Ceratiscus laticeps, new genus and species. 



A large female Phasmid, taken on Jan. 27, apparently represents a new genus 

 and species. It belongs to the subfamily Clitumninoe, but, unlike the other members 

 of that group, it is a large insect with very elongate operculum. The antennas are 

 short, being considerably less than one half as long as the anterior femora, and con- 

 sist of twenty distinct segments ; the first subquadrate and flattened, the second 

 nearly round, the third twice as long as broad, the following two or three transverse 

 and closely united, and the remainder longer than broad, the terminal eight or nine 

 being twice or more than twice as long as broad. The head is very broad, nearly as 

 broad as long, much broader than the thorax and smooth, except two small round de- 

 pressions on top, behind and between the bases of the antennas. Pronotum scarcely 

 twice as long as broad, with a transverse impression, borders emarginate ; meso- 

 notum and metanotum unarmed, the former more than six times as long as the pro- 

 notum, the latter somewhat shorter, being but five times the length of the pronotum. 

 Intermediary segment not clearly indicated. Body smooth. Operculum as long as 

 the basal four segments of the abdomen. Cerci short and pointed, convex on the 

 inner side. Legs moderately slender ; anterior femora strongly curved basally and 

 dorsally, serrated with strong teeth ; tibiae unarmed ; intermediate femora and tibiae 

 armed with a single angular lobe near the base, above on the tibiae and below on the 

 femora ;* posterior legs armed as the intermediate, all the lobes being scarcely higher 

 than the width of the limbs bearing them. All the tarsi have the basal segment 

 longer than all the rest taken together. 



Entire length, exclusive of the operculum, 123 mm.; head, 6 mm.; prothorax, 4 

 mm.; mesothorax, 27 mm.; metathorax, 20 mm.; abdomen, 66 mm.; cerci, 1 mm.; 

 operculum, from the point of attachment to the tip, 35 mm.; anterior femora, 31 mm.; 

 anterior tibije, 38 mm.; intermediate femora, 27 mm.; posterior femora, 23 mm.; 

 width across widest part of the head, 5 ram.; of pronotum, 3 mm. 



Type. — No. 8102, U. S. National Museum. 



In many ways this species resembles the Bacteria clinteria of West- 

 wood, and it may, upon comparison with the type of that species, 

 prove identical with it. But I scarcely think so, as it differs from the 

 figure and description of that insect in having the head proportion- 

 ately much broader and by having the middle and posterior legs with 

 angularly lobate femora and tibiae. 



* One of the tibire lacks the lobe.
