128 staphylinidj:. [Homaloia. 



Male with the hind margin of ventral plate of seventh segment gently 

 rounded, female with the same part excised and ciliate. 



In (lung^ ; local, but somewhat widely distributed ; Ilainpstead ; Tonbridore ; New 

 Forest; Sniiillheath and Knowle, n^ar Birmingham; Manchester; Nortliumberhmd 

 district, very rare, Wallington (Power), and Whitley Sands; Scotland, scarce,

Dr. Sharp in his description compares this species with IT. parva and 

 H. aframentaria ; from the former its more thickened antennae, broader 

 head, less transverse thorax (which is also less narrowed in front), ratlier 

 more sparing punctuation, and the shorter lower setse of its tibise, dis- 

 tinguish it ; it is much smaller than H, atramentaria, with the anterior 

 parts blacker and more shining, and the antennte shorter and more 

 thickened towards apex. In the last European catalogue it is given as a 

 variety of H. Icevaiw, Muls. et Rey, with which species Dr. Sharp does 

 not even compare it ; it is smaller than that species and much blacker 

 (the elytra in H, Icevana being brown, and the apex of hind body 

 testaceous or pitchy); the antennae, too, appear quite different, the 

 penultimate joints being scarcely transverse in H. Icevana, and plainly 

 tr.msverse in //. setigera ; they are also, taken as a whole, shorter ; the 

 male characters, moreover, are quite different, the dorsal plate of seventli 

 segment of hind body being emargiuate and toothed in H. Icevana, and 

 without any peculiar structure in H. setigera. 



K. laevana (sub-gen. Bimetruta, Muls. et Rey). Black, rather 

 shining, with the elytra brownish, and the apex of hind body more or 

 less obscurely pitchy or testaceous ; from H. setigera it differs as above ; 

 it resembles both H. cinnamoidera and H. atramentaria ; from the 

 former it is distinguished by having the antennae stouter towards apex, 

 the head, thorax, and elytra more shining and less densely punctured, 

 and the hind body less narrowed towards the apex and more sparingly 

 punctured ; from the latter it is easily separated by the stouter antennae, 

 unicolorous brown elytra, pale legs, and narrower thorax ; the head is 

 rather broad ; the antennae are moderately long and stout Avith the 

 penultimate joints only slightly transverse, and the eleventh joint long, 

 longer than the two preceding together ; thorax a third broader than 

 long, rather closely and finely punctured with a few outstanding set^e, 

 sooietimes with a short channel in front of scutellum, sometimes smooth; 

 elytra one-third longer than thorax, rather closely and finely and some- 

 what rugosely punctured ; hind body with segments 2-4 distinctly and 

 not very closely punctured, fifth more sparingly punctured, sixth almost 

 irapunctate ; legs yellow, intermediate and posterior tibiae with two fine 

 setae, the one nearest the knee the shortest. L. 2i-2| mm. 



Male with the hind margin of dorsal plate of seventh segment emar- 

 ginate in middle with two teeth, placed close together, on each side.
