504 ON AUSTRALIAN ANTHIOlDAE, 



FOEMICOMUS INTEER0PTUS, n.Sp. 



Dark reddish-brown, elytra darker, but with two pale interrupted fasciae, 

 palpi and most of legs paler. With rather sparse, pale pubescence, but fairly 

 dense on sides of prothorax posteriorly, dense on elytral fasciae and on sides of 

 under surface; a few straggling hairs scattered about. 



Head subovate, rather feebly convex, hind angles moderately rounded off; 

 with crowded and small asperate punctures, sparser (but still crowded) in front 

 than behind; with a feeble median line. Eyes small, medio-lateral and rather 

 prominent. Prothorax with sides widest near apex, where they are evenly 

 rounded, then oblique but with a feeble incurvature to base ; punctures much as 

 on base of head; median line scarcely traceable. Elytra elongate-elliptic; basal 

 half with rather dense and moderately large, sharply defined punctures, becoming 

 very small posteriorly. Intercoxal process of abdomen rather wide and truncate. 

 Femora stout, the hind ones strongly clavate and with a large, acutely triangular 

 tooth. Length, 3.5 — i.5 mm. 



ffa6.— Queensland : Townsville (F. P. Dodd). 



At first glance like some of the fomis of F. quadrimaculatus, but elytral 

 punctures sparser and much more distinct on the basal half, and prothorax 

 shorter but with somewhat similar pubescence; the prothoracic punctures are 

 stronger than on F. Kingi. The head and prothorax are subopaque, due entirely 

 to the punctures; the elytral fasciae are rendered very distinct by their clothing 

 (which, however, appears to be easily abraded), the fii-st is at the basal third 

 and is interrupted close to the suture, the other is at the apical third and its 

 sutural interruption is wider. I can find no external indications of sex in the 

 three specimens under examination. 



FORMICOJIDS LATIBASIS, n.sp. 



Flavous, head and prothorax somewhat fermginous, elytra with two pale, 

 interrupted fasciae. , Rather sparsely clothed, but on the elytral fasciae ' and 

 parts of under siu'face more densely so. 



Head briefly ovate, widest almost at base, where the angles are feebly 

 rounded off. Eyes small and medio-lateral. Prothorax slightly wider than long, 

 widest and strongly rounded near apex; with a distinct, open, medio-basal fovea. 

 Elytra elongate-ovate; with dense and minute punctures throughout, with some 

 larger (but still small) ones becoming rather numerous towards base. Length, 

 4.5 mm. 



Hab. — South Australia: Kilkerran (Blackburn's collection). 



The type may be immature but is structurally sufficiently distinctive to be 

 named. It is closely allied to the preceding species, with abdomen and hind 

 femora similar, but diffei-s in having the head decidedly wider, with the hind 

 angles less rounded off; the prothorax is wider with the medio-basal fovea dis- 

 tinct (on that species it is hardly indicated), and the elytral punctures are smaller; 

 the punctures on the head and prothorax are of the same nature, but are smaller 

 and the median line in the former is even less distinct; its clothing is also 

 sparser. It is also allied to F. qiiadrimaculatiis, but the head is at least half as 

 lai'ge again, the prothorax is shorter and with a medio-basal fovea; this is one 

 (the most distinct) of three enlargements of the sub-basal impression. 



FORIIICOMUS PUBIFASCIATUS, n.sp. 



Black; head, prothorax, antennae, palpi and legs more or less red. Finely 

 pubescent, but the elj'tra with two intennipted fasciae of white pubescence: one 

 at the basal third, the other at the apical third.
