Tyrt^osus trilinealbus, n. sp. 



Black, with a slight bluish gloss. With rather sparse and 

 irregularly distributed sooty scales ; but prothorax with three 

 conspicuous lines of white scales ; a short oblique line of white 

 scales on each elytron close to scutellum, and similar scales on 

 suture on the posterior declivity. Legs with whitish and sooty 

 set«. 



Head with small partially-concealed punctures. Eyes with 

 rather smaller facets than usual, separated less than width of 

 rostrum at base. Rostrum not very long, sides distinctly in- 

 curved to middle ; with rather small clearly-defined punctures, 

 becoming larger and partially concealed about base. Antennae 

 inserted almost in exact middle of rostrum ; club rather large. 

 Prothorax rather strongly transverse, apex more than half the 

 width of base ; with moderately large, round, deep, sharply-cut 

 punctures, becoming very small and sparse at apex ; without 

 median carina. Elytra cordate, each separately rounded at 

 Tjase, and without subhumeral incurvature, sides evenly 

 rounded; with rows of rather narrow, suboblong punctures, in 

 narrow, shallow striae; interstices flat, wider than striae, the 

 second widest of all. Metas^termini about two-thirds the 

 length of the following segment : without an elevated ridge on 

 each side between coxae : punctures of episterna almost con- 

 tinuous. Abdomen with first segment slightly longer than 

 second and third combined, gently convex in middle, second 

 subequal to third and fourth combined : each of these with a 

 row of punctures across middle. Legs moderately long ; 

 femoral teeth acute but rather small ; all tibiae parallel-sided, 

 except at ends, and not dilated at apex. Length, 3 mm. 



Hah. — Queensland: Cairns district (A. M. Lea). Type, 

 I. 1317. 



Referred to Ttjrfa'osvs with hesitation on account of the 

 base of the elytra and rather finely faceted eyes. At first 

 sight it appears to belong to Gymnoyoropf eras , but the meta- 

 stemum is rather long, with conspicuous episterna. The meso- 

 sternal receptacle has rather thinner walls and the basal por- 

 tion smaller than usual, but the emargination is rather widely 

 U-shaped ; from some directions it appears to be open, but as 

 its wall at the base is directed slightly forwards, it must be 

 regarded as cavernous. The tarsi and antennae are almost as 

 black as the other parts. The type, judged by the abdomen, 

 appears to be a female. 



Tyrt^osus aberrans, n. sp. 



Black, antennae and tarsi of a rather dingy-red. Moder- 

 ately clothed with sooty scales, with many feeble spots of 

 stramineous or whitish ones. Legs and under-surface with 

 whitish setae.
