A NEW SPECIES OF ORTHOCLADIUS (CHIRONOMIDA, 
DIPTERA). 
By. Rh MALTOCE AU chbanar, Je 
The species described in this paper is the first of the genus 
which I have seen with conspicuously marked wings. 
Orthocladius bifasciatus sp. n—Female: Black. Head, with the excep- 
tion of the eyes, and the thorax glossy; abdomen velvety. Legs whitish 
yellow, blackened on cox, femora except bases, apices of tibie and of 
tarsi. Wings with two broad black fasciz, one before and the other just 
beyond middle, which are connected along costa by a fuscous streak, and 
more or less distinctly connected in middle between cubitus and media; 
subapical fascia narrowed posteriorly, not reaching margin of wing. Hal- 
teres black. 
_ Antenne fully as long as thorax, surface hairs short. Thorax almost 
nude, center with a slightly depressed line in which is a series of short 
hairs; scutellar hairs short and weak; pronotum very short, linear above, 
and without distinct central incision. Basal joint of fore tarsi not over 
two fifths as long as tibia; empodia distinct but small. Costa ending at 
beginning of apical curve of wing; upper branch of cubitus conspicuously 
undulated, ending closer to media than to lower branch of cubitus. 
Length, 1.5 mm. 
Type locality, Stratford, Ill., June 22, 1917 (J. R. Malloch).

The writer has recently published a revision of the genus 
Lygus,} giving data on the distribution and food plants of the 
species in the United States. During the summer of 1917 it was 
the writer’s good fortune to be a member of the Cornell Biological
