366 Mr. P. Cameron's descriptions of new 



coloration. It is a larger insect than A. pleuralis, the 

 antennae are somewhat longer, and have the 3rd joint 

 longer in proportion to the 4th, and the cubital nervure 

 is not traced in pleuralis at all. 



Hob. New Galloway, in June. 



Allotria curvicomis, n. s. 



Black ; the four or five basal joints of antennae fuscous ; 

 mouth piceous ; legs dull testaceous ; the coxae and 

 femora almost piceous at the base. Wings hyaline ; 

 nervures fuscous. The antennae are longer than the 

 body, being as long as the fore wings ; the 3rd joint is 

 slightly and the 4th and 5th distinctly curved and 

 slightly thickened ; the 6th is very slightly bent, but 

 not so much as the 3rd. The radial cellule is of mode- 

 rate size, longer than broad ; its outer margin is curved ; 

 the cubital nervure is only traced at the base. The 

 pubescence on the metathorax is distinct ; the petiole 

 piceous. Length, If mm. 



Allied to A. longicornis, but differing from it in its 

 shorter radial cellule, somewhat shorter antennae, these 

 in longicornis not having the 4th and 5th joints curved. 



Hob. Glen Lyon, in July. 



Allotria Mullensis, n. s. 



Black ; head dull ferruginous, vertex piceous ; pleura 

 almost piceous ; five basal joints of antennae pale tes- 

 taceous, the rest fuscous ; legs dull testaceous ; coxae and 

 femora fuscous. Two basal joints of antennae enlarged, 

 as long as the 3rd, which is longer than the 4th ; joints 

 3 — 5 thin ; the rest much thicker, becoming thicker 

 towards the apex ; last joint one-half longer than the 

 preceding. Metathorax and coxae covered with a dense 

 white pubescence. Wings hyaline, the base yellowish ; 

 nervures pallid-yellow ; radial cellule closed, minute, 

 almost semicircular, not being much longer than broad ; 

 nervures thick ; cubital nervure shorter than the length 

 of radial cellule ; fringe on apex of wing longish. Male. 

 Length, f mm. 



Comes nearest to A. brcvis, Thorns., but is readily 

 known from it and every species known to me by the 

 shortness of the radial cellule, which differs also in being
