HEXiODES, Latrcille. 



Fourteen species belonging to this genus are found in Europe, of 

 which two occur in Britain ; they may be easily known by the very 

 small transverse third joint of the antennae, which are long and slender ; 

 the eyes are very large, the thorax almost semicircular, and the inter- 

 mediate coxa- contiguous. 



The larva of Cyphon pallidus (Helodes minuta) is described and figured by 

 Chiipnis et Candeze (Cat. des Larves des Coleopteres, p. 153, pi. v. fig. 5) ; it is 

 5-6 mm. in length, of a greyish-black colour, rather short and broad, somewhat 

 onisciform ; the head is much narrower than the prothorax, which is about as long 

 as the raeso- and metathorax together ; the anal segment is considerably narrower 

 than the preceding ; the antennae are very long, being almost as long as a third of 

 the body, and the legs are short and, unless stretched out, not visible from above ; 

 the sides of the body are thickly fringed with fine short cilia; these larvae live on 

 aquatic plants, and in the early part of June change into pup;c, from which the 

 perfect insect emerges in about fifteen days. 



I. Head and thorax reddish -testaceous H. MINUTA, L. 



II. Head and thorax black, the latter with margins more 

 or less broadly testaceous H. HARQINATA, F. 



H. minuta, L. (pallida, F.). Oblong-ovate, moderately convex, 

 clothed with pale pubescence, testaceous, with the eyes, suture, and 

 apex of elytra, and the abdomen, black; the colour is somewhat 

 variable, the elytra being sometimes unicolorous with the apex narrowly 

 black, and sometimes dark with the shoulders only lighter; head small, 

 eyes large ; antennae long, stouter in male than in female, dark with the 

 base light ; thorax finely punctured, almost semicircular ; scutellum 

 large, distinctly punctured ; elytra broader than thorax, elongate oval, 

 thickly and plainly punctured, with distinct traces of raised lines ; legs 

 reddish-testaceous, posterior femora plainly punctured. L. 3|-4 mm. 



Male with the antennae stouter than in female, and furnished with 

 erect pale pubescence ; last ventral segment of abdomen emarginate at 

 apex, and with a deep semicircular impression, the sides of which are 

 fringed with greyish hairs.
