M^r. Smith—

Woodcuts to serve merely to show general difference between sexes: must be neatly executed & finished.—²

Chiasognathus Grantii.— fig. of male, reduced to half or third nat. size   Head & thorax of female equally reduced.³

Bledius Taurus— male magnified twice or if necessary thrice: head & thorax of female equally magnified.— Viewed laterally & rather obliquely.—⁴

Please observe, that figures ought to be reduced (or magnified) as much as is compatible with perfect distinctly of Horns.

In each case male & female, in female the head, thorax & base of elytra sufficient.— Figures lateral, seen a little obliquely from above.—in following order.— about size of figure I must trust to your judgment. Please mark in each case how much reduced.— The Beetles must be neatly shaded; & the legs arranged naturally.

Attend particularly to degree of development of rudiments of Horns in the females of the latter species.

(Crabro cribrarius, male & front part of female.)⁸

(Taphroderes distortus   Male magnified & Head & thorax of female.)⁹

(Pneumora male & female)¹⁰
