may be produced, the latter sometimes occurring on the inner branches 

 of the outer appendage also. Perithecium wholly free, concolorous 

 with the receptacle, narrow, but slightly inflated, the tip nearly as 

 broad as the bod}', and clearly distinguished by blackish suffusions; 

 the lip-cells large rounded and bent slightly inward. Spores 45X3.5 jjl. 

 Perithecium 90-100X24-28/1. Receptacle 80X 15-155X22 /z. Longer 

 appendages 135-150 fjL. Total length to tip of perithecium 175-280 /x. 

 On the tips of the elytra, wings and abdomen of Lactica varicornis 

 Jac. or a closely allied species. Palermo, No. 1462. 



Laboulbenia Blechri Spegazzini. 



Receptacle slender, hyaline, the basal cell not symmetrically 

 adjusted to the subbasal, which is slightly prominent above it on the 

 posterior side, while the basal bulges below the subbasal on the ante- 

 rior side; the subbasal somewhat longer than the basal, hardly 

 broader; cells III, IV and VI subequal and subisodiametric, cell V 

 very small. The insertion-cell, black, rather thin, not very broad; the 

 outer appendage erect, simple, its three lower cells rather deeply tinged 

 with olivaceous, especially externally, subequal, each somewhat 

 broader distally and thus rather abruptly distinguished from one 

 another; the rest of the appendage ciuite hyaline, tapering slightly: 

 basal cell of the inner appendage much smaller than that of the outer, 

 producing the usual branch on either side, each once or twice branched; 

 the whole forming a group of four to six branchlets olivaceous below, 

 which are relatively very stout, short, bent inward or across the 

 perithecium, the longest extending just above its tip, the lower cir- 

 cinate distally. Perithecium colorless, straight, its axis somewhat 

 divergent from that of the slender receptacle, the basal cell-region 

 forming an external rounded prominence, the junction of the basal 

 and subbasal wall-cells also prominent; the tip, rather stout, sub- 

 tended by a slight external prominence, the apex broad, the h^^aline 

 lips outwardly oblique, subtended by an olivaceous patch on the inner 

 side. Spores 35X3 ju. Perithecium 62-70X20-22 jjl. Receptacle 

 80-100 II. Appendages, longer, inner 55 ix, outer 110 ix. Total 

 length to tip of perithecium 140 /x. 



On Blechrus sp., at the tips of the elytra. Llavallol, No. 1979. 



A single specimen of the host was found bearing this species which 

 is most readily distinguished by its relatively very large incurved 

 inner appendages. The perithecium may become suffused with age, 

 but in the specimens examined it is quite hyaline, although they are 

 sufficiently mature to have produced spores.
