in the other species of the genus. Genal cones small, not as long as basal width, often 
distinctly shorter, acute at apex, divergent, subhorizontal, not pubescent, contiguous 
:.at base. Antennae shorter than width of head, thick, always black at tip. Thorax 
^smooth, less strongly arched than in preceding species, sometimes faintly alutaceous, 
sometimes striped on dorsum. Forewings thick, not transparent, somewhat punc- 
dulate, narrowly rounded at apex, about two and a half times as long as broad, ptero- 
stigma long and large; first marginal cell about twice as large as second. Hind wing 
^somewhat fumate. Genitalia—male—genitalia similar to flavida; anal valve broad, 
about two-thirds as broad as long, convex on both hind and front margins; forceps 
.as in flavida. Female—genital segment scarcely as long as two preceding ventral 
sclerites, stout, not acuminate.” 
'THREE SPECIES OF ANASA INJURIOUS IN THE NORTH 
(HEMIPTERA, COREIBiE) 
By H. M. Parshley, Smith College 
The common squash-bug, Anasa tristis De Geer, was until recently 
the only species of the genus known to occur in New England. In 
1914 C. W. Johnson reported 1 the occurrence of A. repetita Heidemann 
in Massachusetts, and up to the time of publication of my New Eng¬ 
land list 2 only two additional records came to light. Subsequently 
I called attention to the discovery of the species in large numbers on 
the star-cucumber, which would appear to be its natural food plant in 
this region. 3 Last June I noted repetita feeding on young plants of the 
cultivated cucumber in numbers probably sufficient to have caused some 
injury, if hand picking had not been employed as a preventive measure. 
The case is similar with A. armigera Say, long known as injurious 
in States farther south. In 1914 I met with the first known New 
England example while sweeping underbrush in a woodland near 
Boston and took another in the same spot the following year. 4 In 
the New England list is noticed but one additional capture, at Am¬ 
herst. I have since taken armigera in moderate numbers, feeding on 
the star-cucumber, and early in the present summer I found it at¬ 
tacking the cultivated cucumber in company with repetita. The 
late generation, consisting entirely of armigera , appeared about the 
middle of August on the cultivated cucumber in such numbers as to 
destroy some of the plants. From a single vine sixty specimens were 
collected. 
Thus it appears that repetita and armigera are increasing in numbers 
in this region, with the likelihood that they will become seriously in-
