342 THE ENTOMOLOGIST. 



scent in middle ; third with traces of a band at sides ; apex with two 

 widely separated short stout spines ; venter black, with black hair. 



2 . Looks exactly like the male ; face-marks nearly the same, 

 but scape all black, and lateral marks reduced to a stripe or band 

 along margin of clypeus ; third antennal joint slightly longer than 

 the next three together ; mandibles long and thick, strongly bent ; 

 middle tarsi wath hair black, except some red on basitarsus ; hind 

 basitarsus very broad, strongly concave and shining on outer side. 



Hab. Eight males and two females from Formosa (Sauter) ; 

 no special locality given. A very distinct species, which may 

 be compared with the following: A. florea, Sm., which differs 

 by the ferruginous femora, and the narrow white hair-bands on 

 abdomen; A. proserpina, Grib., which is more elongate, with 

 orange face-markings ; A. insularis, Sm., which differs at once 

 in the coloration of the abdomen ; A. brookicB, Bingh., which 

 has testaceous nervures, the clypeus with more yellow, and 

 lighter wings. The type of A. iirens is a male. 



Coilioxys afra sauteri, n. subsp. 



? . Length, 9 mm. ; hke C. afra, Lep., but mandibles black 

 (the apical tooth obscurely reddish) ; . legs and end of abdomen black ; 

 anterior border of mesothorax with a median trilobed patch of white 

 pubescence, instead of the stripe seen in C. afra, and there are no 

 patches on each side of it, as there are in afra ; axillar teeth with 

 the outer side straight (convex in afra). 



Hah. Taihanroku, Formosa, "11.6.08." (Sauter). This 

 should possibly be regarded as a distinct species, but it is 

 extremely close to C. afra. I suppose that Friese had this form 

 before him when he recently recorded C. afra from Formosa. 

 In its entirely black apex of abdomen it resembles the larger 

 C. emarginata, Foerst. 



Coelio.vys rhinosus, n. sp. 

 ? . Length, 11 mm. ; black, including the mandibles and legs ; 

 pubescence of the usual kind, white ; at sides of face dense and very 

 pale ochreous ; on anterior part of mesothorax loose, not forming 

 spots or patches ; eyes strongly pubescent ; front rugose, obtusely 

 elevated in the middle ; vertex with very large confluent punctures ; 

 cheeks densely covered with white hair ; antennae black ; clypeus 

 roughened but shining, strongly elevated in the middle to a keel, the 

 side view nose-like, with a convex outline ; lower margin of clypeus 

 strongly nodulose ; mandibles broad, with a long oblique cutting 

 edge ; mesothorax and scutellum very strongly and densely punc- 

 tured, the latter without any smooth edge ; scutellum very obtusely 

 angulate, not dentate, in middle ; axillar teeth short but evident ; 

 tubercles strongly keeled ; tegulae dark rufo-piceous ; wings brown, 

 hyaline basally ; abdomen strongly punctured, with narrow dull 

 white hair-bands, enlarged at sides ; transverse grooves on second 

 and third segments weak ; last dorsal very long, strongly keeled, 

 neither notched at sides nor turned up at end ; last ventral long and
