The snakefly, Inocellia pilicornis Carpenter, was described in 1959 
(Psyche, 65: 56-58) from three males collected in the states of Nuevo 
Leon and Tamaulipas, Mexico. These males were unique among 
known Raphidiodea in possessing moniliform antennae, their seg- 
ments bearing long radiating setae, arranged in a definite pattern. In 
July, i960, Dr. H. F. Howden, who collected one of the males of 
the original set, found the first known female of this species, along 
with another male, very near the type locality. It now turns out that 
the female also has moniliform antennae, but the hair covering of the 
antennae, although distinctly different from that of other species, is 
not as similar to that of the male of pilicornis as might be expected. 
The color markings of the female are like those of the male type, 
except that the median white marks on the meso- and metanotum and 
the abdominal tergites are in the form of patches instead of a contin- 
uous stripe. The forewing is 6.8 mm. long and 1.8 mm. wide; the

pterostigma, having a maximum length of 1 mm. and a width of a 
little less than .5 mm., is relatively shorter than in the male. The 
wing venation is like that of the holotype, illustrated in my account
