1373. Hydroporus gi-acilis, Welincke, Beil. Ent. Zeit. XVI, p. 136. Spain. 



" Elongato-ovalis, postice attenuatus, feiTugineus, spai-sim p\mctulatus. Long. 2 m.m." 

 " Von langlicher form, rostroth, Kopf gross und ganz glatt. Halsscliild kurz uud breit, an den seiten 

 etwas gerundet, ausseret sparsam und fein punktirt, am vorder- iind hinten-ande leicht gebraunt. 

 Fliigeldecken lang gestreckt, nach hinten verschmalert, fein und sparsam punktirt, an der basis heller 

 gefarbt. Die ganze unterseite nebst beine gelbroth. " Dem H. pygmajus Sell, am nachsten stehend, 

 dui-cli die gleichbreite langliche form und durcli die feiue sparsame punktirung uutersclieiden." 

 Found at Malaga, by C. P. de la Brulerie. 



1374. HydropoiTis gravidus, Clk., Jouvn. Ent. I, ji. 413. Australia, (Port Essington). 

 " Ovatus, latus, subdepressus, crebre punctatus, ater. Long. corp. 1^ lin., lat. 4 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 depi'ession : 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 : antennae 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 tne hy its author, has unfortunately been lost in 

 transmission to tlie printers, and as iio copy of the work from which it is eictracted exists in Britain, so fa/r 

 as I have been able to learn, cannot now be replaced.^ 



1376. Hydroporus hansardii, Clk., Joum., Ent. I, p. 417. Australia (Moreton Bay). 



" Oblongo-ovatus, postice attenuatus, crebre punctatus, niger flavo-maculatus. Long. corp. 1^ lin., 

 lat. f-l Un." 



" 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 i-ufous ; 

 thorax broad, subparallel, in front the anterior angles rounded ; the surface is thickly p^mctate through- 

 out, in colour nifo-fiavous, the anterior and posterior margins being nan-owly 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 maculse ; legs and antennaa flavous." 



This is a Stemopriscus allied to S. clavatus (No. 361). — D. S. 



1377. Hydroporus hottentottus, Har., Mun. Cat. (Hydroporus coUaiis, Boh., Ins. Cafl". I, p. 255.) 

 CafTraria. 



" Hydroporus collaris ; oblongo-ovatus, convexiusculus, nitidus, niger; antennis basi pedibusque rufo- 

 testaceis ; prothorace i-ufo-testaceo, medio nigro ; elytris piceis, evidenter, minus crebre punctulatis, 

 disco antico stria tenui impressis. Long. 3, lat. 1| m.m." 



This diagnosis is supplemented by a longer description. I am quite doubtful as to the position to be 

 assigned to the species. — D. S. 



1378. Hydroporus humilis, King, Symb. phys. IV, t. 33, f. 11. SinaL 



" Nigro-piceus, antennis pedibusque testaceis, elytris piceis, basi obsolete testaceis. Long. lin. 2. 

 Habitat in Montes Sinai aquis."
