NOTES ON THE SYSTEMATIC POSITION OF THE 

 GENUS EUMENOTUS, WITH DESCRIP- 

 TION OF A NEW SPECIES 



{Hemiptera, Aradidae) 



By TEISO ESAKI 



The oriental genus of the Aradidae, Bumenotus, Westwood, 

 hitherto including a single species, is one of the most remark- 

 able genera of the family from the taxonomic point of view. 

 This genus has been studied by several entomologists, some of 

 whom considered it to belong to the subfamily Aradinae, while 

 others referred it to the Mezirinae. These two subfamilies are 

 well defined from one another, however. During my collecting 

 trip to Formosa last year I captured a specimen of Eumenotus, 

 which seems to represent a second and new species of the genus. 

 After a careful study of this specimen I was led to conclude 

 that this genus is sufficiently different from other genera of the 

 Aradidae to be separated under a new subfamily. 



EUMENOTINAE. new subfamily 



Body moderately thick, very convex beneath. Head much 

 broader than long, bilol^ed anteriorly, and with a distinct pro- 

 jection in front of eye ; no projection behind the eye. Rostrum 

 almost reaching the intermediate coxae. Antenna arising from 

 the latero-ventral part of the anterior lobe. Pronotum broadest 

 posteriorly, not divided into separate lobes. Scutellum very 

 distinct, tongue-like in shape. Hemielytra complete; corium 

 short, being as short as scutellum ; membrane distinct, with well 

 defined veins. Trochanters connate with femora. Sternum 

 sulcate. Abdominal spiracles located near the basal margin of 

 each segment.
