Genus XXX.— CHERMES, Linn.* 



Tannenlaus. 



Rostrum very short and stout. The setae prolonged 

 sometimes twice or thrice the length of the whole 

 insect. 



Antennae short, stout, five-jointed, and terminated 

 by a minute button usually furnished with bristles. 

 The third, fourth, and fifth joints nearly equal. The 

 first and second shorter. 



Cornicles wanting. 



Head and prothorax disproportionately developed. 

 Fore wings broad. Costa rounded. Cubitus stout 

 and terminated by a broad stigma, which by encroach- 

 ment on the cubital cell shows some approximation 

 to the semi-coriacous texture of the Hemiptera Hete- 

 roptera. The fore wing has one stigmatic and two 

 simple non-furcated oblique veins. The hind wings 

 have a single oblique vein. The oblique veins of the 

 upper wing sometimes do not anastomose with the 

 cubitus, but spring from a continuation of the stig- 

 matic vein, which runs for a certain distance parallel 

 to and below the cubitus. 



This characteristic led Koch to divide Chermes, and 

 to describe the insects having this last peculiarity under 

 a new genus Anisophleba ; but I have hesitated thus 

 to split up the genus, for I am not clear that this con- 

 formation is constant in any species. 



The males of Chermes have been slightly noted by 

 Kaltenbach, Ratzeburg, and Koch, and described as 



* Chermes or Kermes, probably from the Arabic or Hebrew Tp"]j?.
