Rah.: Japan, Kurigaliara (Leiins). 



Two specimens, assumed to be c? a-nd ? , the latter with the inter- 

 mediate lei^s considerably elongated. Near the European A. fvsnda 

 Redt., but more narrowed anteriorly and posteriorly, and with the 

 antennal joints -i-10 broader than long. The J^. American A. glaucula 

 Lee., is a much smoother insect. 



Abdera Steph. 



In Lewis's Japanese collection there is a species allied to the 

 European J., tr'ujutiata Gyll., his A. scriptipennis belonging to Carida. 

 The Califomian Hypulus (Dircaea) bicinctns Horn, a specimen of which 

 from Lake Eleanor. Yosemite (captured by my son in Jidy, 1915). is 

 before me, is an Ahdera. nearly i-elated to A. qtiadrifaaciafa Steph. ; 

 the genus, therefore, is an addition to the American list. Spilotus 

 Lee., type 4!-pustnJatus Melsh., is very similar to these insects, but it 

 has a long, cultriforin. apical joint to the maxillary palpi. 



1. — Abdera trisignata, n. sp. 



Oblong, convex, shining ; pale testaceous, the head (the mouth parts and 

 palpi excepted), the antennal joints 3-11. the prothorax with a transverse 

 fascia on the disc (in one specimen divided down the middle, and in another so 

 extended as to leave the miirgins only pale), the elytra with a common, transverse 

 or triangular, patch at the base and an angulate median fascia (of variable 

 extent and not reaching the sutui-e). and the under-surface in part, piceous or 

 nigro-piceous, the femora and tibitie sometimes slightly infiiscate ; closely, the 

 elytra rather coarsely, punctate, clothed with long, decumbent, pallid hairs, 

 with scattered erect hairs intermixed. Antennae slender, joint 3 a little longer 

 than '1 or -l-, 4-10 obconic, longer than broad in $, shorter in ? , 11 slightly 

 longer than 10. Eyes small. Terminal joint of maxillary palpi ovate, obliquely 

 ti'uncate. Prothorax short, nearly as wide as the elytra, margined at the sides 

 posteriorly and at the base, ai-cuately narrowed anteriorly, the hind angles 

 rounded. Elyti-a compai-atively short. Legs slender ; posterior tarsi with joint 

 1 as long as 2— t united. Length 2-i\5-2|, breadth 1-1| mm. 



Hob. : Japan, Nikko and Kioto {Lewis : vi and viii, 1881). 



Three specimens, varying in the development of the dark markings, 

 one with longer antennae assumed to be (^ . Shorter and broader than 

 the European ^4. trujuttata GylL, the prothoi-ax nearly as wide as the 

 elytra, the latter less parallel- sided, the antennae more slender, the 

 markings ditt'ei-ent. Both species belong to the sub-genus Caridina 

 Seidl.* A. trigiittata lives in fungoid growth under the bark of pines.
