1092 COLEOPTERA 



Length, 1 lines; breadth, f line. 



My specimen, minus a leg, came from Mr. Sandager, who, I 

 believe, found it on Mokohinou Island. 



Syncalus. 



1942. S. piciceps, n -s- Ovate-oblong, convex, opaque ; clothed 

 with fine brassy depressed, and with erect fuscous, setae ; head 

 blackish, body rufo-fuscous, thoracic margins rufescent, legs obscure 

 fusco -rufous, tarsi, antennae, and palpi red. 



Head without depressions, covered with rounded granular eleva- 

 tions having a minute puncture in each, the granules much closer 

 and rather smaller in front. Antenna with the second joint about 

 as long as the uncovered portion of the piceous basal joint, third 

 nearly twice as long as the fourth, eighth not half the breadth of 

 the ninth, tenth slightly broader but shorter than the preceding one. 

 Thorax transverse, convex, sides explanate, slightly curved and 

 narrowed towards the front ; its granules rather flat, round or oval, 

 not evenly distributed, so that there are smooth spots, notably near 

 the base, which is depressed at the middle. Elytra oblong, rounded 

 behind, with series of punctures, the two sutural rows much finer 

 than the others, there are no distinct elevations or crests. Tibiae 

 with coarse outstanding setae similar to those along the sides of the 

 body. Prosternum depressed between the front coxae. 



Length, 2f ; breadth, 1-| lines. 



Wellington. One example, found by Mr. Sandager. 



Chorasus. 



Nov. gen. 

 (Sharp; Trans. Ent. Soc., 1882, Part i., p. 79.) 



Corpus subangustatum, haud convexum, nudum. Antenna bre- 

 viusculae, 10-articulatae, articulo primo condito, clava abrupte biar- 

 ticulata. Caput exsertum, oculi canalicula suboculari maxima. 

 Prothorax subtus ad angulos anteriores maxime irnpresso. Proster- 

 num magnum ; coxae minutes, globosae, sat distantes. Metasternum 

 parum elongatum ; coxae intermediae sat distantes, posticae paulo 

 magis distantes. Abdomen ex segmentis quinque subaequalibus 

 composition, suturis profundis. Pedes sat graciles, mutici ; tarsi 

 4-articulati, haud elongati, articulo basali quam 2 paulo longiore, 

 2 et 3 brevibus, 4 quam ceteris paulo longiore. 



The affinities of this little insect with the anomalous European 

 Langelandia are undoubted ; the antennae and head (including, so 

 far as I can see, the parts of the mouth) are extremely similar in 

 the two genera, except that the eyes are totally wanting in Lange- 

 landia, and are present, though extremely reduced in size, in 

 Chorasus. The structure of the undersurface is similar, except that 

 in Chorasus the epipleurae are broad and nearly horizontal, and the 

 ventral segments are comparatively shorter. The tarsi are un- 

 doubtedly four- jointed. The claim of Langelandia to be admitted into 

 the Colydiidce is absolutely confirmed by this most interesting insect.
