narrow as compared with those of other OrypfamorpJicB, as Olliff 

 seems to imply they are in optaia. 



C. triguttata, Waterh. la the description of this species, as in 

 that of C optata, Oil., the sculpture of the head is characterised 

 by the word ^'' coriaceous^' without reference to their being any 

 distinct punctures, with which no Cryptamorpha known to me 

 agrees. Several species before me have the surface of the head 

 more or less coriaceous, but there is in all of them a well defined 

 system of larger punctures on the coriaceous surface. C. triguttata 

 is said to have " an elongate spot on the suture of the elytra near 

 the apex," which I cannot find in any of the specimens before me 

 — whatever postmedian dark mark there is near the apex being 

 always an ill-defined transverse fascia, which is more or less 

 traceable in almost all the Gryptamorphce that I have seen and is 

 not, I think, specific — specimens where it is wanting being mere 

 varieties. Waterhouse's species is described from S Australia — 

 from which locality I have seen mxny examples of Cri/ptamorpha 

 — and I find it difficult to believe that I have not seen either optata 

 or triguttata^ but I am obliged to consider that such is the case. 

 C. peregrina, sp. nov. Sat elongata ; sat angusta ; sat nitida ; 

 piiis longis erectis sparsim vestita ; rufo-ferruginea, in pro- 

 noti (hoc nonnihil cupreo) lateribus et in elytris indetermi- 

 nate obscuriore, capite haud coriaceo, crebre fortiter punc- 

 tulato, utrinque bistriato, striis sat parallelis, externa minus 

 perspicua juxta oculum, interna integra subtili sed bene 

 definita ; prothorace vix transverso, postice sat angustato, 

 subtilius aspere confluenter punctulato, lateribus sat sequali- 

 ter vix arcuatis denticulis setiferis circiter 6 armatis (majori- 

 bus 2 ad angulum anticum, 1 ad angulum posticum, ceteris 

 minutis); elytris sat grosse punctulato-striatis, inters titiis 

 planis subtiliter punctulatis. Long., If l.j lat., | 1. 

 The subnitid surface and deep close puncturation of the head 

 associate this species with C. Victoria, Blackb., and G. delicatula, 

 Blackb. The former is much larger with inter alia its prothorax 

 — not narrowed hind ward from close to the apex, as in this 

 species but — narrowed only close to the base and with its lateral 

 denticulations all minute and subequal. C. delicatula is very 

 close to this species but has inter alia a more decidedly transverse 

 prothorax and (especially) the puncturation of its head consider- 

 ably finer and closer and asperate.

PSAMMCECUS. 



No species really attributable to this genus has hitherto been 

 to my knowledge recorded as Australian. Psammcen, however, 

 seem to be fairly numerous in tropical Queensland, The follow-
