THAXTER. — LABOULBENIALES PARASITIC ON CHRYSOMELIDAE. 31 



the tip deep black, short, broad, abruptly distinguished; the lip- 

 edges broadly hyaline, contrasting; the apex more or less rounded, 

 two indistinct papillae above the external pore. Perithecia .60-65 X 

 25 ijl. Spores as long as venter, about 40 X 4 ju. Receptacle 80 X 

 35 /x. Appendages, longest 175 ix. Total length to tip of perithecium

On tip of the elytron of Nodostoma sp., Mindanao, Philippines, 

 No. 2386, received through the kindness of Mr. Oakes Ames. 



An insignificant species very similar to some of the forms on Carabi- 

 dae allied to L. flagellata. 



Laboulbenia Philippina nov. sp. 



Receptacle varying in length from the variable elongation of cell 

 II; hyaline, becoming tinged with straw-yellow; cells I and II 

 relatively large, of about the same diameter, cell II often far longer; 

 cells III, IV and VI subequal and subisodiametric; cell V very small, 

 triangular. Basal cells of the perithecium hyaline, well defined, 

 contrasting with the venter; that lying externally above cell VI 

 usually prominent; venter rich contrasting translucent purplish 

 brown; slightly, often symmetrically, inflated; the tip more or less 

 well defined, rather abruptly so externally where a narrow margin is 

 deeply suffused; otherwise quite hyaline, except for a black patch 

 which subtends the rather prominently rounded inner lip-cell; the 

 lip-edges hyaline, outwardly oblique. Appendages wholly hyaline, 

 becoming yellowish; the basal cell of the outer appendage giving 

 rise to an outer and an inner branch; the basal cell of the inner ap- 

 pendage much smaller, producing a usually simple branch on either 

 side; all the branches rather stout, elongate, somewhat divergent or 

 even slightly recurved, slightly tapering. Insertion-cell contrasting 

 with all the cells about it. Perithecium about five sixths free, 85-100 

 X 28-35 fx. Spores 50 X 3.5 /x. Receptacle 100-225 X 38^2 y.. 

 Appendages longest 210-420 fx. Total length to tip of perithecium 

 150-335 li. 



On the elytra and legs of a chrysomelid near Rhembastus: No. 2451 

 Manila, Philippines (Banks). 



Very like some forms of L. polyphaga, and distinguished from 

 related forms on Chrysomelidae by its often elongate form, hyaline 

 or evenly pale yellow color, its stout elongate concolorous appendages 

 and deeply suffused contrasting perithecium.
