1335, Hydroglyphus flaviculus, Motsch., Bull. Mose. 1861, I, p. 108. Ceylon. 
““ Elongato-ellipticus, subdepressus, subnitidus, densissime subtiliter punctulatus, rufo-testaceus, elytris 
pallidis, his basi, sutura, utrinque macula postica bifurcata abdomineque nigro-piceis, oculis nigris ; 
thorace valde transverso, utrinque ad basin oblique impresso, lateribus angulisque posticis rectis; elytris 
thoracis latitudine, antice parallelis, ad suturam utrinque profundo unistriatis, stria integra. Long } 1, 
lat. 2 1.”

T cannot form any decided opinion as to the place of this name; it may possibly prove a species of 
Bidessus.—D. S. 
1336. Hydroporomorpha parallela, Bab., Tr. Ent. Soc. TII, 1841, p. 15. pl. 1, f. 3. Brazil. 
“ Oblonga, antice obtusa, postice acuminata, lateribus parallelis, supra rufa, thorace antice et postice 
elytrisque (apice marginibusque exceptis) fuscis; corpore subtus, antennis pedibusque fusco-rufis. 
Long. 2, lat. 3 lin.” 
“ Head short, transverse, rounded in front, with two longitudinal slightly impressed fovez between the 
eyes. Thorax transverse, short, broadly emarginate in front ; the angles acute ; lateral margins rounded ; 
posterior margin straight, very slightly produced in the middle over the scutellum ; dise smooth, with a 
transverse row of punctures in front, and a similar one behind, the latter broadly interrupted in the 
middle ; rufous, with the anterior and posterior margins fuscous, Scutellum small, triangular, transverse, 
fuscous. lytra of the same width as the thorax, oblong, the sides parallel for three-fourths of their 
length, then strongly rounded to the apex, which is acute and prominent ; disc coarsely punctured, with 
one central row of more regular punctures upon each; fuscous, with the exception of the apex and 
external margins, which are rufous. Body beneath, legs and antenne, dull rufous. Hab., Rio de 
Janeiro.” 
This is a species of Celina allied closely to C. longicornis, No. 652.— D. S. 
1337. Hydroporus aberrans, Clk., Tr. Ent. Soc, Lond. third ser. J, p. 426. Java. 
“ Breviter ovatus, latus, parallelus, fortiter punctato-striatus, punctatus, testaceus, rufo-fusco notatus ; 
capite leviter punctato, rufo-fusco ; thorace antice vix emarginato, lateribus rotundatis, basi pene 
transverso, crebre punctato, testaceo, ad medium fusco-adumbrato ; elytris sat latis, fortiter undique striis | 
punctatis octo latis ornatis, punctatis, testaceis, lineis tribus rufo-fuscis 4 basi ad apicem subparallelis ; 
corpore subtus fusco, antennis pedibusque rufo-flavis. Long. corp. lin. 4; lat. lin. 4.” 
“The only example that I have been able to examine of this species is an imperfect one received by 
Mr. Bowring from Java: it presents very sufficient and striking characters ; the form of the insect is 
short and parallel ; the sides of the thorax are much rounded, compressed at the anterior and posterior 
angles ; the elytra are marked by eight deep striw, formed by closely arranged broad punctures ; in 
colour the surface is testaceous, the interstices between the first and second, the third and fourth, the 
fifth and sixth striz being irregularly rufo-testaceous.” . 
The type of this species has been destroyed, I am doubtful to what genus the insect should be 
referred.—D. 8. 
1338. Hydroporus adumbratus, Clk., Ann. Nat. Hist., 1862, p. 183. Mexico. 
“Oblongo-ovalis, punctatus, pubescens; capite fusco, interdum antice rufo-fusco ; thorace flavo, ad 
basin plus minus fusco ; elytris subtiliter punctatis subpubescentibus, fuscis ; antennis pedibusque rufo- 
flavis. J.ong. corp. 4 lin., lat. 2 lin.” 
“This minute species varies somewhat in size and also in colour; one example before me is of a deep
