Subfamily IX. ECTRICHODIIN.E. 



Ectricliodiina, Stdl, En. Hem. iv, p. 4 (1874). 



This subfamily is easily recognized by the structure of the 

 scutellum, which has its apex broad, and with two, sometimes 

 three, apical spinous angulations. 



It is widely distributed, except in the Palsearctic Region, where 

 it appears to be found only in the extreme eastern province ; there 

 are not very many Nearctic representatives, and the Ectricliodiinse 

 are mainly tropical insects. 



Si/nopsis of Genera. 



The primary character for dividing the genera in this subfamily 

 is found in the number of joints of the antennae. Two genera, 

 Antiopula, Stal, and Qaercetanus, Dist., are only represented by 

 specimens in which these fragile organs are imperfect. They 

 must therefore be left out of this synopsis for the present ; but 

 both genera are easily recognized by other characters, and figures 

 are given of both. 



A. Antennae with eight joints. 



a. Scutellum Avitli two apical spinous 



angulations. 



a. Rostrum with first joint longer than 



remaining joints together. 

 a' . Head long, about as long as ante- 

 rior femora. 

 (r. Connexivura witli its margin 



even, not spiued Audernacus, p. 306. 



V . Head not prominently elongated. 

 b-. Connexivum with basal seg- 

 ment spinously produced . . Bayerus, p. 307. 



b. Rostrum with first joint about as 



long as remaining joints together . Scadra, p. 308. 



b. Scutellum with three apical spinous 



angidations, the middle one minute . Ectrychotes, p. 314. 



B. Antennae with seven joints. 

 a. Anterior femora unarmed. 



a. Antennae with first joint about as 



long as head ; eyes not unusually 



prominent Mendis, p. 312. 



b. Antennae Avitli first joint much 



longer than head ; eyes exceedingly 



prominent Libavius, p. 313.
