458 ABNORMAL COLEOPTERA. 



very narrow ; the wings are broader than their length measured from the 

 pseudelytra to apex of abdomen, and have scarcely any visible nervures ; 

 the posterior trochanters are short and the tarsi are two-jointed ; two 

 species are known, one from Mauritius and one which has occurred in 

 Britain. 



E. tenuicornis, Kirby ( Wdlkeri, Curt.). Dull ochreous-fuscous ; 

 eyes black and shining scarcely pedunculate ; wings iridescent, pale 

 fuscous, with the anterior margin considerably thickened and darker 

 fuscous ; the few nervures are also fuscous ; abdomen more or less spotted 

 above and beneath ; legs and antennae pubescent ; thorax shorter and 

 more gibbose than in SStylops, as well as the postscutellum; tarsi two- 

 jointed (at all events apparently) much more slender in the first pair than 

 in the others. L. 1 mm. 



By sweeping herbage; parasitic on Bomlus and perhaps on Andrena and Ha'ictus ; 

 extremely rare ; Soutbgate, near London (Walker) ; Glauvilles Wootton (very rare ; 

 a couple only taken by Mr. Dale, on Whitedown, June lltb, 1830, and in Aldermead, 

 June 27th, 1839) ; Ireland, Belfast (Templeton) ; the latter specimen is now in the 

 University Museum, Oxford. 



HALICTOPHAGUS, Dale. 



In this very curious genus the antennae are short and seven-jointed and 

 flabellate, the tarsal and second joint being stout, and each of the 

 remainder being produced into a lobe on the outer side, the lobes 

 gradually decreasing in length to the apical joint, which is inserted at 

 the base of the lobe of the penultimate joint ; the lobes are subniem- 

 branous and are ornamented with semitransparent punctures ; the eyes 

 are prominent and strongly granulate; the pseudelytra are strongly 

 clavate and very slender at base ; the abdomen is rather short and is in 

 great measure concealed by the postscutellum, which has a long deep 

 furrow at base ; the wings are broad with rather strong nervures ; the 

 anterior coxae are long, the femora rather short, the tibias short and 

 compressed, and the tarsi three-jointed ; one species only appears to be 

 known. 



H. Curtisii, Dale. Black and slightly glossy, clothed with a brown 

 velvety pubescence ; antenna and legs dull brownish ochre ; wings 

 slightly tinged with brownish ochre and obscurely iridescent ; nervures 

 brown, broad and strongly marked ; wings less rounded than in Elenchus, 

 broader in front and narrowed behind ; tips of the joints of the tarsi 

 and apex of abdomen ochreous. L. 1 mm. 



Parasitic on species of Halictus ; very rare ; taken by Mr. Dale in August ill 

 company with the male of Halictus eeratus (?) by brushing some long coarse grass 

 and thistles close to the sea, on a rock called Durclle Door at Lulworth Cove ; Mr. 

 Dale also recorded the fact of his having found a larva in Halictus ? 4 guttatus taken 

 in the New Forest in April ; a number of Halicti infested with apterous Strepsip- 

 terous females were once found by Sir S. S. Sannders near Folkestone ; these very 

 likely belonged to the present species, but no mule was discovered.
