broad irregular posterior band, in width about one-third of the length 

 of the segment ; or with large spots in place of a band. Ant. 3 with 

 a basal and an apical spot ; ant. 4 dull purplish except basally. Fore 

 tibiotarsi with a little pigment proximally and considerable pig- 

 ment distally; mid legs unpigmented; hind trochanters slightly pig- 

 mented; hind femora purplish except apically. Ventral tube un- 

 pigmented. Manubrium with a dorso-lateral stripe on each side. 

 Eyes 8 + 8. Antennae two and one-half times as long as the head, or 

 seven-tenths as long as head and body ; segments as 25 : 33 : 33 : 55 ; 

 last segment elliptico-cylindrical, obscurely and irregularly annulate 

 distally. Mesonotum projecting over the head to an unusual degree. 

 Fourth abdominal segment about eleven times as long as the third. 

 Tibiotarsi each with two subsegments, the distal subsegment two- 

 fifths as long as the entire segment. Unguis (fig. 59) slender, al- 

 most straight, with a pair of conspicuous lateral teeth two-thirds 

 from the base and two pairs of inner teeth; the proximal pair two- 

 fifths from the base; the distal pair midway between the proximal 

 and the apex. Unguiculus narrowly lanceolate, extending four-fifths 

 as far as ungTiis. Tenent hair strong, as long as the inner margin of 

 the unguis. Manubrium five-sevenths as long as dentes. Dentes 

 crenulate dorsally, the crenulations ending at a distance from the 

 apex equal to twice the length of the mucro. Mucro (fig. 60) rela- 

 tively long, strongly rounded ventrally; apical tooth large; ante- 

 apical small, inclined anteriorly; proximal spine short, acicular. 

 Comparatively few setae are present on head and body, which are 

 densely scaly ; the scales being mostly elliptical. The posterior border 

 of the fourth urotergite bears a fringe of straight, closely set setae, 

 directed backward. Scales occur on the antennae and ventrally on 

 the dentes except distally, where there are many long fringed setae. 

 Length, 2 mm. and 2.4 mm. 



This description was made from two types given to me by Doctor 

 MacGillivray. The original description of the antennae was evi- 

 dently based upon one of these types in which the antennae are 

 deformed.

Genus SALINA MacGillivray 



Salina, MacGilliyeay, 1894 

 Cremastocephalus Schott, 1896 



A study of my three types of Salina hcmksii MacGillivray shows 

 that Cremastocephalus Schott is a synonym of SoMna MacGillivray, 

 a genus which had not been recognized since its description. I regret
