indispensable ; no coherent line of work can be pursued without 

 them ; and to grope blindly through a number of disconnected 

 experiments without any clear notion of what we expect to find, 

 or what we are looking for, is to work wastefully, half-uselessly, 

 and stupidly. But hypotheses are valuable only as schemes of 

 working, and utterly illusory without actual verification. Without 

 further comment, however, we will now proceed to consider the 

 actual experiments, and their results.

DESCRIPTIONS OF SOME NEW SPECIES OF CHINESE 



RHYNCHOTA. 



By W. L. Distant. 



I previously described (ante, p. 90) three new species of 

 Cicadidse, contained in a small collection, placed in my hands by 

 Mr. J. H. Leech. The following descriptions refer to other 

 novelties from the same source, and we may confidently anticipate 

 considerable accession to the number of known species of the 

 order, when the Chinese insect fauna is more available for study. 



HETEROPTERA. 



Fam. PENTATOMID^l. 



Subfam. ASOPIN^. 



Neoglypsus opulentus, n. sp. 



Ochraceous, thickly covered with dark punctures, and more or less 

 shaded with metallic green ; connexivuni ochraceous, with a black spot on 

 each side of the segmental sutures. Body beneath and legs pale ochraceous, 

 some small sternal discal spots and the stigmata black. Antennae dark 

 ochraceous, with the apical halves of the third, fourth, and fifth joints 

 black ; joints (excluding basal) almost subequal in length. Head with the 

 lateral margins distinctly recurved ; pronotal angles strongly produced into 

 obtuse spines, straight, and directed outwardly. Pronotum and scutellum 

 very coarsely punctate. Corium finely punctate. Long., 20 mm. Exp. 

 pronot. angl., 11£ mm. 



Hab. Chang Yang. (Pratt.) 



Allied to the only other described species of the genus, 

 N. viridicatus, Dist., from Japan, but differing by the obtuse 

 pronotal angles, &c. 



Subfam. PENTATOMIN/E. 

 Tropicoris illuminatus, n. sp. 



Very dark purplish brown, with the following yellow markings : — A 

 short oblique fascia on each anterior lateral area of the pronotum, and a 

 small central spot on disk of same, the apex of the scutellum, a spot in each 

 lull in I angle, and a central longitudinal fascia to same. Connexivum 

 ochraceous, with large blackish spots. Body beneath ochraceous; some 

 centra] sternal spots, the under side of pronotal angles, stigmata, and a
