THE ENTOMOLOGIST. 



(1851 (v.), 7, p. 250), "fovea frontali . . . oculos vix superante," 

 and Europ. Hemipt. (1861, p. 99), " Stirngrube . . . die Augen 

 fast uberragend," would apply well enough to intricate, were it 

 not that in the latter the frontal fovea distinctly, though by very 

 little, extends backwards beyond the apical margin of the eyes. 

 Fieber's figures in the ' Abhandlung ' (tab. ii., fig. 26) do not 

 give at all a good idea of the palse. The same author's descrip- 

 tion of cognate (Eur. Hem., p. 99) applies well enough to sharpi, 

 " Stirngrube ... an das obere Augenende reichend." Puton 

 (1880, Syn. Hem. Prance, p. 234) considers germari(=:vtoriegata= 

 intricate) as only a colour-variety of carinata (= cog nata= sharpi). 

 Wallengren, however, in 1894, in his revision, in Swedish, of the 

 Scandinavian Corixae (Ent. Tidskr. xv., pp. 129-164) separates 

 his variegate (1854) from carinata, giving long descriptions. As 

 it is unnecessary to quote these descriptions in full, I give here 

 merely a translation of the diagnoses (p. 159) : — 



" (1). Pronotum with not more than 8-9 yellow transverse 

 lines ; frons, sterna, and pleura yellow ; base of abdomen (ventral 

 aspect) blackish ; ' legs ' [' benen ' = (I think) posterior tibiae and 

 tarsi] pale yellow. 1. variegata. 



"(2). Pronotum with 10-12 yellow transverse lines; frons 

 darker or paler brown ; sterna and pleura black, with pale 

 margins ; abdomen brownish, with pale margins ; at least the 

 exterior margins of the ' legs' brown. 2. carinata." 



At the end of the description of the former he adds : — 



" Obs. Saunders regards this as identical with the following, 

 from which, however, it may at once be differentiated by the 

 smaller size, smaller number of yellow lines on the pronotum, 

 and shorter pronotal carina, the paler colour underneath, the 

 yellow design of the elytra, which is more extended and more 

 obscurely (ptydligare) divided into series, and lastly by the form 

 of the anterior tarsi in the male ; the extension farther back- 

 wards of the frontal fovea* of the latter forms another difference. 

 Douglas, to whom I sent an original example, .... has pro- 

 nounced his C. intricate identical with our species. It is similar 

 also to Fieber's germari, but the latter is larger, the frontal fovea 

 of the male extends scarcely beyond the angle of the eyes, 

 sterna and pleura are blackish," &c. 



The pronotal lines in both intricate and sharpi are much 

 split, especially those in the centre, and it is not easy, if possible 

 indeed, to state exactly how many lines there are ; moreover, 

 White's single male of intricate has certainly not less than eleven 

 of these lines, and after a careful examination I cannot see any 

 noteworthy difference in this respect between his sharpi and 

 intricate. Moreover, Fieber (Abhandl., p. 250) states "lineis 

 9-10 nigris " in the diagnosis of gcrmarii, and " lineis . . . 8-9 



* My rendering of this sentence is very free, but it is the only meaning I can 

 gather from "hvarjiimte uppehallsorten synes vara en annan."
