(Calcutta, India). This is a clear case of straggling, the bird 

 skin from which the parasite was taken having probably been tem- 

 porarily near the skin or body of some gull or tern. 



Nirmus clypeatus, n. sp. 

 (Plate xiv, figs. 3, 3a and 3b.) 



A single male specimen from Co;'t'«<s co/'w^' a; (Kashgar, E. Turkes- 

 tan). This species is Lipeuroid in general aspect of head and Nirmoid 

 as to hind body. 



Description of male : Head truncate conical, with transpar- 

 ent, expanded clypeus, the latter being the only part of the body 

 without some colour. Portion of head in front of antennae con- 

 siderably longer than that behind. A hair on the dorsal surface in 

 the rounded anterior lateral angle of the clear portion of the cly- 

 peus ; a marginal hair at the beginning of this clear portion and 

 two more submarginal ones, one dorsal and one ventral, just 

 behind ; another hair on the margin at the distinct suture and a 

 long one on the ventral surface directly mesad ; also a hair on the 

 margin some distance above the antennae and a ventral submar- 

 ginal one midway between it and the suture. Clypeal signature 

 broad, sides nearly parallel, obtusely pointed behind and somewhat 

 paler than the general colour of the head. A light space before the 

 mandibles, enclosed laterall}^ by incurving internal bands. An- 

 tennal bands darkest where they turn inward before the antennae, 

 extending forward a little past the origin of the clear portion of 

 the clypeus and interrupted at the suture. Trabeculae acute, 

 slightly shorter than the basal segment of the antennae. Antennae 

 long, filiform, with first joint short, about the same length as the 

 fourth ; second segment longest, about as long as the two following 

 together, and the last second in length. Eyes inconspicuous with 

 a long hair. Temples flattened, slightly convex with rounded 

 posterior angles ; two hairs and a short prickle before these angles 

 and narrow, black marginal bands extending from the posterior 

 hair forward to the eye. Occiput slightly concave with anterior 

 margin of prothorax showing through. Occipital bands pale, not 

 reaching the occiput ; space between bands a little lighter in colour 

 than the temples with occipital signature visible. 



Thorax about one-third shorter than head. Prothorax quadri- 

 lateral with sides slightl}^ convex. Marginal bands present, turn- 

 ing in before they reach the posterior margin, not meeting on the 

 meson ; coxal bands distinct; a short hair in the posterior lateral 

 angles. Metathorax with diverging sides and posterior margin 

 obtusely angled on the abdomen. Three hairs arising from a clear 

 pustule in the posterior lateral angle and two more near them 

 with another small one, as shown in fig. 3b. Legs stout with few 

 hairs. 



Abdomen, excluding the first segment, elliptical, elongate, 

 widest at the fourth segment; first segment appearing as a con- 

 striction, with sides slightly converging, narrower than metathorax
