l.oug'. 5 mm. 



This closely resembles tlie typical species S. rnfotestaca, Lewis 

 (Ann. & ]\Iag. Nat. Hist., iv, 1889, p. 274), but is darker in colour, 

 Avitli the emarp,ination of the head arcuate and not anguliir. The 

 head and thorax are sparsely punctured, and the latter furrowed 

 along its posterior half. The elytra have indistinct rows of 

 punctures and a single pair of strioe bordering the suture. The 

 pygidium is furnished with long, erect fulvous setae. 



A single specimen was obtained on the north coast of the island. 



16. Shoguna striata, Arrow, sp.n. 



Cylindrica, subdepressa, nitida, rufo-castanea ; capite prothorace- 

 que parcissime sat distincte punctatis, capitis fronte arcuatira 

 emarginato, oculis minutis, antennae clava 2-articulata, articulo 

 nono vix jn'ecedeutibus majore; prothoracis dorso subplano, medio 

 postice subsulcato, lateribus concavis; elytris fortiter strigatis, 

 utrisque ad apicem rotundatis. 



Long. 4 mm. 



Eather smaller and more depressed than the preceding species ; 

 the liead and thorax with large scattered punctures, the latter 

 longitudinally furrowed posteriorly. The eyes are very small, 

 and the ninth joint of the antennae is hardly larger than those 

 preceding it. The elytra are deeply striated, and the pygidium is 

 fringed with yellow hairs. 



Only a single specimen was found. 



The previously described species of the genus Shognna inhabit 

 Madagascar, Burma, Japan, and New Britain respectively. 

 Mr. Lewis mentions species from the New World, which he does 

 not think can be gencrically separated, but an examination of 

 these convinces me that they constitute a closely allied but 

 distinct genus. 



ONISCOMORPHA, Arrow, gen. nov. 



Caput elongatum, exsertura, emarginatum, oculi integri, ovales 

 remoti, antennae 11-artieulatae, clava elongata triarticulata ; pro- 

 thorax transversus, antice non capitis ad marginera attingens, 

 angulis anticis valde rotundatis, posticis emarginatis ; scutellum 

 transversum ; elytra parallela, postice parum attenuata, sub- 

 acuminata. 



Allied to Narcisn, and of similar appearance, but the head is 

 not sunk into the prothorax, and the eyes are entire, and situated 

 on the sides of the head, the upper and lower divisions being equal, 

 but without constriction or emargination. The facets are very 

 large. The antennal club is compact, and twice as long as broad,
