch gradually 

 placed in order. 



She began by depositing one egg, then a row of two or three, then about five, 

 till, at the widest row, there must have been seven or eight; then she diminished 

 the rows a^ain till she came to a point, the whole mass, in number between thirty 

 and forty, forming a rough diamond figure just about the size of her own body. 

 The outer eggs were laid on their sides, the inner ones stood up on end. I detached 

 one and examined it with the microscope, and found it long in shape, twice as long 

 as wide, plump, a little depressed on the sides, recticulated all over very faintly, 

 \ somewhat glossy, and in colour pale whitish-green. The mother now took her stand 

 \ over these eggs, but I do not think her body touched them ; towards the end of 

 June I noticed that the side of the eggs nearest the sun had become yellowish, and, 

 on the 29th, I found the young bugs all hatched, and clustered under their mother 

 amongst the empty egg-shells ; they were yellowish-green in colour, their thoraces 

 becoming darker than the abdomens, and I saw them moving their antenna.
