2 aut plus minus rufescens aut totus niger. Macule pronotales 
bicolores. Scutellum seepius binotatum, tegulis subtestaceis.

In this and the three preceding species the antenne are very 
clavate, the fifth joint being wider than long and the following 
becoming still more transverse. The males, except that of 
P. debilis, are not known. In this male the antenne are very 
strongly clavate, the fifth joint not longer than its apical width, 
the sixth and seventh strongly transverse. Inall there are twelve 
joints, the three apical ones recurved to form a small hook, the 
preceding one being larger, but small. The wings are nearly 
hyaline, except along the costa, in one example, darker in the 
others, which are in abraded condition. One example in the 
Oxford Museum bears a MS. name, ‘‘ Alastor pusillus Sauss.,” 
but this is clearly an error.

82. PARALASTOR BRUNNEUS Sauss. 
With this species is begun a short series of allied species, which 
are quite distinct from any others by the form of the second ventral 
segment, which, behind the longitudinally costate suleature, rises 
very obliquely from this to a height not, or but little, exceeding 
the level of the base of the segment. ‘he clypeus is always very 
distinctly emarginate and plentifully and coarsely punctate, the 
punctures in the male being, however, more feebly impressed than 
in the female. The tegulz, over at least a considerable part of 
their surface, always bear coarse punctures, the puncturation 
being frequently rugose, but owing to the generally pale colour 
of the surface, the puncturation is usually less conspicuous than 
it would be were the tegule dark in colour.
