 pressis. Tibiae posteriores sat elongate, apicem versus leviter incras- 

 satse, extus baud denticulatis, angulo apicali inferiore calcari brevi, 

 alteroque ad angulum superiorem, tarsis tibiis plus duplo brevioribus, 

 compressis, unguiculis parvis. Prothorax angulis anterioribus subtus 

 excavatis. Elytrorum epipleura latissimse. Pygidium sub-perpendicu- 

 larse, elytris obtectum. Mesosternum sat magnum. Coxa intermedise 

 perdistantes. 



451- S. edwardsi, Sharp ; Rev. et Mag. de Zool. Paris, 1873, 

 p. 4. Supra opacus, subtus sat nitidus, obscure nigro-seneus, elytrorum 

 apice tibiisque piceis, palpis, antennis, tarsisque rufis ; capite prothora- 

 ceque dense punctatis ; hoc transverse, basi medio longitudinaliter 

 impresso ; elytris sericeo-opacis, obsolete striatis ; pectore sat crebre 

 punctate. 



Long, corp., if lin. 



Habitat. Nov. Zealandia. 



Collected by Mr. Henry Edwards (now of San Francisco). 



452. S. wakefieldi, Sharp; Ent. Mon. Mag., January, 1877. 

 Sub-quadratus, supra opacus, subtus sat nitidus, obscure nigro-seneus, 

 elytrorum margine plus minusve testaceo, pedibus rufis, antennis testa- 

 ceis clava fusca ; capite thoraceque dense punctatis, hoc basi medio 

 longitudinaliter impresso; elytris sericeo-opacis, obsolete striatis; pygidio 

 exsertas (sub-perpendiculare), leviter inflexo. 



Long., 4^ mm. ; lat, 3 mm. 



In the male the hinder part of the metasternum is slightly impressed 

 in the middle, and the apical ventral segment is a good deal shorter in 

 the middle than it is in the female ; otherwise the two sexes are quite 

 similar. 



Four individuals of this species were captured by Mr. Wakefield 

 (after whom I have the pleasure of naming the species) in the Otira 

 Gorge, Canterbury. 



OBS. This species is extremely similar to S. edwardsi, but is a little 

 larger, and the front tibia? are less curved, the metasternum is longer, 

 and the femora are red. In the individual from which I described 

 S. edwardsi, the pygidium is entirely immersed under the elytra, while 

 in the two individuals of 6". wakefieldi before me, it is quite exposed. 



It is therefore probable that the position of this part in the unique 

 individual of S. edwardsi is the result of an accident. The genus 

 Saphobius is very close to the Australian Homodesmius (which is pro- 

 bably synonymic with Canthonosoma, MacLeay), but has the hind tibiae 

 differently formed. 



453. S. nitidulus, n.s. Rather shining ; head and thorax pitchy, 

 the former reddish in front; elytra green on the middle, blackish at 

 the sides, with the suture reddened ; legs dark red, shining.
