23. Tesseratoma forticornis. 



Nigra, sparse et aspere punctata, subtus testacea ; antenna fulvm ; thorax 

 testaceo fascia tus, cornubus latis rectis subascendenlibus spatii 

 intermedii dimidio cequilongis ; scutelli discus obscure ruf us ; venter 

 piceo vittalus ; ala anticte ruf a, luteo venosce. 



Black, testaceous beneath. Head, thorax and scutellum thinly and 

 roughly punctured. Eyes testaceous. Antennae tawny, less than half the 

 length of the body ; second joint longer than the third ; fourth longer than 

 the second. Thorax with a testaceous smooth band extending along part 

 of the fore side of the horns; sides in front transversely striated ; horns 

 broad, hardly acute, directly diverging, very slightly ascending, about half 

 the length of the intermediate part. Scutellum dark red in the disk, 

 grooved and attenuated towards the tip. Sternal keel lanceolate, extending 

 to the head, notched behind and there receiving the ventral spine. Abdo- 

 men beneath with a piceous stripe which does not extend to the tip; hind 

 angles of the apical segment rounded. Legs testaceous. Fore wings red,

21. Tesseratoma semicuprea. 



Picea, dense et subtililer punctata ; antenna nigra, articulo 4o apieetn 

 versus luteo ; thorax angiitis posticis rotundatis productis, margine 

 postico fere redo; scutellum transverse et sublilissitne striatum; 

 pectus antice obscure fulvum ; venter scilissime stria tus ; alee aniicic 

 cuprece.

 border nearly straight. Scutellum transversely and very finely striated. 

 Pectus dark tawny in front. Sternal keel dark tawny, extending to the 

 head, compressed in front, oblique at the tip, emarginate at the base. 

 Abdomen longitudinally and very finely striated in the disk beneath ; hind 

 angles of the segments successively more elongated and acute, those of 

 the apical segment extending as far as the two intermediate spines. Fore 

 wings cupreous, extremely finely punctured; membrane also cupreous. 

 Hind wings deep blue. Length of the body I 1 lines. 



Closely allied to T. picea and to '/'. lucluosa, bul the lore part of ihi
