NEW AMERICAN BEES. 59 



margin of the pronotum is straight and very wide, the head 

 narrow (figs. 3-4). 



Elasmucha grisea ( = Acanthosoma inter stinctum, Saunders = 

 Cimex hetidce De Geer) is celebrated for its parental affection {cf. 

 'Entomologist,' 1903, p. 114). An early nymphal instar has a 

 remarkably produced head, the central lobe being twice as long 

 as the lateral ones. The species of Euri/dema (Stracliia) have 

 strongly coloured, cylindric eggs, with truncate ends. 



The nymphs of Tingidse are usually curiously spined, while 

 those of many Reduviids are sticky and so become covered with 

 dust, pollen, cast skins of their prey, &c. The eggs of Reduviids 

 are deposited, like those of Cimicids, on the surfaces of leaves, 

 and have ornamented caps of noteworthy form. The eggs of 

 Nabidae are inserted in plant-tissue, almost to their very end. 



Among specially interesting British Heteroptera, of which 

 the life-histories are only partially, or not at all, known, I would 

 suggest : Eysarcoris fabricii ( =: melanocephalus) on Stachys syl- 

 vatica ; Rhytidolomia ( = Pentatoma) junipei'ina on Juniperus 

 communis ; Eurydema oleracea on Cruciferae ; Elasmucha grisea 

 on Betula alba ; and MonantJiia cardiii on Carduus crispus. 

 These five are all common, at least locally, and should be easy 

 to observe and rear up. I may perhaps be allowed to refer to 

 two of my own papers which may be of interest in this connec- 

 tion, viz. : — " Upon Maternal Solicitude in Hemiptera, &c." 

 Entom. 1903, pp. 113-20. " Biological Notes on the Hemiptera 

 of the Hawaiian Isles. No. 1." P. Haw. E. S. i. 135-61 ; 

 4 text figs. 



My friend Mr. de la Torre Bueno has recently described the 

 stages of several waterbugs very fully in the ' Canadian Ento- 

 mologist.'

By T. D. a. Cockerell. 



Osniia copelandica, sp. nov. 

 2 . Length 7 mm. ; black, with a very faint Ijrassy tint on the 

 front, and the abdomen with an obscure purplish lustre, and the hind 

 margins of the segments very narrowly ferruginous ; ventral scopa 

 pure lohite ; conspicuous white hair at sides of face, sides of meta- 

 thorax, and to a less degree about tubercles ; first and second 

 abdominal segments with conspicuous white marginal hair-bands, on 

 the sides only ; hair on inner side of hind tarsi white tinged with 

 golden ; head and thorax densely punctured ; head large, cheeks 

 broad ; flagellum faintly reddish beneath ; mandibles tridentate ; 

 clypeus prominent, rather produced, the lower margin gently con- 

 cave ; tegulsB dark reddish ; wings a little infuscated ; abdomen 

 shining, finely punctured ; spurs yellowish-ferruginous, not dark ; 

 pulvillus large. A very distinct species, apparently related to the 

 European 0. adunca (Panzer), but much smaller.
