1373. Hydroporus gracilis, Wehncke, Berl. Ent. Zeit. XVI, p. 136. Spain. 
“ Elongato-ovalis, postice attenuatus, ferrugineus, sparsim punctulatus. Long. 2 m.m.” 
“Von linglicher form, rostroth, Kopf gross und ganz glatt. Halsschild kurz und breit, an den seiten 
etwas gerundet, ausserst sparsam und fein punktirt, am vorder- und hinterrande leicht gebraunt. 
Fliigeldecken lang gestreckt, nach hinten verschmiilert, fein und sparsam punktirt, an der basis heller 
gefirbt. Die ganze unterseite nebst beine gelbroth. ‘Dem H. pygmeus Sch. am nichsten stehend, 
durch die gleichbreite lingliche form und durch die feine sparsame punktirung unterscheiden.” 
Found at Malaga, by C. P. de la Brilerie. 
1374. Hydroporus gravidus, Clk., Journ. Ent. I, p. 413. Australia, (Port Essington). 
“ Ovatus, latus, subdepressus, crebre punctatus, ater. Long. corp. 14 lin, lat. $ lin.” 
“ Broad, depressed, the surface is very thickly and coarsely punctured throughout, in colour black ; 
head broad, punctate; the surface is unmarked by any fovea or depression: thorax broad, the anterior 
angles rounded, the sides broadly marginate ; in colour black, the marginations being obscurely tinged 
with rufous, more distinctly near the basal angles; elytra unmarked by any depression ; longitudinal 
line or stria pitchy black ; near the apex and also medially (at the extreme edge of the marginations) is 
an obscure rufous marking : antennz fuscous, the basal joints being rufo-fuscous : legs fuscous.” 
This is a very distinct species of Antiporus, somewhat near H. blakei, Clk., (No. 434).—D. S. 
1375. Hydroporus habelmanni, Wehncke, Ent. M. B. I, p. 76. Europe. 
[This description, copy of which was kindly sent to me by its author, has unfortunately been lost m 
transmission to the printers, and as no copy of the work from which it is extracted exists in Britain, so far 
as I have been able to learn, cannot now be replaced. | 
1376. Hydroporus hansardii, Clk., Journ., Ent. I, p. 417. Australia (Moreton Bay). 
“ Oblongo-ovatus, postice attenuatus, crebre punctatus, niger flavo-maculatus. Long. corp. 14 lin., 
lat. $-? lin.” 
“ Oblong-ovate, parallel, somewhat attenuated at the apex, thickly and deeply punctate, black. Head 
with two small punctuations between the eyes, black, with a medial longitudinal line of dark rufous ; 
thorax broad, subparallel, in front the anterior angles rounded ; the surface is thickly punctate through- 
out, in colour rufo-flavous, the anterior and posterior margins being narrowly fuscous black ; the 
posterior marking consists sometimes of two submedial spots ; elytra subdepressed, thickly punctate, of a 
dull black colour, with the lateral margins and also six small longitudinal markings (three on either side 
of the suture) flavous ; the lateral margins, narrowly flavous continuously, are more broadly marked by 
three longitudinal flavous maculz ; legs and antenne flavous.” 
This is a Sternopriscus allied to S. clavatus (No. 361).—D. 8. 
1377. Hydroporus hottentottus, Har., Mun. Cat. (Hydroporus collaris, Boh., Ins, Caf I, p. 255.) 
Caffraria. 
“‘ Hydroporus collaris ; oblongo-ovatus, convexiusculus, nitidus, niger; antennis basi pedibusque rufo- 
testaceis ; prothorace rufo-testaceo, medio nigro; elytris piceis, evidenter, minus crebre punctulatis, 
disco antico stria tenui impressis. Long. 3, lat. 14 m.m.” 
This diagnosis is supplemented by a longer description. T am quite doubtful as to the position to be 
assigned to the species.—D. 8. 
1378. Hydroporus humilis, Klug, Symb. phys. IV, t. 33,2) LE Sinar 
“ Nigro-piceus, antennis pedibusque testaceis, elytris piceis,; basi obsolete testaceis. Long, lin. 2. 
Habitat in Montes Sinai aquis.”
