I cannot form any decided opinion as to the place of tliis name ; it may possibly prove a species of 

 Bidessus. — D. S. 



1336. Hydroporomorpha parallela, Bab., Tr. Eut. Soc. Til, 1841, p. 15. pi. 1, f. 3. Brazil. 



" Oblonga, antice obtusa, postice acuminata, lateribus parallelis, supra rufa, thorace antice et postice 

 elytrisque (apice marginibusque exceptis) fuscis ; corpora subtus, antennis pedibusque fusco-i-ufis.

" Head short, transverse, rounded in front, with two longitudinal slightly impressed fovese 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 ; disc smooth, ^\^th 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. Elytra of the same width as the thorax, oblong, the sides parallel for three-foiu-ths 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 ai'e rufous. Body beneath, legs and antennse, diill rufous. Hab., Rio de 

 Janeiro." 



This is a species of Celina allied closely to C. lougicornLs, No. G.52.— D. S. 



1337. Hydroporus aberrans, Clk., Tr. Ent. Soc. Lond. third ser. I, p. 426. Java. 



" Breviter ovatus, latus, parallelus, fortiter punctato-striatus, punctatus, testaceus, rufofusco notatus ; 

 capite le%'iter punctato, rufo-fusco ; thorace antice vix emarginato, lateribus rotundatis, basi pene 

 transverso, crebi'e punctate, testaceo, ad meilium fusco-adumbrato ; elytris sat latis, fortiter undique striis 

 punctatis octo latis omatis, punctatis, testaceis, lineis tribus rufo-fuscis a basi ad apicem subparallelis ; 

 coi-pore subtus fusco, antennis pedibusque rufo-flavis. Long. corj). liu. -t ; lat. lin. ^." 



" The only example that I have been able to examine of this species is an imperfect one received by 

 Mr. Bowling from Java : it presents very sufficient and strikiug characters ; tlie form of the insect is 

 short and parallel ; the sides of the thorax are much roimded, compi'essed at the anterior and posterior 

 angles ; the elytra are marked by eight deep strise, formed by closely an-anged broad punctures ; in 

 colour the surface is testaceous, the interstices between the first and second, the thii-d and fourth, the 

 fifth and sixth strise being irregularly rufo-testaceous." 



The type of this species has been destroyed, I am doubtful to what genus the insect should be 

 referred. — D. S. 



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 jiedibusque rufo- 

 flavis. T;ong. corp. ^ lin., lat. f lin." 



"This minute species varies somewhat in size and also in colour; one example before me is of a deep
