slightly irregular outline (fig. 8) ; but it may also attack the thorax 

 and head, and very often occurs on the legs, where it assumes a 

 long fusiform outline, like that of a hysterium (fig. 7). Individuals 

 of the latter type which have developed on the tibia, from a point 

 of infection near the terminal claws, are sometimes connected with 

 the original point of infection by a narrow primary thallus which 

 remains unchanged on the intervening joints of the leg, spreading 

 out and producing the secondary stage only on the broader and 

 more nutritious tibia. 



The relationships of this fungus are quite obscure. The 

 general characters of its primary stage might suggest a resemblance 

 to some Asterinae, or to a similar incrusting type. Its mature 

 condition, however, evidently a Fungus Imperfectus, seems to give 

 it a formal place among the Leptostromaceae. Its method of 

 sporulation, which in certain respects recalls that of the Chalareae, 

 or of Sporochisma or Endoconidium among the Hyphomycetes, 

 would seem to make its position in this group an isolated one. 



Termitaria Snyderi, nov. sp. (figs. 13-17). — Characters of the 

 genus. Sporogenous filaments with blunt or flat perforate termina- 

 tions forming an even hymenium. Total thickness of sporo- 

 dochium 70-80 /x; basal region including primary thallus 18-20 ju; 

 sporogenous region 55-65 /x, the upper zone 25-28 ju; sporogenous 

 hyphae a little over 3/1 in diameter; free spores about 3.5X2/X. 

 Sporodochium on abdomen 400 X 400- 1 000 /x . 



On workers and soldiers of Reticulitermes flavipes and R. virginicus, Wash- 

 ington, D.C., the former also vicinity of Boston. On Reticulitermes, nov. sp., 

 California. On R. lucifugus, Sardinia. A specimen on Rhinotermes marginalis 

 from Turkeit, British Guiana, kindly communicated by Nathan Banks, does 

 not appear to differ from the type. The material, however, is too scanty for 

 a satisfactory determination. 



This form, which is evidently widely distributed, was first observed by 

 Snyder, to whom I take pleasure in dedicating it, and who has figured its 

 gross appearance in jig. 9c, p. 29, Bull. 94, Part II, Bureau of Entomology. 

 It was first sent me at his request by A. D. Hopkins with an inquiry as to 

 its possible fungus nature, and has also been brought to my laboratory by both 

 Snyder and Smulgan from the Boston region. 



Termitaria coronata, nov. sp. (figs. 6-12). — Sporogenous hyphae 

 bearing distally a crown of several, more often four, brown-tipped,
