48 Rev. F. D. Morice on male terminal segments and 



apex to the stipes. As E,adoszkowski has no species 

 called caspicus in his Revision, while Morawitz, as we 

 have seen, knew thoroughly both species, I feel practically- 

 certain that Radoszkowski dissected ^easincusnoi knowing 

 it to be such, and wrongly assigned it to hyl mform,is. 

 And what he called floralis was probably another specimen 

 of the saine insect, indeed he himself suggests this as prob- 

 able. (The true Jioralis seems, from what both Evers- 

 mann and Morawitz say of it, to have been very different 

 from either casjoieus or hylxiformis, and very likely did 

 not belong to the group of unnotchcd stipites at all. But 

 what it was, I have no idea. It must be a very small 

 insect : 7-8 mill. sec. Morawitz.) Therefore, I think 

 hylcxiformis, Rad. {ncc. Eversm., nee. Moraw.) is a synonym 

 of caspiens, Morawitz. 



Several of Radoszkowski's figures might possibly be 

 referred to the true hylseiformis, e. g. his aneeps, mixta, 

 and carinatet, are all more or less suggestive of it. 



I never took hyliBiformis myself, but have met with 

 caspiens in several Mediterranean countries, and received it 

 from others and also from Transcaucasia. It seems to be 

 widely distributed, therefore, and probably is one of the 

 common species of its group. Prof. Perez takes it at 

 Royau, near Bordeaux. 



The sagitti3e of hylxiformis and caspleus seem very 

 similar. Their most striking character is perhaps the 

 large tooth-like fold of sub-opaque (but not thoroughly 

 chitinized) substance which spreads out from them near 

 the bases, overlying and partly hiding the base of the 

 more transparent " wing." Above this fold is another 

 dilatation of the sagitta, less conspicuous in the dorsal 

 aspect because seen only in profile, but also looking denti- 

 form Avhen viewed laterally. This is more solid — in fact 

 it is completely chitinized and black. It appears to cor- 

 respond, though its situation is very different, to the 

 triangular dilatations at the bend of the sagittse in 

 halteatus, etc. 



In both species the lobes of the seventh ventral plate 

 spring from short broad bases — not elongate petioles. In 

 most of my specimens the outer apical corners are curled 

 or rather creased diagonally into a sort of "dog's-ear," and 

 when this happens the segment assumes an outline which 

 always reminds me of a bishop's mitre as represented in 

 heraldry. As compared with ligatus the lobes are more
