('<(ll)<)C(>iilialiiiii vcratruni n. sp. 



(l'l. 7, tty. '.).) 



A male, a female and two young from Ardea {Htrodias) alba. In maikings 

 and general appearance this species approaches C. Irochioxum Nitzsch from Ardea 

 (Botaurus) stellaris, but the dimensions and shape of head are markedly different. 



Male, length I.06 mm., widtli O.es mm., abdomen nearly wholly colored by the 

 broad transversal bands darkest at ends as in trochioxum but head much longer in 

 Proportion to width than in this species; the body one-fourth smaller than trochioxuiii. 

 Head, length O.34 mm., width 0.58 mm.; wider than broad but with füll rounded clypeal 

 portion flatly rounded anteriorly; temples rather thin and narrowly rounded; hairs with 

 rather weak pustulations in temporal angles and along occipital margin ; distinct 

 brown ocular blotches and narrow blackish occipital border fading out on temples; 

 in front of strong antennal blotches a paler brown rather indistinct band extending 

 anteriorly to a pair of small clypeal blotches. Prothorax with jirominent lateral 

 angles each bearing a short spine and a longish hair ; two longish hairs in postero- 

 lateral angles; whole segment translucent brown. Metathorax with rapidly diverging 

 sides, all brown with clearer sutural space at junction of meso- and metasegments; 

 longish non-pustulated hairs in postero-lateral angles and on posterior margin. x4b do- 

 rnen ovate, with longish non-postulated hairs along posterior margins of segments, 

 and Single long hairs in postero-lateral angles; all segments crossed by broad brown 

 transverse bands leaving only narrow sutural lines uncolored; lateral ends of the 

 transverse bands darker ; posterior margin of last segment rounded. 



Female, length 2 mm., width 0.8 mm.; head length O.37 mm., width O.03 mm.

Colpocephsiliim xeiiicuni n. sp. 



Males and females from Ardea {Ardetta) sturmi. A curious form of Colpocephalnm 

 quite distinct from any described species. Characterized by the long, slender, sub- 

 parallel side crenulate body, almost unpatterned, and the elongate head with odd- 

 shaped swoUen backward projecting temporal lobes. 



Male, length l.i» mm., width O.0 min.; slender, abdomen hardly wider than 

 head, body with sub-pai"allel sides and all pale. Head, length 0.4 mm., width 0.4" 

 mm.; head thus nearly as long as wide across temples; palpi and especially antennse 

 projecting conspicuously ; ocular margin deep and long, the swoUen heavy temporal 

 regions with long sloping anterior face, and projecting well behind occipital margin; 

 the temples with several long, non-pustulated hairs, and many very small spines on 

 antero-lateral angles; small blackish ocular blotches and pale brown antennal bands, 

 but otherwise uncolored. Prothorax small, much narrower than head; lateral angles 

 small but conspicuous with long hair and spine; also several hairs along posterior margin; 

 pale color. Metathorax with numerous longish hairs in postero-lateral angles and along po- 

 sterior margin; color pale translucent brown like head and prothorax. Abdomen slender, 

 sides sub-parallel tapering gradually posteriorly; lateral margins somewhat crenulate; 

 strong spinous hairs, and longer weaker hairs in postero-lateral angles and scattered 

 over surface of segments ; whole abdomen nearly uniformly pale translucent brownish.
