[October, 
accurately, adopts the name of neglectus for it, and says that he has 
seen specimens so named by Dahlbom himself in which the 3rd sub- 
marginal cell was triangular, and, therefore, assumes that Dahlbom 
made an error in his description. 
Both Wesmael and Thomson, however, agree that the £ to which 
Dahlbom gave the name of minutulus is the £ of the present species ; 
and I have, therefore, adopted this name, as it clearly has the priority, 
having been used by him in his “ Dispositio,” in 1842 ; whereas cel- 
lularis and neglectus were only described in 1845.

Same coloration, &c., as gibbus and its allies, but easily dis- 
tinguished, as the B has the apical ventral plate slightly carinated, 
and armed near the apex with a long pendant 
spine ; the $ is more difficult to recognise, but 
may be known by the somewhat carinated, com- 
pressed apical segment beneath. 
I called this species in my notes (ante, p. G8) 
abnormis , Dahlb., but I see now that it clearly 
belongs to Wesmaeli. Abnormis also has the pendant spine in the 
but has the base of the ventral plate flat, and an oval fovea before 
the spine.

Black, with the two basal segments of the abdomen red, the basal segment 
in the £ often with a longitudinal black stripe at its base. 
Hoad and thorax finely punctured, covered with a fine sericeous, and in some 
lights silvery, pubescence, the pubescence on the coxae and mesopleurae denser and 
more distinctly silvery, wings slightly dusky with a darker stripe through the 2nd 
and 3rd sub-marginal cells, and a darker patch in the 3rd discoidal cell ; beyond the 
apex of the 3rd sub-marginal is an irregularly-shaped clearer spot, sometimes 
wanting ; the apex of the wing widely dusky. Abdomen shining, 3rd and following 
segments covered with a fine sericeous-grey pubescence ; 5th segment in 
the 9 with a few longer hairs, and 6th rather thickly covered with them. 
Beneath with a few scattered hairs. Apical segment carinated at the 
apex ; <3 with the anal ventral valve hairy and narrow, slightly Apical seg- 
widened at the apex and truncate (see figure) ; posterior calcaria not ^anmluP'i 
two-thirds as long as the basal joint of the tarsi. Length, 6 — 8 mill. 
Very distinct from any of the otters of tbe exaltatus group, in 
the shape of the ventral anal plate of the and the absence of the 
clear round spot in the wings of the 9 .
