1893. Ctenus {viW Phoiieutria'^) Po//zV, van Hass, ^,22 mm. 



Type in coll. J. R. van de Poll, Bysenburg, Utrecht. 



Tijdsclir. voor Ent. xxxvi. p. 146. Hah. Sumatra 



{J. L. Kannezi'eter). 

 ^ . Tot. len. 22, carap. 12, abd. 10 mm. Pedes 4, 1, 2, 3. 

 Ocular quadrangle nearly square. Posterior centrals a little 

 lare^cr than anterior centrals ; 2nd row a little procurved. 

 " Clypeo minimo " — '' ventre in medio nigrOj cum duabus 

 seriebus longitudinalibus punctorum ])arvorum luteorum." — 

 "Tarsi longe biunguiculati,"^ — "Pars tibialis extus cum forti 

 processu transverso, parnmper sursum curvato, obtuso, sed ut 

 videtur apice bifido ; bulb! laminji oblongato-ovafa, tarn supra, 

 ad basin, processui tibiali vicinam, quam subtus ipso bulbo, 

 in medio, dente conico provisa, hoc illo multo validiore." 



No mention is made of the spinulation, but doubtless it is 

 the same as that of other species closely allied, which possess 

 the characteristic rows of white spots beneath the abdomen. 

 Without seeing the type, one is of course unable to say any- 

 thing worthy of confidence, but I have not yet met with any 

 forms from tlie east in which the ocular quadrangle is square 

 and the anterior eyes only a little smaller than the posterior ; 

 though these forms occur in the Neotropics and others 

 characterized also by rows of white spots beneath the abdomen. 

 l)r. van Hasselt has most kindly informed me of the 

 whereabouts of the type of this species.

1893. Ctenua argentipes^ van Hass. (J, 16 mm. Tijdschr. 

 voor Ent. xxxvi. p. 148. Type in coll. J. R. van de 

 Poll, Bysenburg, Utrecht. Hah. Sumatra {J. L. Kan- 

 nezieter). 

 ^ . Tot. len. 16, carap. 8, abd. 8 mm. Pedes 4, 1, 2, 3. 

 In general appearance resembling Pollii \ ocular quad- 

 rangle, however, broader than long; venter similarly decorated 

 with rows of white spots, but four instead of two. Fem. iii. 

 and iv. " late semiannulati vel maculati." — " Tibiis, pra^sertim 

 supra, pulchre et dense sed non longe argenteo-albo pilosis (iii. 

 excepto). Processus tibialis similaris^ sed magis dentiformis, 

 et ut videtur, non bifidus.'''' — " Processus ad bulbi laminam 

 basalis multo longior et magis incurvatus, quasi calcaratus, 

 calcare hoc postrorsum versus dentem tibialem inclinato." 



This species is evidently very similar in general appearance 

 to G. Floicerij sp. n,, though I am entirely unable to reconcile 

 the above description of the palpal organs with those of 

 Floueri {cf. PI, IV. fig. 25), and I have not the smallest 

 doubt about the distinctness of the two species, short of actual
