30. Genus ANTHERICOMMA Pierce (1908). 



Name derived from avdkp£ (stalk) + op.pa (eye) = stalked eye. 



Type of genus. — Anthericomma barberi Pierce. 



This genus is confined to America. Hosts unknown. 



The genus is characterized by having the pronotum and prester- 

 num confined to median disks, surrounded on three sides by the 

 mesothorax, which is laterally contiguous to the head. The antennae 

 are seven-jointed, with the last five joints flabellate of graduated 

 length, making the apical slightly the shortest. The tarsi are three- 

 jointed.

 not connected with presternum, projecting about equally into emar- 

 ginations of the head and mesothorax, medianly depressed longitudi- 

 nally and transversely. Mesonotum transverse, anteriorly broadly 

 emarginate for the admission of the pronotum ; transversely depressed 

 near apical margin. Metanotum very long" (Pierce, 1908). Prae- 

 scutum long, wider at base than apex; scutum elongate linear, with 

 oblique ridge to apical corners of praescutum ; scutellum with base and 

 sides rounded and apex transversely truncate; postlumbium linear 

 transverse, very short; postscutellum as long as all the anterior

ovaler Gestalt, ihre Lange betragt 0.13-0.16 mm., die Breite 0.06 mm., die Borsten des 

 letzten (lOten Ringes) sind 0.09 mm., also etwas langer als die halbe Korperlange; 

 ferner fallen noch an der Ventralseite des vorletzten Ringes 3 paar Borstchen auf, von 

 welchen das mittlere Paar iiusserst klein, das darauf folgende etwas grosser ist, wahrend 

 das aussere Paar, welches nahe dem Seitenrande liegt, bei weitemammeistenvorragt; 

 die Borsten desselben sind 0.02 mm. lang. Im ubrigen finden sich an der TJnterseite

 des Kopfes zeigt einen fast runden schwarzen Pigmentfleck, welcher 5 Linsen tragt,
