82 APPLE LEAVES SIGNOREt's GOLDEN-EYE. 



the antennae inserted close together, they are separated at their 

 bases, and a cylindrical protube;anc s or horn projects from the 

 front between them. For this genus I propose the name J\Iclcoma T 

 formed from two greek words, implying bad smell, in allusion to 

 the odor which in common with several species of Chrysopa, these 

 insects exhale. But one species is known to me, which may be 

 named and described as follows : 



Signoret's GOLDEST-EYED Fi.y , (Mtkoma Signarelti} is of a pale yellowish 

 green color, and is clothed with a fine short pubescence, especially upon the 

 abdomen. The cylindrical horn which arises between the base of the antennae 

 is longer than broad, and is directed forward upon a line with 'the head and 

 thorax. It is a third longer and somewhat thicker than the enlarged basa* 

 joints of the antennae, is slightly dilated at its anterior end, where \Hs abruptly 

 turned downwards almost at a right angle, this deflected part forming a thin 

 transverse lamina of a light yellow color, vertically striated on its anterior 

 face, and with a projecting acute tooth in the middle of its lower margin, which 

 is of a brown color and turned backwards. Upon the top of tlic head is a 

 transverse elevation, with a deep excavation immediately back of it. The face 

 has a round smooth elevated brown spot upon each side of its centre. The 

 antennae are very pale brownish, the two basal joints light green. The basal 

 edge of the anterior segment of the thorax is elevated, and there is a more 

 prominent obtuse elevation forward of this, separated from the base by an in- 

 tervening transverse groove. The basal elevation shows a longitudinal im- 

 pressed line on its middle, and back of this a more strongly impressed line 

 extends across the middle of the anterior elevated lobe of the second segment. 

 The legs are whitish, the feet tinged with dull yellow, with black hooks at 

 their tips. The wings are slightly angulated at their tips, the hind pair more 

 conspicuously so. They are hyaline and glass-like, with a slight opacity at 

 the stigmas or that part of the wing which is forward of the extremity of the 

 outer margin. Their veins and veinlets are whitish except the two subapical 

 scries of veinlets of the anterior pair, and tho.se which are given off along the 

 inner side of the rib-vein, which are brownish black. This species measures 

 1.15 across the wings when spread. It was captured the latter part of July, 

 near the summit of Mount Antonio, one of the outliers of the Green Mountain 

 range, slightly beyond the boundary of our State, in Rupert, Vermont. I 

 name it in honor of my valued friend, Dr. Signoret, of Paris, whose elegant 

 Iconograph of the Tetligoniides now publishing in the Annals of the Entomo- 

 logical Society as well as his previous productions, are an enduring monument 

 of the extent and accuracy of his researches in that branch of the science to 

 which he devotes himself. 



The sp( cies of the genus Ciirysopa are all of a bright pale green 

 or yellowish co'.or; tl e number and situation of the veins and 

 veinlets or short connecting veins in their wings, is the same, 

 and they differ but 1 ttle in size. To the naked eye they seem to 

 form but a single species. I had long noticed that individuals of
