brillant. Poitrine et abdomen a ponctuation fine et inégale. Les tibias postérieurs terminés par un 
longue épine rougeatre, ainsi que l’extremité des poils que forment la frange des tarses natatoires de la 
méme paire.” 
This insect, described from an unique female in the collection of Crotch at Cambridge, appears to be 
unknown to me.—D. 8. 
1468. Hyphydrus maculatus, Bab., Tr. Ent. Soc. Lond., IIT, p. 12. South America. 
“ Ovatus, brevis, gibbus, fuscus, capite, thoracis lateribus elytrorumque maculis testaceis, subtus fuscus 
antennis testaceis, pedibus fuscis. L. 2, lat. 14 lin.” i 
“Short, ovate, gibbous, the whole upper surface coarsely punctate. Head testaceous ; in one specimen 
fuscous. Antenne testaceous. Thorax transverse, similar to H. ovatus, fuscous. Elytra ovate, much 
dilated near the middle, the apex rounded, fuscous, except a bilobed spot at the base; the humeral 
angle, the anterior half of the lateral margin, a longitudinal abbreviated line near the centre of the suture, 
one on the middle of the disk connected with a triangular transverse spot on the margin, and two small 
triangula¥ spots connected with this last, and with each other within the apex, which are testaceous. 
Body beneath fuscous, coarsely punctured, very gibbous. Legs fuscous.” 
“ This pretty little insect was obtained at St. Jago.” 
The specimen of this species in the collection of the British Museum, appears to be a species unknown 
to me, belonging to the genus Hyphydrus ; as, however, the other species of Hyphydrus are confined to 
the Old World, I suspect there is some error in the locality given by Babington.—D. S. 
1469. Hyphydrus rufus, Clk., Trans. Ent. Soc. Lond. 1863, p. 423. China. 
“Ovatus, brevis, crassus, corpore supra convexiusculo, valdé punctato, rufo, nigro-lineato ; capite 
anticé marginato, punctato, thorace anticé emarginato, ad latera obliquato (subrotundato) tenué margi- 
nato, ad basin sinuato, et ad medium late angulato, punctato, rufo ad basin plus minus fusco-adumbrato ; 
elytris latis, brevibus, dense et fortiter punctatis, sutura et quatuor lineis nigris, parallelis, aliquando 
obscuris, interdum post medium breviter interruptis ; corpore subtus valdé punctato, rufo; antennis 
pedibusque rufis. Long. corp. 2 lin, ; lat. 14 lin.” 
The type of this species in the collection of the British Museum is apparently a species unknown to 
me, allied to Hydroporus solieri (No. 371) of the genus Hyphoporus.—D. S. 
1470. Ilybius badeni, Wehncke, Berl. Zeit. XV, p. 164. Hamburg. 
‘“¢ Oblongo-ovatus, convexus, supra piceo-zneus, margine brunneo, Long. 5 lin.” 
“ Zur gruppe"mit bogenformigen vorderrande der hinterhiiften, ziemlich breiten, fast dreieckigen seiten- 
fliigeln des metasternums gehdrend und dem I, subzneus am ihulichsten, doch durch eine gewslbtere 
form und die fiirbe unterschieden. Die oberseite ist dunkel erzfarben mit deutlichen fensterflecken, der 
seitenrand des halsschildes der fliigeldecken sowie die ganze unterseite mit den beinen rothbraun.” 
I doubt whether this be distinct from I. subeeneus (No. 783).—D. 8. 
1471. Ilybius kiesenwetteri, Wehncke, Berl. Ent. Zeit. XVI, p. 136. Germany. 
“ Oblongo-ovalis, convexiusculus, ater, elytris guttulis duabus pellucidis. Long. 9 m.m.” 
“Dem IJ. guttiger sehr ahnlich und auch von derselben farbe, doch ist die gestalt etwas kiirzer und 
gewolbter.” 
“ An den hinterfiissen der miénnchen ist die iussere Klaue am ende hakig gebogen wie bei I, ater, 
wihrend dieselbe bei I. guttiger (wie bei obscurus) doppelt so breit als die innere mit abregundeter 
spitze geformt ist.” 
“ Bei Harburg sehr selten,”
