SCOTT— COLEOPTERA, LAMELLICORNIA AND ADEPHAGA 259 



subtilissime crebreque, ad apicem parum fortius, punctulatis, stria submarginali antice 

 valde abbreviate, disco striis tribus integris et duabus incompletis; 2 et 4 et 5 basin attingen- 

 tibus fereque ad apicem continuatis ; 1 et 3 solum ad apicem indicatis, in parte anteriore 

 tote deletis, variabilibus, saepius interruptis, interdum fere obsoletis. Long. corp. circa 5 mm. 



$ tibiis anterioribus ad apicem dilatatis, ad basin curvatis intusque emarginatis, 

 tarsorum anteriorum et mediorum articulis 1 — 3 dilatatis. 



Oblong-oval and depressed : unicolorous, ferruginous, or sometimes much darker, in 

 which case the head and thorax are pitchy-ferruginous and the elytra pitchy. Surface very 

 finely and minutely reticulate. Head extremely finely punctured, on either side towards 

 the eye often more or less impressed and with 2 or 3 small groups of stronger punctures. 

 Thorax with some punctiform stviolae on either side near the base ; this sculpture varies 

 greatly, being sometimes very little developed, in other cases covering an area reaching 

 almost to the front margin, the variation apparently independent of sex (the sculpture 

 being well-developed in some males) : the thorax has also sometimes a slight impression 

 near the base on either side of the middle. Elytra with numerous very fine punctures, 

 more marked towards the apex : submarginal stria ending behind some distance before 

 the apex, and abbreviated in front at about ^ the length of the elytron from the base : 

 disc with 5 striae, but frequently appearing only 3-striate owing to the great reduction 

 of nos. 1 and 3 ; these are present only in the posterior part of the elytron, varying in 

 length, the front end of no. 1 being usually some distance behind the middle of the 

 elytron while that of no. 3 is nearer the middle ; they end behind a little before the apex, 

 and are frequently interrupted in a number of places so that they often consist of a 

 number of separate short lines, and in some cases one of them (especially no. 1) may be 

 almost entirely absent : nos. 2, 4 and 5 are very distinct, starting from the base of the 

 elytron and being continued throughout its length, nos. 2 and 4 being abbreviated a very 

 little befoi-e, and no. 5 some way before, the apex ; no. 5 curves slightly towards the 

 lateral margin just behind the base. Wings examined in 1 male and 1 female, found to 

 be 5 J mm. long, while the length of the elytron is 3f mm. Underside ferruginous, the 

 posterior coxae and first four abdominal segments bearing striolae at the sides, those on 

 the coxae being longitudinal in direction and those on the segments curving inwards 

 towards the middle line. Male characters of the tarsi etc. are given in the diagnosis. 



The habitat of this species is very remarkable. The series before rae consists of 17 

 males and 20 females, all of which, without exception, were found living in the water that 

 collects between the bases of the leaves of certain precinctive species of screw-pine* 

 i^Pandanus), many feet above the ground. They were found only in tlie endemic high 

 damp mountain-forests, in situations where the water between the leaves would never 

 under ordinaiy circumstances dry up. In one case two larvaj, having a quite character- 

 istic Dytiscid facies, were also found between the leaves, showing that in all probability 

 the whole life-cycle takes place in this curious habitat. There was also very frequently 

 found with the Dytiscids another kind of larva, sometimes as much as 20 mm. long, 

 elongated and somewhat depressed, with a smooth dark hard integument, with the body 



* In all cases where there is an exact record of the species of Pandaniis, it is F. lloriiei : but I cannot be 

 certain that a few of the specimens are not from P. sechellarum.
