408 Dr. J. L. Hancock's Further Studies of 



There are two species characterized as follows : 



1. Lateral lobes having the posterior angles obliquely dentate pro- 

 duced. Species from Penang Island. T. dentata, sp. nov. 



1.1. Lateral lobes having the jjosterior angles distinctly acute spinate 

 produced, spine transverse. Species Africana, T. spinata, sp. 

 nov. 



1. T. dentata, sp. nov. 



Body small, variegated with fuscous, head not at all exserted ; 

 eyes globose but rather small and not at all elevated ; vertex much 

 wider than one of the eyes, advanced nearly as far as the eyes, little 

 fossulate on each side, middle carina little crassate forward and little 

 produced, frontal costa in profile little j^rotuberant between the 

 antenna?, scarcely sinuate above and below ; posterior ocelli placed 

 between the middle of the eyes. Pronotum scabrous, deplanate, 

 somewhat convex between the shoulders ; process acute not reaching 

 to the apices of posterior femora ; median carina sinuate bicristate, 

 roundly compresso-elevated anteriorly above the sulci, subtuberculate 

 on the process ; dorsum between the humeral angles little dilated, 

 the angles distinctly carinate, little compressed, obtuse angulate, just 

 behind the shoulders over the elytra the lateral carinoe compresso- 

 elevated and here sinuous, here also at the base of process the dorsum 

 fossulate and fuscous ; abbreviated cariutne between the shoulders 

 compressed ; posterior angles of the lateral lobes laminate, flattened, 

 acute dentate produced, behind the denticles obliquely truncate. 

 Elytral apices widely rounded ; wings barely passing the process. 

 Posterior femora little incrassate, margins entire ; the second and 

 third pulvilli of the first tarsal articles equal in length, the first 

 small and spiculate below. 



Entire length of body, female, 7 mm.; pronotum 6 mm. ; posterior 

 femora 4 mm. 



One example from Prince of Wales Island (or Penang), 

 in the University Museum, Oxford. 



2. T. sjnnata, sp. nov. (Plate XXII, fig. 7.) 



Nearly allied to the preceding species, resembling it in stature and 

 general form ; colour grey ; vertex wider than one of the eyes ; 

 head not at all exserted ; frontal costa strongly jirotuberant between 

 the antennas, scarcely at all sinuate between the eyes ; maxillary 

 palpi having the apical articles white. Pronotum having the 

 posterior angles of the lateral lobes strongly laminate, transversely 

 acute spinate produced. Pulvilli of the first jjosterior tarsal articles
