lines; dorsal carina percurrent, a deeply impressed dot on each side of its 

 base; dorsal crest somewhat elevated, much compressed, strongly com- 

 pressed anteriorly at base and posteriorly behind middle, the highest 

 point of crest at beginning of posterior third, from which point it gradu- 

 ally slopes anteriorly in a gentle curve continuous with anterior third of 

 prothorax, posteriorly sloping for a short distance, then forming an obtuse 

 angle; at the base another obtuse angle is formed, from which the median 

 carina curves gently to the apex; lateral angles a little prominent; tegmina 

 with basal half coriaceous, apical half subcoriaceous, a brown spot at 

 apex. Chest below is dark yellow, coxae piceous. Legs yellow and hairy 

 Abdomen yellow. Length 6 mm.

Described from one % from Dr. Riley, who has so kindly 

 favored me with much valuable material from the National collec- 

 tion (type in collection of F. W. G.). 



This species resembles coqidlletti; the dorsal crest is reclined, 

 while in that species it is upright. 



Telamona mexicana Stal. (?) cf- 



In the material sent to me recently from the National Museum 

 by Dr. Riley, for determination, is a ^ member of this genus, 

 which agrees very closely with the description of mexicana 9 

 in Bid. Memb. K. p. 249, No. i. It differs, however, in the ab- 

 sence of the brown spot on tegmina, and the legs are immaculate 

 yellow, tips of tarsi piceous; dorsal crest nearly thrice as long as 

 high at base. 



I believe this to be the % of viexicana; if it should prove to 

 be undescribed it may be called ^?//<://ra. Length 7 mm.

PLATYCOTIS Stal. 



Platycotis minax n. sp. 9- — l^ale yellow, densely punctured, very much 

 depressed, appearing broad and flat. Head bright yellow, with a longi- 

 tudinal median carina. Prothorax light yellow, a transverse linear im- 

 pression just back of base on each side of carina, the impression almost 

 a fascia; anterior horn extending upward and forward, much compressed, 

 anterior edge nearlj' straight, posterior edge convex and brown; on each 

 side of horn two or three lateral carmae extending from base to apex; 

 horn about two and a half times as long as broad; at posterior base is an 

 obtuse angle, behind which is a slight convexity, thence straight to apex, 

 which does not reach tip of abdomen; tegmina subcoriaceous, extend far 

 beyond tip of abdomen, light yellow, vems darker; below yellow. Length 

 to apex of tegmina 5 mm.; including anterior horn 6.5 mm.
