On Mormolyce phyllodes Hagenb. Perak, Molucca, Java. 



The writer is indebted to Professor Riley for abundant material of 

 this species found by Mr. Schwarz on a specimen of Mormolyce in the 

 National Museum labelled " Java," as well as to Mr. Beutenmueller 

 who has kindly sent material derived from a specimen in the Central 

 Park Museum labelled Molucca. Professor Giard has also most gen- 

 erously allowed him to examine the original specimen of Mormolyce 

 from Perak on which the types of L. Kunkelii were associated with 

 the present species. The two species are very closely allied, and 

 were found intermingled towards the base of the elytra, although the 

 smaller was much more abundant on the flattened margins where it 

 presents the appearance under a hand lens of a grove of little palm- 

 trees. The absence of any transitional forms between the two species 

 seems to render it unlikely that they should prove merely varieties of 

 a single form, while the much smaller size of L. palmella, its wholly 

 opaque and short receptacle, straight short-necked perithecium, large 

 hoof-like base, together with the absence of furcation in the main axis 

 of the two lateral branches of its inner appendage, afford constant and 

 sufficient specific differences. The antheridia appear to be repre- 

 sented by flask-shaped bodies borne on short hyaline branches near 

 the tips of the branchlets of the inner appendages. The trichogynes 

 are well developed and more or less copiously branched. 



Laboulbenia melanotheca, nov. sp. 



Tinged with pale reddish brown, except the nearly black perithe- 

 cium. Perithecium long, straight, symmetrical, subcylindrical or but 

 slightly inflated, narrowed abruptly to the symmetrical apex, its basal 

 wall cells elongated to form a neck-like stalk about one fourth as long 

 as its main body, projecting from the receptacle at an angle to its long 

 axis towards and beyond the appendages. Appendages as in L. mex- 

 icana, hardly exceeding the perithecium in length, consisting of two 

 basal cells ; the outer producing an outer and an inner branch either 

 simple or once branched ; the inner producing single branches on 

 either side. Receptacle elongate expanding very gradually from the 

 base, distally abruptly rounded and contracted below the insertion cell
