Suborder AMBLYCERA Kell. 

 Family UOTHEIDAE Nitzsch. 



Genus COLPOCEPHALUM Nitzsch. 

 Colpocephalum spinulosum obscurum subsp. nov. 



Of the same size as Colpocephalum spinulosum minor Kell., from 

 which it differs in the proportions of the head, the clear temples and 

 legs; the pitchy markings on legs; the absence of clear pustules along 

 the posterior margin of the abdominal segments ; and in the darker 

 lateral abdominal bands, which are abruptly darker than the trans- 

 verse bands. 



Piaget's description of C. spinulosum (Les Pediculines, p. 

 563, pi. XLVII, 3) is very clear and the plate excellent, and 

 both he and Mr. Kellogg agree on the statement that the male of 

 both C. spinulosum and C. spinulosum minor Kell. has a single 

 transverse row of large pustulated hairs on each abdominal 

 segment, while in the female there are two such rows. The 

 present form has (in both male and female) a row of fine hairs 

 along the posterior border of the metathorax and each abdom- 

 inal segment (except the ninth), but set closely together and 

 in very small pustules of exactly the same size as the numerous 

 small ones scattered over the whole segment. In the present 

 form the median transverse and longitudinal clear bands are 

 wanting, while the coxal bands are entire, very conspicuous 

 and pitchy brown, also the sternal markings of both prothorax 

 and metathorax. The temples, sides of front part of head and 

 the front of the clypeus are perfectly clear, while the median 

 portion of the head is clear brown, with the pitchy ocular, 

 frontal, and occipital markings of true spinulosum. With 

 these exceptions the new form agrees better with Piaget's de- 

 scription and plate than with Mr. Kellogg's plate of C. s. minor 

 (New Mall. Ill, 112, pi. VII, Fig. 9). 



One male and a female from the Turnstone (Arenaria inter- 

 pres], C. spinulosum minor Kell., was taken from the Sander- 

 ling (Calidris arenaria), while true C. spinulosum Piaget was 

 described from Limosa melanura.
