NEW SPECIES OF PLATYLYGUS WITH A NOTE ON THE 
MALE OF LARGIDEA GROSSA VAN DUZEE 
(HEMIP. MIRIDZ).* 
By Harry H. Kwnicut, Ithaca, N. Y. 
Platylygus luridus (Reuter)—This species was first named 
by Reuter-as a variety of Lygidea rubecula Uhl. from a specimen 
collected by Mr. Van Duzee at Lake Placid, New York. It not - 
only represented a good species but was later described as the 
type of a new genus, Platylygus Van Duzee (1915). The writer 
has seen the type specimen and the figures of the male genitalia 
shown here (Fig. 1) are from a specimen collected by G. P. Engel- 
hardt, July 10, Claremont, New Hampshire. The writer finds in 
an investigation of four species that the male genital claspers and 
the chitinous tip of the penis give specific differences, at the same 
time showing a close generic relationship. Only one specimen of 
luridus was available for dissection, the tip of the penis being dis- 
carded before it was noted that the other species showed specific 
differences in this organ, hence the lack of a drawing. f 
Platylygus intermedius new species.—Slightly smaller and more slender 
than luridus, more uniformly translucent yellowish brown, the genital 
claspers and chitinous tip of the penis distinctive of the species. 
6. Length6.8mm., width257mm. Structurally very similar to luridus, 
differing chiefly in the male genitalia and in being more slender and yel- 
lowish translucent in color, the cuneus and cell veins without reddish. 
Embolium and cuneus translucent, tinged with greenish yellow; last two 
segments of the antennz arid the’ tip of the second lightly infuscated; 
sides of the venter tinged with reddish, the genital claspers and chitinous 
tip of the penis (Fig. 2) distinctive of the species. 
9. Very similar to the male in coloration and only slightly more robust. 
The specimens were collected in company with grandis, both occurring 
on the two most common species of pine growing at the top of Mt. Lemon, 
In the series taken no tendency is shown to vary in size or coloration 
toward either grandis or luridus. 
Holotype: 3, July 26, 1917, Mt. Lemon, altitude 9,000 feet, Santa Cata- 
lina Mountains, Arizona (H. H. Knight); Cornell University Collection. 
Allotype: Taken with the type. 
Paratypes: 19 3, 23 °, taken with the types.
