of the eyes (as seen from above) by the proportions of the posterior 

 tarsi, the strongly punctured pronotum, etc. 



6, H. hmdator, sp. nov. (Plate VI, fig. 4.) 



Elongate, parallel-sided. Shining black, pilosity pallid. Head, 

 apical half of 1st segment of antennte, an obscure ring on posterior 

 femora — dark fuscotestaceon s ; legs (including coxse, but excluding 

 the black 3rd segment of posterior tarsi), basal half of 1st antennal 

 segment, lateral margins of pronotum very narrowly, lateral margins 

 of elytra, exterolateral margin of clavus, flavotestaeous. Vertex a 

 trifle wider than the 2 eyes together. Apical half of 1st segment 

 of antennae a little swollen. Pronotum anteriorly with 2 submedian 

 impressions. Eyes touching pronotum, of which the base is rounded. 

 Orifices tuberculo-elevate exterolaterally. 



Long. 4'4 mill., lat. 1'4 mill. 



Hah. PULO Laut. 



7. Orcdoderm oUiqims, Uhler. (Plate VI, figs. 1, 2, 5, 23.) 



The apterous form of this species is doubtless an ant- 

 mimic, and is not unlike that of some of the European 

 genera. 



9 Black (greenish-bronzy reflections) ; antenna; (except apex of 2nd 

 segment), tibine, - etc., dark reddish-brown. Pronotum truncate 

 apically and basally, subrotundate laterally, base scarcely wider than 

 apex. Meso- and metanotum and 1st 2 (?) segments of abdomen not 

 wider (a little narrower) than pronotum. Abdomen widening 

 roundly from base of 3rd (?) abdominal segment, 3rd to 6th segments 

 forming a subelongate globe. Elytra short, reaching to the middle 

 of 2nd (?) segment. 



Hah. America, Massachusetts, Lowell. 



The male (macropterous form) is also figured. 



8. Berta lanlcanus (Kirby). 

 Java. Previously described from Ceylon. 



Hcspcrolabops, gen. nov. 



Closely allied to Lahops, Burmeister, but differing 

 radically in structure of head and pronotum. 



Elongate, parallel-sided, vertex and face medianly sulcate (an- 

 teriorly rounded), the prominent interolaterally emarginate eyes fixed 

 on long elevated peduncles which rise obliquely from the base.
