262 ENTOMOLOGICAL NEWS. [June, '06 



ends only, tarsi black ; style green to blackish, short and ensiform ; the 

 honey tubes are long and cylindrical, green at the base and shading 

 into dusky at the ends, or all dusky, their peculiar form as described 

 for alate female below ; beak pale green, dusky at tip, barely reaching 

 3d coxae. 



Measurements about as follows: body, 1.40 mm.; style, .iimm. ; honey 

 tubes, .27mm. ; antenna, .8omm. ; joints III, .17; IV, .13; V, .11; VI, 

 .11; VII, .i8mm. respectively. 



Alate viviparous. ?. 



General color green, head dusky to black, eyes bright red and very 

 prominent, prothorax green with dusky to black transverse band ; 

 mesothorax blackish upon central portion, lateral margins green; ab- 

 domen green ; wings hyaline with distinct, rather conspicuous dark 

 veins, the base green. The abdomen and the head are sometimes mot- 

 tled with light orange ; mesosternum black ; the beak is a very light 

 green, dusky at the end. Along each side of the green abdomen above 

 there often are 4 or 5 small dusky spots which do not show in all speci- 

 mens; style ensiform and .n mm. long. Antennae about 1.06 mm. long, 

 green at base and blackish beyond the middle of joint 3; 3d joint 

 with about 12 sensoria, 4th with about 8, 5th with one large sensorium 

 near the distal end and 2 or 3 along the middle portion ; 6th, at the 

 joining of the 7th., with six small and one large sensoria; joints about 

 as follows: III, .27; IV, .17: V, .15: VI, .13; VII, .22 mm. The femora 

 are dusky at outer end or entirely light green, tibiae dusky to black at 

 distal ends, tarsi black, cornicles dusky greenish yellow throughout, 

 cylindrical. 



Length of body 1.30 mm.; wing, 2.13 mm.; stigma .60 mm.; narrow 

 and parallel-sided; cauda .11 mm. dusky brown in color. 



The very broad head and very prominent compound eyes are 

 striking peculiarities in this species. The cornicles which would 

 be classed as cylindrical are somewhat constricted immediately 

 back of the slight flange, then comes a slight enlargment from 

 which the cornicle very gradually diminishes in diameter to the 

 base. 



During my study of this insect as a student in entomology 

 at the Colorado Agricultural College during the winter and 

 spring of 1906 and 7, I did not find it upon any plants but the 

 chrysanthemums. It seems to be strictly a greenhouse species 

 at Fort Collins, as neither Prof, Gillette nor any of his assis- 

 tants have found it upon out of door plants.
