BLENNOCAMPA. 



Blennocampa, Htg. Blattw. p. 266 (1837). 



This genus is limited to those species which have no middle cellules in the posterior 

 wings. It contains fewer species than Monophadnus, and is also somewhat more limited 

 in distribution. Twenty-five European species are known ; two have been described 

 from Asia Minor, seven from North America, and five from South America (namely 

 one from Brazil allied to B. subccerulea, two from Para, and two from Chili). 



1. Blennocampa albofemoralis. (Tab. II. figg. 12, $ ; 12 a, head.) 



Nigra, pilosa, mesonoto (scutello excepto) tegulisque runs ; metapleuris, coxis, femoribus, tibiarum basi, tarsis, 



ore pronotoque albis ; alis violaceis ; antennis pilosis. 

 Long. 8-9 millim. 



Hdb. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



The antennae are as long as the abdomen, the third joint thinner at the base, longer 

 than the fourth, the last four joints abruptly shorter. Sutures on the vertex deep ; 

 central ocellus surrounded by a wide and deep furrow. Two lateral fovese large ; a 

 tubercle in the centre, not united with the central fovea, which is small. The trans- 

 verse radial nervure is received at the edge of the apical third of the cellule ; transverse 

 median a little in front of the middle, the first recurrent nervure is received close to the 

 middle of the cellule ; third cubital cellule much longer than the second ; there is a horny 

 point at its base ; and there is another in the second. In the hind wing is a long appen- 

 dicular cellule. Claws subbifid ; the clypeus is rounded at the edges, truncated in 

 front ; labrum rounded. The clypeus, labrum, and a little space between the antennae 

 white ; mandibles black. Palpi white, black at the apex. The metatarsus is as long 

 as the four succeeding joints ; tarsi as long as the tibiae; the apical joints of tarsi black. 

 The abdomen is longer than the head and thorax ; the blotch is very large, white ; apex 

 of the abdomen and sheath covered with long hairs. 



2. Blennocampa sumichrasti. 



Selandria sumichrasti, Norton, Trans. Amer. Ent. Soc. iv. p. 82 ; Cresson, loc. cit. viii. p. 40, ? \

3. Blennocampa intermedia. (Tab. II. figg. 11, ? : a, head ; b, tarsus ; 

 c, antenna.) 



Nigra, pronoto, tegulis mesonotoque rufis ; antennis pilosis ; alis violaceis, nervo 2° recurrente interstitiali. 

 Long. 8 millim. • ' ' 



Hal. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



The antennae are a little shorter than the abdomen, slightly thickened in the middle, 

 attenuated at the apex, the third joint one half longer than the fourth. Head sharply 

 narrowed behind the eyes ; sutures on the vertex deep ; frontal area forming a rounded 

 furrow behind and in front of the ocellus, but open at the apex. Lateral foveae large,
