2. — Aurantiacus = antennatus, C. (olim). Of this in vol. iv Mr. 

 Cameron says " Konow is no doubt right in sinking this as a synonym 

 of aurantiacus, Htg." 



Tn Konow's Catalogue (1890) aurantiacus, Htg. (with antennatus, 

 C, as a synonvm) was given as a Nematus ; but since (in 1900) and 

 again in the Eevision of Pontania, Konow has adopted another view 

 of aurantiaciLS, Htg , and now regards it as a Vantania (viz., hipartita, 

 Lep.). He also quotes aurantiacus, C, as a synonym of bipartifa, 

 Lep., referring however, T suppose, not to the, aurantiacus = antennatus 

 of Cam., vol. iv, but to another species described in Cam., vol. ii, under 

 the name of aurantiacus, Htg. T cannot make out from vol. iv to 

 which of Konow's genera Mr. Cameron considers the latter species to 

 belong ; he only says " it is not aurantiacus, Htg," but gives no further 

 characters nor reasons for his change of opinion. 



A^ to antennatus, Q.,\t is said to have the stigma "testaceous 

 with a black base, which looks as though it were a true Nematus. But 

 its other characters by no means suggest that genus, e. g., clypeus 

 "transverse" (in opp. to "incised"), 3rd cubital cell "not much 

 longer than broad," &c. It is strange, also, if it be a Nematus, that 

 Mr. Cameron should say nothing whatever about its saw-sheath. 

 "Without information on this point, it seems useless to hazard any 

 conjecture as to the possible affinities of the species. 



3. — Y-fiavum. The various notices of this species in Mr. Came- 

 ron's work are very puzzling and difficult to reconcile. In vol. iv it 

 is treated as a Nematus in Konow's sense, and said to belong "to the 

 group of luteus.'' Tn vol. ii it is described as a member of " the group 

 of hetidce, " and said to be " allied to conjugatus^ The two latter 

 species both belong, however, to Pristiplwra, and neither of them has 

 the slightest similarity to a Nematus sec. Konow, Afterwards, in the 

 same volume, it re-appears in yet another group, coupled with two 

 species of Pteronus and one of PacJiymenatus. 



Not one of the characters by which it is defined is at all suggestive 

 of a true Nematus — the clypeus is called truncate, the stigma uni- 

 colorous, and of the saw-sheath it is only said " not so black and 

 hairy " {i.e., as that of conjuqatus). 



Herr Konow tells me he knows nothing like V-Jlavum as described 

 by Cameron, and altogether I can only leave the riddle of its affinities 

 unsolved. 



On the whole, then, my impression is that w^e cannot claim for 

 the British list any other real Nematus than the four which belong also 

 to the Scandinavian Fauna, viz., ahdominalis (= ventralis, Thoms.), 

 luteus, hilineatus (= hlugii^ Thoms.), and acuminatus.
