Genus BTJSONIA Distant 



The enlarged first apical cell of the tegmina is not at all 

 diagnostic for this genus, as used by Distant, since it occurs in 

 some other genera — in all degrees in Pedioscopus. Well shown 

 in the figure of the type, but not mentioned in the genus 

 characterization, however, is a unique character which well dis- 

 tinguishes this genus — the absence of upper lateral sutures of 

 front, the lower lateral margins being continuous with the 

 supra-antennal ridges. Idiocerus minor of Bierman ^ from Se- 

 marang, Java, belongs here, as may be seen at once from the 

 figure of the type. Two very inconspicuous species have been 

 encountered in the Philippines, which are, however, remarkably 

 distinct in their structural characters.

Synopsis of Philippine species of Busonia. 



a*. Clypeus very broad, convex-sided, and rounded at tip; ocelli nearer 

 to eyes than to median line; cross vein at base of first apical cell 

 and venation proximad of this, obsolete; no subapical cells; the 

 second apical cell broader at apex than at base, the third broader at 

 base than at apex, and the fourth far longer than third; clavus not 

 punctate scutellaris sp. nov. 



a^ Clypeus narrow, concave-sided, and emarginate at tip; ocelli as near 

 median line as to eyes; venation all distinct; one subapical cell; the 

 second apical cell as broad at apex as at base, the third broader 

 at apex than at base, and the fourth as long as third; clavus with 

 very large dotted punctures mindanaensis sp. nov.
