separate it from the Eunienidse, and tlie form of the claws prevents 

 it from being placed in the Vespidae, as well as the fact that the 2nd 

 cubital cellule does not receive both the recurrent nervures, which 

 is always the case with the Vespidae. I have not ventured to ex- 

 ti'act the mouth organs in order to make an exact examinaticm of 

 the palpi ; but I can make out with certainty the fact that there are 

 at least 5 joints in the maxillary and 4 in the labial palpi. The 

 genus differs from the typical Masaridae in having 3 closed cubital 

 cellules, and in the recurrent nervures being received in different 

 cellules, in which respect it agrees with the genus Euparagia Cres- 

 son, from which it may be known, inter alia, by the distinctly ap- 

 pendiculated radial cellule. In the latter respect it agrees w^ith 

 Qaartinia, but that genus otherwise is a typical form of Masaridse. 

 The Masaridae, as defined by de Saussure and other writers, have only 

 two closed cubital cellules, so that if the present genus and Euparagia 

 are to be included in it, the definition will have to be altered, so far 

 as the number of the cubital cellules is concerned. 



Paramaifaris fuscipeuuis sp. uov. 



Black, covered with a white pile; the under side of the antennae brownish, the 

 apex of the petiole and of the second segment pallid yellow; the wings fuseo- 

 hyaliue ; the radial cellule smoky ; the stigma and nervures black. 9 • Long : 

 7 mm. 



Antennfe shorter than the thorax ; the joints of the club clearly separated, the 

 thickening commences from the 4th joint. The front, vertex and the upper part 

 of the eye incision distinctly punctured ; the clypeus is shining and less strongly 

 and closely punctured ; its apex is distinctly depressed and the sides are roundly 

 narrowed. The sides of the thorax are more densely covered with a silvery pile 

 than the upper part; the pro- and mesothorax are closely and distinctly punc- 

 tured ; on the apex of the mesonotum, in the centre, are two short deep furrows, 

 which are deep and are wider at the apex than at the base. The scutellum is 

 more strongly and somewhat more widely punctured ; its basal furrow bears 7 

 stout longitudinal keels. The median segment, except on the base and the lower 

 part of the pleurae, bears large, round, deep punctures; the centre in the apex is 

 smooth, shining and depressed ; down the middle of the segment is a narrow, 

 transversely striated band ; the transverse striae being weaker at the base, and at 

 the apex they are stouter and fewer in number. The base of the protborax is 

 keeled all round; behind this keel is another less distinct one, which curves 

 backwards above to near the end of the pronotuni; on the pleurae the space be- 

 tween the two keels is striated. Mesopleurae obscurely and sparsely punctured ; 

 in front of the centre are 7 large foveae, the upper 4 are round and deep and the 

 uppermost is in front of the others; the lower ones are larger and deeper, are 

 separated by stout keels, and are placed more in front of those in the middle so 

 that the row of fovea; forms a curve ; the apex is bordered by a narrow creunla- 

 ted furrow. On the lower half of the base of the metapleurae are four deep
