as the female of Mallophora analis. I have a male which agrees with his 

 description. The head is black haired ; the thorax yellow above ; hair on 

 scutellum, in front of the wings and in front of the halters is black; the 

 legs black haired, except' the middle tibiae are yellow haired on outer side ; 

 the abdomen has four basal segments yellow, rest black. The superior male 

 appendages are similar to those of D. lata but more swollen below and the 

 outer side only slightly excavate. Length 17 mm. 

 From Texas. 



KEY TO THE NEARCTIC SPECIES OF LEPTOYPHA AND 

 LEPTOSTYLA (HETEROPTERA TINGID^). 



By W. L. McAtee. 



The genera Leptoypha and Leptostyla, both of Stal, belong to 

 that section of the Tingidas in which the rostral sulcus is closed 

 in front and the discoidal and costal areas of the hemelytra, are 

 rarely or never, coelevated, and to the smaller subdivision in 

 which the rostral sulcus is not interrupted by a ridge between 

 the meso- and metasterni. Leptoypha contains species in which 

 the translucent lacy type of structure so characteristic of the fam- 

 ily is greatly obscured except on membrane and on costa in the 

 species that have it e5cpanded; there is no pronotal hood. The 

 first two joints of antenna are short and of about equal length, 

 and the pronotum has a single prominent median ridge, the lat- 

 eral ridges are traceable especially near apex of pronotal exten- 

 sion. The species are very plainly colored, usually being light- 

 brown, more or less dark mottled or pruinose, and with dark 

 callosities. Leptostyla species on the other hand are distinctly 

 lacy; a hood is present, the first antennal joint is three times (or 

 more) as long as the second, and there are three high and thin 

 pronotal carinse. Some of the species of this genus have a dis- 

 tinct color pattern.
