A NEW GENUS OF MIRIDAE (HEM. HET.) FROM JAVA.

In Tijdschrift voor Entomologie 1913, Suppl., p. 100—171, tlie late 

 Dr. B. POPPIUS has published a list of the Miridae known from Java, with 

 descriptions of several new genera and numerous new species. Only one 

 species, Laemocoris javanus BREDD., was overlooked by POPPIUS. Since that 

 time only two more Javanese Miridae, Hyalopeplus smaragdinns ROEPKE 

 and Bromeliomiris bicolor SCHUM., have been described. The number of 

 species of this family hitherto known from Java is 77, apparently only a 

 small part of the number actually living in this island. 



Dr. R. Menzel, zoologist at the Theeproefstation of Buitenzorg, has 

 recently sent me for determination a Mirid from Java that, although coming 

 near to Eucerocoris Westw., must be regarded as generically distinct from 

 it. A satisfactory comparison with Eucerocoris is difficult or impossible, 

 as no other generic description of it than the short and inadequate one 

 of Westwood has ever been published, and as it seems rather uncertain 

 whether all the species referred to that genus by later authors really are 

 congeneric with the type and with each other. The rostrum in the typical 

 species is described as extended to the base of the hind coxae, and it is 

 not much shorter in E. suspectus DiST. and E. Thetis KiRK., whereas 

 it only reaches the fore coxae in E. braconoides WALK., basifer WALK, 

 and tumidiceps HORV. hi Westwood's figure of the type the base of the 

 pronotum is represented as rather deeply arcuately sinuate, but it is straight 

 at least in E. Horvathi POPP. The habitat of the type E. nigriceps WESTW., 

 was unknown, and WESTWOOD conjectured "from its general appearance" 

 that it was from Brazil, but I think there can be little doubt that it is an 

 inhabitant of the Australian region, like the other species referred to the genus. 



Arthriticus n. gen. 



Body elongate, impunctate. Head seen from above broader than long, broadly 

 rounded before the eyes, seen from before broader than high, seen in profile somewhat 

 longer than high at the base, eyes removed from apex of pronotum, seen from the side 

 subobliquely oval, postocular part shorter than the horizontal diameter of the eyes, 

 narrowed from the eyes to the base, vertex about three times broader than an eye, 

 immarginate behind, somewhat convex but with a transverse oval shallow impression 

 in the middle, frons and clypeus strongly declivous, almost perpendicular, the latter
