the coarser, oblique rugae at base of mctatliorax, and tbc 

 broad entire hair-bands oi' the narrower alxlomcn. It ii 

 structurally closer to //. leucozunius, from which it is at onee 

 known by the dark basitarsi. In the North Anuricau 

 fauna it may be compared with H. trizunatus, from Mhich it 

 ditt'ers by the much more closely punctured mesothorax and 

 the much stronger rugae of basal area of metathorax. 

 II. horishensis is not represented iu the Sauter coUectiou 

 from Formosa. 



The following table separates the females of four Formosan 

 species of Ualictus, and contrasts them with a number of 

 forms w Inch they more or less closely resemble : — 



Sides of protborax above mucb enlarged, 

 coucave, produced to au acute angle; 

 mesotborax witb very strong well-sepa- 

 rated punctures ; abdomen closely, very 

 minutely punctured. (Formosa.) peranc/vkdus, Ckll. 



Protborax normal, or only moderately pro- 

 duced at sides 1, 



1. Middle and bind tibias and tarsi clear fer- 



ruginous ; basal bands of second and third 

 abdominal segments extremely broad at 

 sides, but narrowed almost or quite to a 

 point in middle ; tegulte bright ferrugi- 

 nous; mesothorax sparsely punctured. 



(Samarkand.) equestris, Morawitz. 



Middle and hind tibiie and tarsi not thus 

 red (tarsi iu trizonatus sometimes partly 

 reddened) 2. 



2. Basal area of metathorax finely gi-anular 



(finely striate in manitouellus) ; meso- 

 thorax very finely punctured 3. 



Basal area of metathorax conspicuously 

 ridged, wrinkled, plicate or striiite (finely 

 striate in manitouellus) 5. 



3. Basal bands of abdomen pale fulvous, on 



second and third segments strongly nar- 

 rowed in middle ; wings dusky greyish. 



(Colorado.) manitouelhts, Ckll. 



Ba>al bands of abdomen cream-colour, not 

 narrowed in middle (except that on second 

 moderately so in trizonatus) 4. 



4. Wings very strongly reddened. (Mexico.) schenckii, Ritsema. 

 Wings little reddened. (Colorado.) trizonatus, Cresson. 



5. Hind margins of abdominal segments fei'- 



rugiuous or pallid. (Europe.) cakeatus (Scop.). 



Hind margins of abdominal segments 

 black Q. 



6. Bands at bases of second and third abdo- 



minal segments much narrowed in middle, 

 or interrupted, and always yellowish- 

 tinted or fulvous 7.
