distinct in proportion to its size. //. ClarJcii is a little more parallel 

 and broader towards the shoulders, and the four anterior feet of the 

 male arc somewhat more dilated than in the species before us. 

 Head with two antical depressions, the surface is obsoletely granu- 

 lated and finely punctate-rufous : the thorax is rounded in front, 

 the sides being subparallel ; the surface is finely and sparingly punc- 

 tate, fiavo-rufous, the base and two medial basal subcircular mark- 

 ings being fuscous : elytra with two faint striae, one sutural and the 

 other submedial ; in colour pale testaceous or navo-testaceous, with 

 four or five irregular, interrupted, longitudinal lines of fuscous, 

 which vary much, in different examples, in breadth, in length, and 

 in degree of continuation ; for the most part, these lines are so trans- 

 versely interrupted that they form (in general appearance) three 

 irregular transverse bands ; the spines at the apex of the elytra arc 

 certainly decidedly more developed than in H. ClarJcii (in which 

 species they are almost obsolete), assimilating in development to 

 those of H. assimilis, Payk. 



My friend Mr. Gray and I captured this handsome species at 

 Malaga, on May 13 and 29, 1856, in pools formed by mountain 

 watercourses, in company with Colymbetes coriaceus, Agabus brun- 

 neus, and others. I have also received the species from M. Schau- 

 fuss as undescribed, from the South of Spain. 



H. halensis, Fab. 



H. ovalis, subtiliter pubescens, pallide fuscus : capite flavo, ad latera et 

 apicem fusco : thorace pubescenti-tiavo, undique juxta medium irregu- 

 lariter fusco notato : elytris pubescentibus, pallide testaceis, liueis sex 

 ad basin ab apicem fuscis, attenuatis, sequalibus, hie illuc interstitiis 

 fuscis: pedibus rufo-flavis, tarsis anterioribus fuscis, tarsis posticis 

 rufo-flavis ad articulos fusco annulatis : antennis flavo-rufis, articulis 

 apicalibus fuscatis.

Oval; perceptibly broader and Jess parallel in the sides than H. 

 assimilis, Payk., the sides of the thorax also being continued in a more 

 direct line with those of the elytra than in this species ; the coloration 

 is entirely different, being less tinged with rufous, and the longitudinal 

 lines on the elytra being narrower : the head is narrower ; the two de- 

 pressions at the inner margins of the eyes are more distinct ; in colour 

 the lateral margins are much more broadly fuscous : the thorax is 

 broader than in H. assimilis, Payk. ; at the anterior margin is a single 

 regular row of distinct fuscous punctures (not frequent and unarranged 

 minute punctures); the surface is pubescent, thickly and evenly punctate 

 throughout. In H. assimilis the surface is rather minutely granulated, 

 the granulations being interspersed with more distinct punctures ; the
