80 MR. SMITH'S CATALOGUE OF HYMENOPTEROUS INSECTS 



2. Echinopla pallipes. E. nigra, hispida ; oculis prominentibus ; 

 abdomine globoso ; squaina in utroque latere spina horizontal ; 

 pedibus pallide testaceis. 



Worker. Length 2J,- lines. Black, rugose ; the abdomen vermiculate, 

 interpersed with slight elevations placed in great regularity over tli£ 

 entire upper surface, each elevation terminating in a hair ; the scape 

 and the mandibles ferruginous ; the eyes very prominent ; the palpi 

 and legs pale testaceous, with the tarsi rufo-piceous ; the peduncle 

 transverse, produced on each side into a short horizontal spine ; the 

 abdomen rufo-piceous. 



Hub. Borneo (Sarawak). 



It is very difficult to describe the sculpturing of this insect ; on the head 

 it is strongest ; the species strongly resembles E. melanarctos, but the 

 elevations are shorter, as well as the hairs at their apex. 



3. Echinopla striata. E. nigra; capite, thorace et abdomine lon- 

 gitudinaliter striatis ; thorace oblongo, subquadrato ; pedunculo trans- 

 verso. 



Worker. Length 3 lines. Black ; the head, thorax and abdomen finely 

 striated longitudinally ; the head with an obscure blue tinge ; the 

 palpi pale rufo-testaceous. Thorax : oblong, the margins denticulate, 

 the anterior margin rounded, the lateral margins narrowed to the 

 middle, and again widened posteriorly ; above slightly arched ; the 

 division of the pro- and meso-thorax distinctly marked by a suture ; 

 that of the meso- and meta-thorax by a deep strangulation ; the pe- 

 duncle of tbe abdomen incrassate, transverse, and armed on each side 

 by a stout spine. The entire insect thinly sprinkled with erect black 

 hairs. 



Hab. Malacca. 



Of this species I have only seen two individuals : I place it in this 

 genus with some hesitation ; but the antennae are similar ; the thorax 

 and scale of the abdomen of the same form ; the legs also are short, 

 as in Echinopla : the principal difference being, that the eyes are less 

 prominent ; it is altogether a very curious and remarkable species. 



Gen. Cataulacus, Smith. 



1. Cataulacus insula ris. C. niger; vertice spinis duabus postice 

 armato ; alis flavo-hyalinis ; metathorace bispinoso ; abdomine cor- 

 dato. 



Male. Length 3 lines. Black : head and thorax rugose ; the antenna?, 

 the eyes, the mandibles, the tibiae and the tarsi, ferruginous ; the 

 palpi pale ; the eyes very large and prominent ; the clypeus produced 

 and broadly truncate in front ; the hinder margin of the vertex 

 straight, margined, and having the posterior lateral angles produced 

 into stout acute spines; the outer margins of the spines serrated; 

 beneath are smaller spines at the lower lateral angles ; the wings sub-
