INSECTS OF SAMOA. 



non-carinate lateral margins of pronotum, it resembles the MyodocHni. The 

 short tooth-like ridge on lateral margin of posterior lobe above humeral angle 

 and the carinate lateral margins of the juga distinguish it at once from all other 

 genera of both these groups. It has been temporarily referred to the Rhyparo- 

 chrominae, near Ozophora Uhl. 



40. Bryanella longicornls, sp. n. (Text-fig, 20). 



Colour. — Head fuscous, eyes ferruginous, ocelli red ; antennae yellow, 

 fourth segment ferruginous brown ; rostrum yellow with its apex black. 

 Anterior pronotal collar fulvous yellow, anterior lobe fuscous, posterior lobe 

 fulvou,^. yellow with posterior lateral ridges and jjunctures fuscous. Scutellum 

 fuscous with a median longitudinal stripe on posterior third, fulvous shading to 

 yellow at apex. Pro- meso- and meta-pleura, fuscous, the acetabulae and the 

 posterior margins of the metapleura, fulvous. Hemielytra pallid yellow more 

 or less suffused or dappled with fulvous brown, the costal margin pallid with a 

 dark fulvous broAvn spot on a level Avitli apex of clavus and another at apex of 

 corium ; ajDical third of clavus in some specimens also brown. Membrane 

 opaque infumate, a longitudinal spot below the aj)ex of corium a spot at apex 

 of clavus and the apical area pallid and semi-hyaline. Legs bright yellow ; 

 coxae ferruginous ; aj^ical halves of femora slightly fulvous, apices of tarsi and 

 claws brown. Venter shining ferruginous brown. 



Structure. — Vertex finely but distinctly punctate, a V-shaped area with its 

 base at the inter-ocellar pit and an area on each side between ocellus and eye, 

 smooth impunctate ; upper surface of head rather sparsely covered with pale 

 depressed hairs and very sparsely with long erect dark hairs ; relative lengths 

 of antennal segments, 18 : 44 : 33 : 30 ; last segment fusiform. Anterior lobe 

 of pronotum finely punctate around the smooth dull cicatricial areas, with a 

 certain amount of white pruinosity ; posterior lobe more coarsely punctate ; 

 whole pronotum covered sparsely with long erect dark hairs. Scutellum more 

 or less regularly punctate, the median longitudinal fulvous strijie on apical third, 

 laevigate ; disc with several long erect dark hairs, sometimes with definite 

 patches of white pruinosity. Pro-, meso- and meta-pleura finely and more or 

 less regularly punctate ; posterior margin of metapleuron impunctate, separated 

 from rest of pleuron by a deep transverse strongly punctate linear impression. 

 Hemiel}d3ra sparsely covered with long erect hairs ; clavus with two distinct 

 lines of punctures, the area between irregularly punctate ; corium with a dis-
