and Dryops strigipennis, Wh. (‘‘Ereb. and Terror," p. 12), belong to Sessinia. 
The genus is differentiated from Nacerdes by its two-spurred tibim. Seleno- 
palpus chalybeus and subviridis are probably only varieties of S. cyaneus, Fab. 
(Dryops ). 
Mordella funerea. 
M. nigra, subtillissime squamulosa, elytris in medio maculis duabus 
fasciaque flexuosa postica, ad suturam interrupta, albo-pubescentibus, 
sed in certa luce evanescentibus ; antennis, articulis quatuor basali- 
bus exceptis, serratis; capitis fronte subtillissime punctata; tibiis 
fere ecalearatis; tarsis quatuor anterioribus breviusculis ; aculeo 
paulo recurvo ; corpore infra nitido nigro. Long. 7 lin. 
Hab. : Waikato. 
About the size and general appearance of the Australian M. 10-maculata, 
Fab., but, inter alia, minutely scaly, except the white spots and band, not 
“pubescent, and the tibial spurs nearly obsolete. 
Mordella detracta. 
M. nigra, pube, in certa luce grisea, subtiliter vestita; elytris fascia 
flexuosa ante medium maculisque duabus posticis albis ornatis ; 
antennis minus serratis; capite antice valde convexo; tarsis quatuor 
anterioribus valde elongatis; aculeo recto, breviusculo ; corpore infra 
griseo-sericante. Long. 4 lin. 
Hab.: Waikato. 
About the size and general appearance of our M. fasciata, but the elytra 
narrowing much more posteriorly and differently marked. 
i IrENIMUs. 
Rostrum parum elongatum, modice robustum, versus apicem manifeste 
crassius, apice triangulariter emarginato ; scrobes breves apicales: 
Antenne graciles; scapus prothoracem attingens ; funiculus articulo 
primo vix incrassato ; clava distincta. Oculi subtenuiter granulati. 
Prothorax subcylindricus, basi rotundatus, lobis ocularibus parum 
prominulis. Elytra elongato-cordata, basi prothorace manifeste 
latiora, humeris obliquis. Femora crassa; tibie flexuose, posticse 
corbellis subeavernosis. Abdomen segmentis duobus basalibus ampli- 
atis. Corpus squamosum. 
Allied to the Australian genus Perperus, differing principally in the base 
of the elytra exceeding the width of the prothorax at the base. This is a 
character on which Lacordaire lays great stress; but in many genera it 
really seems to be only of specific importance. 
Irenimus parillis. 
I. oblongus, niger, squamis obscure cervinis omnino dense tectus, setu- 
lisque nigris adsperus ; rostro capite duplo longiore, antice carinato ;
