4 THAXTER. 



which cell g bears distally the terminal free appendiculate cell i, from 

 which the primary appendage arises terminally. On hosts belonging 

 to genera other than Laccophilus several species occur in which no 

 septum separates cell /from cell h, so that the pointed end of the former 

 itself bears the appendage, which arises next the perithecium; while the 

 latter is not distinguished as a distinct cell. 



In addition to the new forms on Laccophili from the West Indies 

 enumerated below the following were also met with. 



Chitonomyces hyalinus Th. A form hardly separable from this 

 species was found at Sangre Grande, Trinidad. Its general habit is 

 distinctly more slender than that of the type, especially the basal 

 portion of the receptacle and cell i. The elevation which subtends 

 the apex of the perithecium, and projects somewhat inward on the 

 right side, is also distinctly more prominent. Otherwise it shows no 

 essential differences. A form smaller and somewhat stouter than the 

 type was also found at the Grand Etang, Grenada. Both these forms 

 occur on the posterior legs. 



C. 2)sittacopsis Th., resembling the type in all respects was found 

 commonly both in Trinidad and at the Grand Etang on a single spe- 

 cies of Laccophilus, Nos. 2687 and 2684. 



C. appendiculatus Th., agreeing essentially with the type, was found 

 at Sangre Grande, near the base of the left elytron of a single individual 

 of Laccophilus, No. 2680. 



C. simplex Th., exactly resembling the type and growing in the 

 same position, was found rarely at Sangre Grande, No. 2684. 



C. paradoxus Peyr., showing a considerable degree of variation both 

 in color and in the conformation of the tip of the perithecium, was 

 found commonly on three species of Laccophilus in Grenada and 

 Trinidad. 



C. rhyncostorna Th., was found on a peculiar Laccophilus in the 

 Arepo Savanna, at Cumuto, Trinidad, and showed no essential differ- 

 ences from the type. 



C. distortus Th., growing in the usual position on the front legs, was 

 found rarely at the Grand Etang and varies slightly from the type. 



C. uncinatus Th., somewhat larger and more slender, was found 

 rarely at the Grand Etang and also at Sangre Grande. In the Trini- 

 dad material the basal cell of this species tends to become conspicu- 

 ously blackened, and the projection of cell g is appressed against the 

 adjacent tip of the perithecium. The longest individual measures 

 175 M- 



C. marginatus Th. A form agreeing in all respects with the type was 

 found on two individuals of Laccophilus at the Grand Etang.
