No. 34-] HEMIPTERA OF CONNECTICUT I FULGORIDAE. 43 



Otiocerus Kirby. 



A genus of frail pretty insects remarkable for their strongly 

 compressed foliaceous head, quite extinguishing the front, the 

 lateral carinae of the vertex being greatly developed and contin- 

 uous with those of the front. The division of the second antennal 

 joint into two to four filaments is also peculiar to this genus so 

 far as our fauna is concerned. These antennal filaments are 

 generally shrivelled and tortuous so it is difficult to be sure of their 

 relative lengths but they seem to be about equal. The ocelli are 

 wanting.

Elytra with a fuscous mark at the tip of the clavus, another at 

 base of the membrane, and indications of an oblique vitta along 

 the subapical transverse veins ; fuscous points more variable in 

 size ; length 10 mm francilloni 



6. Elytra with a vitta from the apex of the clavus to the apex of 



the costal margin kirbyii 



Elytra with a vitta from the base of the corium to the apex of the 

 clavus in addition to that found in kirbyii 7 



7. Elytra clear yellowish white, without dots, the vittae sanguinous, 



the apical sending a branch along the sutural margin of the 

 membrane to the middle of the apical margin ; the radial vein 



with a short sanguinous vitta before the middle coquebertii 



Elytra with a few scattering dots, the vittae fuscous 8 



8. Head with a red vitta from the eye to the tip where it ends in a 



short black line ; elytral vittae faint wolfii 



Head with the red vitta below the line of the eye, sometimes 

 obscure ; elytral vittae distinct 9 



9. Elytra beyond the transverse veins largely fuscous with a large 



apical pale spot; fuscous dots few, on the basal half of the 



elytra only signoretii

 small and confined to the apical areoles amyotii

This large sanguinous or dark red form is common in New 

 York state and seems to be distributed throughout the eastern 

 United States and Canada.
