least of the abdomen above, the breast and the coxae more or less spotted or 

 striped with black ... zaddachi, Knw.* 



— Wings not clouded (they may, however, have a tinge of yellow) 3. 



3. Abdomen with a noticeable, though short, grey pubescence, its surface some- 



what opaque. Colour in dry specimens much like zaddachi, but rather 

 darker (J with black tegulse, ? with the mesospleurae edged with black, &c.). 

 (In life, however, the ground-colour of the ? abdomen is green, that of the 

 head and thorax rufescent) turgidusy Zadd.f 



— Abdomen shining ; not noticeably pubescent 4. 



4. (J with red tegulse, ? with mesonotum striped or spotted with black on a pale 



ground 5. 



— (? with black tegulse, ? with mesonotum and scutellum practically all black... 7. 



5. ^ abdomen orange-red (without black ; except on the propodeum and the ex- 



treme base of the following segment) ; ? ground-colour bright orange with 

 less black than in any other species (in my specimens the abdomen is 

 practically immaculate, but Konow says it may be banded above with brown)... 



Jlaviveniris, Htg. 

 (? turgidus, C). 



— (? abdomen above mostly black, ^ brownish-yellow or whitish (not bright orange), 



with extensive black markings above 6. 



6. Vertical area broader, with a deep central longitudinal sulcus. Stigma yellow. 



J with head less narrowed, and antennae more compressed. 9 with abdomen 



quite pale beneath trisignatus, Foerst. J 



{caprese, C). 



— Vertical area narrower, hardly sulcate centrally. Stigma white (at least in $ ). 



(J very like the last species, but the head is more narrowed behind the eyes, 

 the antennae less compressed, &c., $ with a paler (more whitish) ground- 

 colour than trisignatus, but a greater extension of black, and the abdomen 

 beneath is not wholly pale. (Generally speaking this is a smaller and 



blacker looking insect than trisignatus) clitellatus, Lep.§ 



(imperfectus, C). 



7. (? antennae as long as the body, ? head widened behind with pale tempora. 



(A large and easily recognisable species, 7 — 9 mill. long)... 



xanthocarpus, Htg. 

 {thomsoni, C, clibrichellus, C). 



* This species = umbripennis, Zadd. (nee Bversm.), Konow records it as known to him from 

 England. I have only foreign specimens of it myself, and it is not known seemingly as British 

 to Mr. Cameron. 



t Konow ha.s abandoned his former identification of this .species with brachyolus, Forst. 

 Turgidux, C, acco'rding to Konow, is not this species, but the next. 



X Tliis is generally known as caprert ; but according to Konow the original caprect of L. was 

 a Pteronus. The whole synonymy of this group is so perplexed, that I do not pretend to have 

 any views of my own alwut it, and merely reproduce those which are expressed in Konow's 

 latest works. 



§ CliteUatus, till lately, was called by Konow einersbergensit, Htg. The name imperfectus, 

 Zadd., is assigned by him to a different species, not of this group, and (as far as I know) not 

 British.
